Egg Donor Program for Recipients

The UCSF Egg Donor Program began in 1991 and was one of the first donor egg programs in the San Francisco Bay Area.  Egg donation is a method that allows couples to become parents when the woman is unable to successfully conceive using her own eggs.  The UCSF Egg Donor Program helps over one hundred couples achieve their goal of becoming parents each year. Initiating the process of having a baby through egg donation may seem complicated at first, but take comfort in knowing that our experienced physicians, nurses, and counselors will guide you step-by-step through the entire process. 

Donor Eggs: A Valuable Option

An increasing number of women are choosing egg donation when other traditional infertility therapies have been unsuccessful or when hormonal tests indicate very poor reproductive potential.  Using an egg donor may also be appropriate for a woman whose ovaries were absent at birth or were removed or damaged by surgery, chemotherapy and/or radiation.  Finally, it can be an option for patients who would like to eliminate the risk of passing on a known genetic condition carried by the female partner. 

Because the chance of achieving a live birth is strongly related to the age of the egg, using donor eggs can often substantially increase the likelihood of having a baby from IVF.  At UCSF, the chance of achieving a live birth from a single egg donation cycle is greater than 60%. Furthermore, because many cycles using donated eggs result in surplus embryos to freeze, the cumulative pregnancy rate including subsequent frozen embryo cycles is approximately 80% at our center.

Having a baby using a donor egg provides couples with the opportunity to experience pregnancy, childbirth, and breastfeeding, and to have a child who is genetically connected to the father.  You and your partner will have control over many aspects of the process, including when to try to become pregnant and the choice of the donor.

Choosing a Donor

An important step in the egg donation process is choosing a donor.  At UCSF, we respect that the process of determining the right donor is a uniquely personal decision.  We have several resources, including a psychologist with expertise in fertility and family building, to assist in the decision-making process. There are two basic types of egg donors:

Known Donors

Known donors are most commonly sisters, but also can be cousins, nieces, friends, and sometimes acquaintances. Known donors must pass minimum screening criteria. They may be compensated or non-compensated.

Recruited Donors

Recruited donors are usually young women with excellent reproductive potential who are compensated for their time and efforts in assisting other patients in becoming pregnant.  Recruited donors may be found through egg donor agencies or through the UCSF Center for Reproductive Health in-house Egg Donor Program.

Using a Donor from the UCSF Center for Reproductive Health Donor Program

The team at UCSF recruits and screens a pool of in-house donors who are available for selection by our patients.  The cornerstone of our program is our highly selective comprehensive screening process.  In recruiting and screening donors, we adhere to the guidelines from the American Society for Reproductive Medicine, the United States Food and Drug administration, and to our own institutional ethics board.  Our donors are recruited and screened by our egg donor screening team, including Dr. Huddleston, reproductive endocrinologist, Dr. Pasch, clinical psychologist, Gina Davis, certified genetic counselor, and our donor egg coordinators.  In most cases, donors become available only after their screening has been fully completed and candidates have been designated as eligible according to all our guidelines. This includes full review of medical history, physical examination, genetic and mental health screening, and testing for infectious disease. 

There are several benefits of choosing a donor from our pool. We have a highly selective comprehensive screening process. Our multidisciplinary team that includes a physician, psychologist and genetic counselor work together to ensure that donors in our pool are fully eligible. This means that you are unlikely to experience the disappointment of carefully choosing a donor from an agency only to find out they are ineligible once they are medically screened. Additionally, you will have the ease and simplicity of working closely with one center for all of your needs during the egg donation cycle. Finally, using a donor from our pool is often more economical than working with an agency because there are no extra agency fees to pay.

Choosing a Donor from an Outside Agency

We work collaboratively with many outside egg donor agencies. Outside agencies recruit and partially screen donors. The agency then assists couples in identifying possible donor matches from within their pool.  We are happy to assist you in coordinating a donor egg cycle with a donor from an outside agency.  One benefit of using an outside agency is the overall larger pool available to you.  Because there are many agencies in the Bay Area, couples may find donors meeting their own specific criteria more efficiently by working with an agency.   

If you are interested in using a donor from an outside donor agency, we will provide you with a list of donor agencies in the area.  We recommend that you ask the agency about their policies and procedures for recruitment and screening directly.  Donors from outside agencies must have a mental health screening arranged through the agency and must meet specific criteria for eligibility, such as recent infectious disease screening, to proceed with a cycle within our center. Once selected, the donor will undergo an exam performed by physicians in our office prior to cycle planning. 

The Process


A first step for prospective patients is to consult with one of our reproductive endocrinologists who will perform an evaluation and then discuss the various treatment strategies available to you.  Our physicians strive to help guide you in understanding all aspects of the options available.   If you decide to proceed with a donor oocyte cycle, your physician will discuss what is required to prepare for your cycle.  Your physician will perform a medical evaluation and physical examination to ensure that your health would not be jeopardized by pregnancy.

Cycle Preparation

To optimize the success of a donor egg cycle, your physician will order several tests that seek to identify and correct any abnormalities that could interfere with fertilization and/or implantation. These tests include a detailed semen analysis, a saline sonogram (a test which evaluates the uterine cavity) and basic blood work evaluating blood count, blood type and thyroid function.  In consideration of your overall health, we also require that you are up to date on recommended health screening, such as the pap smear and mammogram (if over 40).

Though women achieve high success rates with egg donation throughout their 40s, the risks during pregnancy increase as age approaches 50.  If you are 45 or greater, additional testing is recommended to ensure that you enter your pregnancy in optimal physical condition. This testing includes a screen for diabetes, an EKG and clearance by a perinatologist (high-risk obstetrician). 
As part of preparation for the cycle, you will also meet with our psychologist to discuss your plans for egg donation and to review the various decisions you will face now as you go through the process and in the future once you have a child born from egg donation.

Donor Selection

UCSF Donors

If you are working with the UCSF Egg Donor Program, our egg donor coordinator will arrange a time for you to view profiles of our donor candidates.  You will have access to information about the donor’s background, medical history, educational level, and family history. You will also have the option of viewing photographs of prospective donors.   We will discuss with you any relevant findings from the screening process itself, including genetic screening and testing, mental health screening, infectious disease results, and physical findings. 

Once you have chosen a donor, the donor coordinator will confirm with the donor candidate that she is free for donation during the time period requested. Once the donor selection process is complete, information about your donor will be given to your physician and nurse coordinator, and your cycle will be arranged.

Agency Donors

If you select a donor from an outside agency, the agency will send information about the donor to our office for cycle coordination.


It is important for the donor and recipient to be synchronized so that the recipient’s uterine lining will be ready for implantation at the same  time the donor’s eggs are retrieved and fertilized. This is usually accomplished by administration of birth control pills to synchronize the egg donor and recipient’s cycles. When the cycles are synchronized, the donor is instructed to take the medications to stimulate the growth and maturation of a cohort of eggs, and is monitored by ultrasound and blood tests over the course of 10-14 days, until the eggs are ready for egg retrieval. Meanwhile, the recipient will be taking different medication to prepare the uterine lining for implantation of the embryos.

Egg Retrieval and Embryo Transfer

Once the donor’s eggs reach the point of maturity, an egg retrieval is scheduled. The recipient’s partner or sperm donor will need to provide a sperm sample on the day of the egg retrieval for insemination of the eggs. When the embryos reach the proper stage for transfer, usually day 3, the recipient will return to the clinic for transfer to the uterus. We typically recommend the transfer of one or two embryos from donor cycles. The decision regarding how many embryos to transfer will be discussed in detail with you by your physician. The transfer of a single embryo will reduce the risk of a twin gestation.  Additional high quality embryos that are available from the cycle can be frozen and preserved for their use at another time.
