Using a Sister, Friend, or Known Donor: What You Need to Know

Egg donation is a deeply personal decision, and many intended parents wonder if they should consider using a known egg donor—such as a sister, friend, or someone they already trust. Unlike anonymous donation, this pathway adds layers of emotional, legal, and relational complexity. Yet, for many, the possibility of maintaining a genetic relationship in egg donation feels meaningful and worth exploring.

Dr. Minoos Hosseinzadeh, Founder and Medical Director at Fertility Institute of San Diego and EggDonorsSanDiego.com, explains: “When families explore using a sister or friend as their egg donor, the journey is often guided by trust and shared values. But medical, legal, and emotional safeguards are absolutely essential to ensure the process is both ethical and sustainable.”

How the Known Donor Process Works

The known egg donor process begins much like traditional egg donation. The donor undergoes comprehensive medical, genetic, and psychological screening to ensure she is a safe and healthy candidate.

Steps typically include:

• Medical screening for egg donors: hormone testing, ultrasounds, infectious disease screening
• Genetic testing: evaluating hereditary risk factors
• Psychological counseling for egg donation: preparing both donor and recipient for the emotional dynamics
• Legal contracts: establishing boundaries and rights through known donor agreements

Why Families Consider a Known Donor

There are several reasons intended parents might consider using a known egg donor:

• Desire for a genetic link within the family (e.g., a sister as egg donor)
• Emotional trust and comfort when the donor is a close friend
• Transparency about medical history and long-term health
• Reduced uncertainty compared to an anonymous donor

Dr. Hosseinzadeh adds: “Known donation can be profoundly rewarding, but it is not without challenges. Family dynamics, donor-recipient relationship boundaries, and future expectations must all be openly discussed.”

Who Might Choose a Sister, Friend, or Known Donor?

• Couples or individuals seeking a sibling genetic connection
• LGBTQ+ families who want a donor within their community
• Single parents by choice who value transparency over anonymity
• Families with limited access to anonymous donor databases

When to Involve Professionals

Because this process involves nuanced legal and emotional layers, it’s important to engage professionals early. Fertility clinics, attorneys, and counselors help ensure that all parties understand expectations and obligations. Without legal safeguards, risks of using a known donor may include custody disputes, blurred family roles, or complications in future relationships.

Emotional Implications of Egg Donation

Using a sister or friend as an egg donor often raises profound emotional considerations.

• Donor perspective: balancing generosity with personal boundaries
• Recipient perspective: managing gratitude, guilt, or pressure
• Future child perspective: understanding their genetic origins in a clear, healthy way

Dr. Hosseinzadeh emphasizes: “We encourage psychological counseling for every known donor arrangement. It ensures that future conversations—particularly with the child—are built on honesty and emotional readiness.”

Risks and Complications

While medically safe under clinical oversight, known donation still carries risks:

• Complications from ovarian stimulation and egg retrieval
• Strained family or friend relationships if boundaries are unclear
• Emotional fallout if treatment is unsuccessful

Prevention and Boundaries

Establishing donor-recipient relationship boundaries is critical. This includes discussing:

• Future contact and involvement in the child’s life
• Confidentiality and privacy preferences
• Financial responsibilities and coverage of donor medical costs

Types of Treatment Available

When using a known egg donor, treatment options include:

• IVF with the donor’s eggs and recipient’s partner’s sperm
• IVF with donor eggs and donor sperm for LGBTQ+ couples or single parents
• Surrogacy combined with a known egg donor for intended parents who cannot carry a pregnancy

Costs of Using a Known Donor

While compensation may not apply when the donor is a friend or sister, costs remain for:

• Fertility clinic egg donor requirements (screenings, medications, procedures)
• Attorney fees for drafting known donor agreements
• Counseling sessions for both donor and recipient
• IVF cycle expenses and possible surrogacy involvement

For some families, costs are lower compared to anonymous donors, but they must budget for comprehensive safeguards.
