Choosing an egg donor in the USA can be life-changing for individuals and couples who need donor eggs to build a family. The process is medically advanced, widely available, and supported by a mature network of fertility clinics, donor agencies, egg banks, attorneys, and mental health professionals. At the same time, it can feel overwhelming because costs vary widely, donor requirements are detailed, success rates depend on several factors, and not every agency operates with the same level of transparency or ethics.
Egg donation is commonly used by women with diminished ovarian reserve, premature ovarian insufficiency, age-related infertility, repeated IVF failure, genetic conditions they do not wish to pass on, or a history of ovarian surgery or cancer treatment. It is also used by male same-sex couples and single intended fathers together with a gestational carrier. In the United States, donor egg IVF is a well-established treatment, and the recipient’s age has a much smaller impact on embryo implantation than it does in IVF using one’s own eggs. However, success is not guaranteed, and intended parents should understand the medical, legal, emotional, and financial aspects before committing.
What Is Egg Donation in the USA?
Egg donation is a fertility treatment in which a donor provides eggs that are fertilized with sperm in a laboratory to create embryos. Those embryos may be transferred to the uterus of the intended mother or a gestational carrier, or they may be frozen for future use. In the USA, egg donation can be arranged through several pathways: a fresh donor cycle, frozen donor eggs from an egg bank, a known donor, or an agency-recruited donor.
In a fresh donor egg cycle, the donor undergoes ovarian stimulation specifically for the intended parents. Her eggs are retrieved and fertilized shortly after retrieval. Fresh cycles may produce more eggs and potentially more embryos, but they require coordination between the donor, clinic, and recipient. In a frozen donor egg cycle, eggs have already been retrieved, tested, frozen, and stored. This can shorten the timeline and reduce scheduling complexity, though the number of eggs purchased is usually limited to a set lot.
A known donor may be a friend, sister, cousin, or another person known to the intended parents. Known donation can feel personal and meaningful, but it still requires medical screening, psychological counseling, legal contracts, and careful boundary-setting. An agency donor is typically recruited and screened by a donor agency and then matched with intended parents based on medical eligibility, personal preferences, family history, physical characteristics, education, values, and availability.
How Much Does an Egg Donor Cost in the USA?
The total cost of using an egg donor in the United States varies significantly. A full donor egg journey may cost anywhere from approximately $20,000 to more than $70,000, depending on whether the eggs are fresh or frozen, whether an agency is involved, the donor’s compensation, the fertility clinic’s fees, medication costs, legal fees, genetic testing, embryo freezing, and whether a gestational carrier is also needed. For intended parents who require surrogacy in addition to donor eggs, the total cost is much higher and often exceeds six figures.
It is important to separate donor compensation from the total treatment cost. Donor compensation is the amount paid to the egg donor for her time, effort, discomfort, and commitment. The total treatment cost includes agency fees, clinic procedures, medications, screening, legal services, embryo creation, lab fees, and often travel. Some clinics and egg banks offer package pricing, while agencies often provide itemized estimates.
| Cost Category | Typical USA Range | What It Usually Covers |
|---|---|---|
| Egg donor compensation | $8,000–$20,000+ | Donor’s time, injections, monitoring visits, retrieval, and temporary lifestyle restrictions |
| Agency fee | $6,000–$12,000+ | Recruitment, coordination, donor database access, match management, administrative support |
| Medical screening | $1,000–$4,000 | Bloodwork, infectious disease testing, ultrasound, ovarian reserve evaluation, genetic carrier screening |
| Donor medications | $3,000–$8,000 | Injectable fertility medications used to stimulate the ovaries |
| IVF laboratory and egg retrieval fees | $10,000–$25,000 | Monitoring, egg retrieval, fertilization, embryo culture, embryo transfer, clinic procedures |
| Legal fees | $1,500–$5,000 | Donor agreement, independent legal representation, parental rights provisions |
| Psychological evaluation/counseling | $500–$1,500 | Assessment of donor readiness, informed consent, counseling for known donation or disclosure issues |
| Travel and monitoring expenses | $500–$6,000+ | Flights, hotel, meals, local monitoring, companion travel if required |
| Embryo freezing and storage | $1,000–$3,000 initially; $500–$1,200/year storage | Cryopreservation and annual storage of remaining embryos |
A frozen donor egg bank option may be less expensive and more predictable. Many egg banks sell lots of six to eight frozen eggs, with prices often ranging from about $15,000 to $30,000 for the eggs alone, plus clinic fees for thawing, fertilization, embryo culture, and transfer. Total costs often fall around $20,000 to $45,000, depending on the clinic and whether services are bundled.
A fresh donor cycle through an agency may cost more, often around $35,000 to $65,000+, because it includes donor compensation, agency coordination, medications, retrieval, and extensive screening. Some fresh cycles produce a larger number of eggs, which can be helpful for families wanting multiple children from the same donor. However, more eggs do not automatically mean more healthy embryos, and outcomes depend on egg quality, sperm quality, laboratory performance, and embryo genetics.
Intended parents should also ask about refund policies and what happens if the donor is disqualified, withdraws, responds poorly to stimulation, or produces fewer eggs than expected. Some programs offer guarantees, replacement donors, shared-risk plans, or multi-cycle packages, but the fine print matters. A lower upfront price is not always the lower-risk option if it excludes essential services.
Egg Donor Requirements in the USA
Egg donors in the USA must meet medical, psychological, legal, and lifestyle requirements. The exact criteria vary by fertility clinic, egg bank, and agency, but most reputable programs follow guidance from professional organizations such as the American Society for Reproductive Medicine, commonly known as ASRM, as well as federal requirements for tissue donor screening established by the U.S. Food and Drug Administration.
Most programs prefer donors between 21 and 34 years old, though some clinics set narrower age ranges, such as 21 to 30 or 21 to 32. Younger donors generally have a higher number of eggs and lower rates of chromosomal abnormalities, but age is only one factor. A donor also needs appropriate ovarian reserve, a healthy medical history, and the ability to complete a demanding schedule of injections, monitoring appointments, and a minor surgical egg retrieval.
| Requirement Area | Common Standard | Why It Matters |
|---|---|---|
| Age | Usually 21–34 | Younger eggs are generally associated with better embryo potential and lower aneuploidy risk |
| General health | No serious uncontrolled medical conditions | Protects donor safety and supports predictable response to stimulation |
| BMI | Often about 18–30, depending on clinic | BMI can affect medication dosing, anesthesia safety, and response to stimulation |
| Ovarian reserve | Acceptable AMH, AFC, and hormone levels | Helps estimate how many eggs may be retrieved |
| Infectious disease screening | FDA-required testing for certain communicable diseases | Reduces risk of disease transmission through donated reproductive tissue |
| Genetic screening | Carrier screening and detailed family history | Helps identify inherited conditions and match with sperm source testing |
| Mental health evaluation | Psychological interview and standardized assessment | Confirms informed consent, emotional readiness, and ability to complete the process |
| Lifestyle | Non-smoker, no substance misuse, reliable schedule | Supports donor safety, cycle compliance, and egg quality |
Donors also complete a detailed family medical history. This includes information about parents, siblings, grandparents, aunts, uncles, and sometimes cousins. Programs look for patterns of hereditary cancers, heart disease, psychiatric illness, neurological conditions, developmental disorders, autoimmune diseases, and genetic syndromes. A family history is not expected to be perfect; almost every family has some medical issues. The purpose is not to find a flawless donor, but to identify risks clearly and responsibly.
Psychological screening is just as important as medical screening. Egg donation involves hormone injections, physical discomfort, privacy considerations, future questions from donor-conceived children, and sometimes contact preferences with the recipient family. A qualified mental health professional should assess whether the donor understands the process, is free from coercion, and can make a thoughtful decision.
Intended parents should be cautious if an agency advertises donors who appear to bypass screening or offers immediate access to a donor without proper medical and psychological evaluation. A donor profile is only the beginning. Eligibility must be confirmed by the clinic before a cycle begins.
Egg Donor IVF Success Rates in the USA
Donor egg IVF success rates are generally higher than success rates for IVF using a patient’s own eggs at advanced reproductive age. This is because egg quality is one of the strongest drivers of embryo quality, implantation, miscarriage risk, and live birth. When eggs come from a young, healthy, well-screened donor, the recipient’s age is less influential than it would be in a traditional IVF cycle using her own eggs.
In broad terms, many U.S. fertility programs report live birth rates per embryo transfer in the range of approximately 40% to 60% for donor egg cycles, though this can vary by clinic, embryo stage, embryo testing, sperm quality, uterine factors, and whether the embryos are fresh or frozen. Some individual clinics may report higher rates in selected patients, while others may be lower. It is better to evaluate official clinic data through sources such as SART or CDC reporting rather than relying only on marketing claims.
Success can be measured in different ways. A clinic may quote pregnancy rate per transfer, clinical pregnancy rate, ongoing pregnancy rate, live birth rate, or cumulative live birth rate. These are not the same. Live birth rate is usually the most meaningful statistic because it measures the outcome intended parents care about most: taking home a baby. Cumulative live birth rate may be higher because it includes multiple embryo transfers from one egg retrieval or egg lot.
| Factor | Impact on Success | What to Ask |
|---|---|---|
| Donor age and ovarian reserve | Affects egg number and quality | What were the donor’s AMH, AFC, and previous cycle outcomes? |
| Sperm quality | Can affect fertilization and embryo development | Is semen analysis normal? Is ICSI recommended? |
| Embryo laboratory | Lab quality strongly affects embryo development and survival after thawing | What are the clinic’s donor egg live birth rates and thaw survival rates? |
| Uterine health | Fibroids, polyps, adhesions, or inflammation may reduce implantation | Should I have a saline sonogram, hysteroscopy, or endometrial evaluation? |
| Embryo testing | PGT-A may help select chromosomally normal embryos in some cases | Is PGT-A recommended for donor egg embryos in my situation? |
| Single vs. multiple embryo transfer | Multiple embryo transfer can increase twin risk without guaranteeing a healthy birth | Does the clinic recommend elective single embryo transfer? |
One common misconception is that donor eggs guarantee pregnancy. They do not. A donor egg cycle can fail due to fertilization problems, poor embryo development, uterine factors, embryo chromosomal abnormalities, immune or endocrine conditions, or simply chance. Another misconception is that all young donors have equal outcomes. Donors vary in egg quality, response to medication, family history, genetic carrier status, and previous retrieval results. If a donor has donated before, prior cycle outcomes can be very informative, but they still do not guarantee future results.
Frozen donor eggs are convenient, but success depends heavily on the egg bank’s freezing technique, storage procedures, thaw survival, and the receiving clinic’s lab expertise. Many programs have excellent outcomes with vitrified donor eggs, but intended parents should ask whether the quoted success rate applies to the same egg bank, same clinic, and same patient population.
If the goal is to have more than one child genetically related to the same donor and sperm source, intended parents should discuss this early. A single frozen egg lot may or may not produce enough embryos for multiple children. A fresh cycle may provide more eggs, but that also depends on donor response. Some families purchase more than one frozen egg lot or choose a fresh cycle for this reason.
The Egg Donation Process: Step by Step
Although each clinic and agency has its own workflow, the egg donation process in the USA usually follows a predictable sequence. Understanding this sequence helps intended parents plan time, budget, emotional energy, and decision-making.
- Initial fertility consultation: The intended parent or parents meet with a reproductive endocrinologist to review medical history, diagnosis, uterine evaluation, sperm testing, and whether donor eggs are medically appropriate.
- Choose fresh donor, frozen eggs, known donor, or agency donor: The choice depends on budget, timeline, desire for future siblings, donor preferences, and clinic recommendations.
- Donor matching: Intended parents review donor profiles, which may include physical characteristics, education, personal essays, childhood photos, adult photos, family history, interests, and prior donation results.
- Medical and genetic screening: The clinic evaluates the donor and the sperm source. Genetic carrier screening is especially important to reduce the risk of both donor and sperm provider carrying variants in the same condition.
- Legal contracts: Independent attorneys prepare and review an egg donation agreement. This should happen before medications begin.
- Psychological evaluation and counseling: The donor undergoes assessment, and intended parents may receive counseling about disclosure, expectations, grief related to not using one’s own eggs, and future contact preferences.
- Ovarian stimulation and monitoring: In a fresh cycle, the donor takes injectable medications for about 10 to 14 days and attends ultrasound and bloodwork appointments.
- Egg retrieval: Eggs are collected in a minor procedure using ultrasound guidance. The donor usually goes home the same day.
- Fertilization and embryo culture: Eggs are fertilized with sperm, often using ICSI, and embryos are grown in the lab for several days.
- Embryo transfer or freezing: A selected embryo is transferred to the recipient or gestational carrier, and remaining suitable embryos may be frozen.
- Pregnancy testing and follow-up: A blood pregnancy test is performed about 9 to 12 days after embryo transfer, followed by repeat testing and early ultrasound if positive.
Timelines vary. Frozen donor eggs may be available quickly, sometimes allowing treatment to move forward within one to three months. A fresh agency donor cycle can take three to six months or longer, depending on donor availability, screening, legal clearance, clinic scheduling, and travel. Known donor arrangements can also take time because counseling and legal discussions may be more complex.
Legal Considerations for Egg Donation in the USA
Egg donation is legal in the United States, but laws and best practices vary by state. A carefully drafted legal agreement is essential. The agreement typically confirms that the donor does not intend to be a legal parent, that the intended parents will have parental rights and responsibilities, how compensation and expenses are handled, what happens to unused embryos, how confidentiality or future contact is managed, and what medical information may be shared later.
Each party should have independent legal counsel. This is particularly important because the donor and intended parents have different interests and responsibilities. If one attorney represents everyone, conflicts may arise. Reputable agencies and clinics generally require legal clearance before the donor starts stimulation medications.
Anonymous donation, semi-open donation, and known donation all exist in the USA. However, the meaning of “anonymous” has changed in the era of consumer DNA testing and online genealogy databases. Even if identities are not shared at the time of treatment, future identification may be possible. Intended parents should think carefully about what they will tell their child, how they will preserve donor information, and whether the donor is open to future medical updates or contact.
Many mental health professionals and donor-conception advocates encourage age-appropriate disclosure to donor-conceived children. This does not mean every family must have the same type of relationship with a donor, but secrecy can become difficult and emotionally complicated over time. Before choosing a donor, intended parents should ask whether the donor is willing to provide updated medical history in the future and whether she has preferences about future contact.
How to Find a Trusted Egg Donor Agency in the USA
A trusted egg donor agency should do far more than display attractive profiles. It should protect donor welfare, support intended parents, coordinate responsibly with clinics and attorneys, communicate transparently about costs, and follow ethical recruitment practices. Because egg donation is both emotionally sensitive and financially significant, choosing the right agency can make the difference between a well-managed journey and a stressful experience.
Start by looking for agencies with a clear history, professional leadership, transparent fees, realistic claims, and strong relationships with reputable fertility clinics. An agency does not need to be the largest to be trustworthy, but it should be organized, responsive, and honest about risks. Be cautious with agencies that guarantee success, pressure you to sign quickly, hide costs, or present donor compensation in a way that seems coercive.
| What to Evaluate | Signs of a Trusted Agency | Warning Signs |
|---|---|---|
| Transparency | Provides itemized fees, refund policies, and written timelines | Vague pricing, surprise fees, unclear payment deadlines |
| Screening standards | Requires medical, genetic, psychological, and background screening | Claims donors are “ready” without clinic confirmation |
| Ethical donor recruitment | Explains risks, consent, compensation, and donor rights clearly | Uses pressure tactics or focuses only on money |
| Clinic coordination | Communicates efficiently with IVF clinics and respects medical decisions | Gives medical advice outside its role or bypasses clinic requirements |
| Legal process | Requires independent attorneys and legal clearance before medications | Suggests legal contracts are optional or can wait |
| Communication | Responds promptly, documents decisions, explains next steps | Slow replies, inconsistent information, emotional pressure |
Before signing with an agency, ask direct questions. How are donors recruited? What screening is completed before a donor appears in the database? What screening happens after matching? Does the agency verify identity, education, and medical information? What happens if a donor fails screening? Are agency fees refundable or transferable to another donor? How long does matching typically take? Does the donor have previous cycle results? Who manages donor travel? Is there an escrow account? How are donor expenses reviewed and paid?
You should also ask about data security. Donor and intended parent information is deeply personal. A professional agency should have privacy policies, secure communication practices, and clear rules about who can access profiles. If adult photos, childhood photos, medical history, and personal essays are shared, the agency should treat that information with care.
Reviews can be helpful but should not be the only factor. Fertility journeys are emotional, and online reviews may reflect individual circumstances that are not fully visible. Instead, combine reviews with consultation calls, clinic recommendations, attorney feedback, and your own sense of whether the agency communicates respectfully.
Fresh Donor vs. Frozen Donor Eggs: Which Is Better?
There is no single best option for everyone. Fresh donor cycles and frozen donor eggs each have advantages. The right choice depends on budget, timeline, family-building goals, clinic experience, and risk tolerance.
Fresh cycles may be preferred when intended parents want the possibility of a larger number of eggs and embryos. This can be valuable for those hoping for more than one child. Fresh donation may also allow more direct coordination with donor testing and sperm matching. However, it usually costs more, takes longer, and carries the risk that the donor may not respond as expected or may withdraw before retrieval.
Frozen donor eggs may be preferred when intended parents want a faster, more predictable process. The donor has already completed retrieval, and the eggs are already available. Costs may be easier to estimate. However, the number of eggs is limited, and not every egg will survive thaw, fertilize, develop into a blastocyst, or become a healthy pregnancy. It is important to ask whether the egg bank offers any guarantee, such as a minimum number of mature eggs, thaw survival, blastocyst development, or replacement lot under specific conditions.
If you are choosing frozen eggs, ask how many eggs are included, whether they are mature eggs, what the donor’s age was at retrieval, what genetic screening was performed, what infectious disease testing was completed, and whether the eggs can be shipped safely to your clinic. If choosing a fresh donor, ask whether the donor has donated before, how many eggs were retrieved in prior cycles, whether pregnancies resulted, and whether she completed the process reliably.
Medical Risks and Safety for Egg Donors
Egg donation is generally considered safe when performed by experienced fertility specialists, but it is not risk-free. Donors take injectable hormone medications to stimulate the ovaries and undergo a transvaginal egg retrieval under sedation or anesthesia. Short-term side effects may include bloating, mood changes, injection-site discomfort, pelvic pressure, fatigue, and cramping after retrieval.
A rare but important risk is ovarian hyperstimulation syndrome, or OHSS, in which the ovaries become swollen and fluid shifts in the body. Modern protocols have reduced the risk of severe OHSS, especially with careful monitoring and the use of safer trigger medications when appropriate. Other rare risks include bleeding, infection, ovarian torsion, anesthesia complications, or injury to nearby structures during retrieval.
Ethical agencies and clinics should explain these risks clearly to donors. Donors should never feel rushed or pressured. They should have access to medical professionals, know whom to call after retrieval, and receive clear instructions about activity restrictions. Intended parents should care about donor safety not only for ethical reasons, but also because a well-managed donor cycle is more likely to proceed smoothly.
What Intended Parents Should Look for in a Donor Profile
Donor profiles can be emotionally powerful. Intended parents may naturally focus on appearance, ethnicity, education, talents, personality, or resemblance to the intended mother. These preferences are valid, but medical and genetic information should be weighed carefully. A beautiful profile does not replace strong screening.
Important profile elements include the donor’s age, height, weight, ethnicity, education, occupation, reproductive history, prior donation history, AMH or other ovarian reserve markers if available, family medical history, genetic carrier screening results, personal health history, medications, mental health history, and lifestyle factors. If the donor has children, that may provide some reassurance about fertility, but donors without children can also be excellent candidates.
Genetic carrier screening deserves special attention. Most people carry at least one recessive genetic variant. This does not usually affect their own health, but if both the egg donor and sperm provider carry variants in the same gene, there may be an increased risk of an affected child. A genetic counselor can help interpret results and determine whether a donor is a compatible match.
Intended parents should also consider future identity questions. Does the donor agree to release identifying information when the child becomes an adult? Is she open to future contact through the agency? Will the agency maintain updated contact information? Does the donor understand that DNA testing may make permanent anonymity impossible? These questions are increasingly important in modern donor conception.
Insurance and Financing Options
Insurance coverage for donor egg IVF in the USA is inconsistent. Some employer-sponsored plans cover fertility testing or IVF but exclude donor eggs. Others cover medications, embryo transfer, or diagnostic services but not donor compensation or agency fees. A few states have fertility insurance mandates, but even in mandated states, coverage details vary by employer size, plan type, diagnosis, and exclusions.
Before beginning, intended parents should request a written benefits verification from their insurance provider and fertility clinic. Ask specifically about donor egg IVF, donor screening, recipient monitoring, medications, embryo freezing, PGT-A, sperm procedures, and storage. Do not assume that “IVF coverage” includes donor eggs.
Financing options may include clinic payment plans, fertility loans, health savings accounts, flexible spending accounts, employer fertility benefits, grants, and package programs. Some intended parents compare domestic donor egg treatment with treatment abroad, where costs may be lower. However, cross-border care involves legal, logistical, donor anonymity, and regulatory differences, so it should be evaluated carefully.
Questions to Ask Before You Commit
A good decision begins with good questions. Before choosing an egg donor, clinic, agency, or egg bank, intended parents should gather written answers whenever possible.
- What is the total estimated cost, including agency, clinic, medications, legal, travel, storage, and testing?
- Which fees are refundable, non-refundable, or transferable if the donor is disqualified?
- What screening has already been completed, and what remains to be done?
- Does the donor have previous cycle results, including eggs retrieved, mature eggs, fertilization rate, blastocyst development, and pregnancy outcomes?
- What genetic carrier screening panel was used, and has the sperm source been tested with a compatible panel?
- What are the clinic’s live birth rates for donor egg IVF, not just general IVF?
- What is the clinic’s recommendation regarding single embryo transfer?
- How are unused embryos handled, stored, donated, or discarded according to the legal agreement?
- What type of donor identity arrangement is available: anonymous, semi-open, open, or identity-release?
- Who will provide independent legal representation for the donor and intended parents?
- How will future medical updates be shared between the donor and the family?
Common Mistakes to Avoid
One common mistake is choosing a donor based only on appearance or academic background while overlooking medical history, genetic compatibility, and availability. Another mistake is comparing agencies only by price. A low agency fee may not include important services, and a high fee does not automatically guarantee quality. What matters is transparency, professionalism, screening, and support.
Some intended parents also underestimate the emotional side of donor eggs. For a woman who expected to use her own eggs, moving to donor eggs may involve grief, relief, hope, and uncertainty all at once. Counseling can be extremely helpful. Using donor eggs does not make a parent less real, but it may require time to process the genetic difference and think about how to share the child’s story with confidence.
Another mistake is failing to plan for future siblings. If you hope to have more than one child, discuss embryo numbers, donor availability, and storage early. Waiting several years may mean the donor is no longer available. Frozen embryos from one cycle can offer continuity, but only if enough embryos are created and stored.
Finally, do not skip legal work. Even if the donor is a close friend or family member, legal clarity protects everyone. A known donor arrangement without a strong legal agreement can create confusion about expectations, boundaries, privacy, and future involvement.
A Practical Comparison of Options
| Option | Best For | Potential Advantages | Potential Drawbacks |
|---|---|---|---|
| Fresh agency donor | Families wanting more eggs or future siblings | Larger potential egg yield, customized match, fresh cycle data | Higher cost, longer timeline, risk of donor cancellation or poor response |
| Frozen donor eggs | Families seeking speed and predictable logistics | Eggs available now, simpler scheduling, often lower cost | Limited egg number, thaw and embryo development uncertainty |
| Known donor | Families who value genetic or personal connection | Known background, possible ongoing relationship, personal meaning | Emotional complexity, boundary issues, still requires full screening and legal work |
| Clinic in-house donor program | Patients who prefer integrated care | Streamlined coordination, clinic-controlled screening | Smaller donor pool, less flexibility in some programs |
Final Thoughts
Using an egg donor in the USA offers a highly effective path to parenthood for many people who cannot use their own eggs or who need donor eggs as part of a broader family-building plan. The country has advanced fertility clinics, experienced laboratories, established donor agencies, and strong legal resources. Yet the process requires careful planning because costs are substantial, success rates vary, and ethical screening matters.
A realistic budget should include more than donor compensation. It should account for agency fees, medical care, medications, screening, legal contracts, psychological evaluation, travel, embryo freezing, storage, and possible additional transfers. A realistic success discussion should focus on live birth rates, cumulative outcomes, donor history, sperm quality, lab performance, and uterine readiness rather than simple promises.
The best agency or egg bank is not necessarily the one with the largest database or the most polished profiles. It is the one that communicates clearly, protects donors, supports intended parents, follows medical and legal best practices, and is honest about both possibilities and limits. With the right team and thoughtful preparation, donor egg IVF can be a hopeful, ethical, and medically sound route to building the family you have been waiting for.
