Donor Egg & Embryo

Building a family is deeply personal. For some individuals and couples, using a donor egg or donor embryo provides a safe and effective pathway to pregnancy when other treatments have not been successful. Our experienced fertility team will guide you step by step through every stage of the journey—from understanding your options to selecting the right donor and preparing for treatment—with sensitivity, clarity, and support.

What is a Donor Egg?

Donor egg treatment involves using eggs from another woman (the donor) to achieve pregnancy. The donor undergoes ovarian stimulation and egg retrieval. The eggs are fertilised with sperm through IVF, and the resulting embryo is transferred into the recipient’s uterus.

The recipient carries the pregnancy and gives birth, even though the egg is genetically linked to the donor rather than the recipient.

Who is Suitable for Donor Egg Treatment?

Donor egg treatment may be suitable for:

• Women with diminished ovarian reserve: Very low egg numbers or poor egg quality
• Premature ovarian insufficiency or early menopause
• Women over 40 with significantly reduced egg quality
• Women with repeated IVF failure using their own eggs
• Women with genetic conditions they do not wish to pass on
• Women who have undergone cancer treatment affecting ovarian function
• Single men or same-sex male couples using a gestational carrier

A comprehensive fertility assessment is performed to ensure this is the most appropriate pathway.

Benefits of Donor Egg Treatment

• Higher Success Rates: Donor eggs typically come from younger women, improving embryo quality and implantation rates
• Genetic Screening Options: Donors undergo extensive medical and genetic screening
• Pregnancy Experience: The recipient carries and gives birth to the child
• Expanded Family Options: Enables parenthood when using own eggs is not viable

For many women, donor egg IVF offers significantly higher success rates compared to IVF using their own eggs at advanced reproductive age.

The Process of Using a Donor Egg

Our fertility team provides personalised guidance throughout the process.

Donor Selection

• Anonymous or Known Donor: Donors may be anonymous through a licensed egg bank or known to the recipient
• Comprehensive Screening: Medical, genetic, psychological and infectious disease screening
• Matching Process: Physical traits, medical history, education, values and background may be considered

Our experienced team works closely with patients to help them select the right donor aligned with their preferences and values.

Cycle Preparation

• The recipient undergoes hormone therapy to prepare the uterine lining
• In some cases, cycles are synchronised; in others, frozen donor eggs are used

Egg Retrieval & Fertilisation

• Donor receives stimulation medication
• Eggs are retrieved via a transvaginal ultrasound-guided procedure
• Eggs are fertilised with partner sperm or donor sperm
• Embryos are cultured for several days

Preimplantation Genetic Testing (PGT) may be offered where appropriate.

Embryo Transfer

• One embryo (sometimes two) is transferred into the recipient’s uterus
• The procedure is simple and does not require anaesthesia

Pregnancy Testing

• Blood test approximately 10–14 days later

Donor Egg Risks and Considerations

• Medical Risks (Donor): Ovarian hyperstimulation, bleeding, infection (rare)
• Medication Side Effects (Recipient): Bloating, mood changes, breast tenderness
• Multiple Pregnancy Risk: Reduced with single embryo transfer
• Emotional Considerations: Identity, genetic connection and disclosure decisions
• Legal Framework: Regulations vary; counselling and legal advice are recommended

Emotional and Psychological Support

Using a donor egg can raise complex emotions. We strongly recommend fertility counselling before treatment. Discussions may include:

• Disclosure to future children
• Relationship dynamics
• Cultural and ethical considerations
• Expectations and boundaries if using a known donor

Our multidisciplinary team provides compassionate support throughout the process.

What is a Donor Embryo?

Donor embryo treatment involves transferring an embryo created by another individual or couple who have completed their IVF treatment and chosen to donate remaining embryos.

In this case, the embryo is genetically related to the original egg and sperm donors—not the recipient.

Who is Suitable for Donor Embryo Treatment?

Donor embryo treatment may be suitable for:

• Couples where both partners have fertility issues
• Women without viable eggs and no partner sperm available
• Women with premature ovarian failure or menopause
• Individuals with serious genetic conditions
• Single men or same-sex male couples using a gestational carrier
• Patients seeking a lower-cost alternative to dual gamete donation

Benefits of Donor Embryo Treatment

• Opportunity to Experience Pregnancy
• Often More Cost-Effective than Separate Egg & Sperm Donation
• Embryos Often Already Frozen and Available
• Pre-screened for Infectious Diseases and Often Genetic Conditions

Success rates largely depend on the age of the egg donor at the time of embryo creation.

The Process of Using a Donor Embryo

Embryo Selection

• Anonymous or occasionally known donation
• Review of donor medical and family history
• Infectious disease screening compliance

Recipient Preparation

• Hormonal preparation of the uterine lining
• Monitoring via ultrasound and blood tests

Embryo Transfer

• Frozen embryo is thawed
• Simple transfer procedure
• No surgery required

Pregnancy Testing

• Blood test approximately two weeks after transfer

Donor Embryo Risks and Considerations

• Hormone medication side effects
• Small procedural risks
• Emotional considerations regarding the genetic link
• Disclosure decisions
• Legal and ethical regulations

Professional counselling is strongly recommended before proceeding.

Implications of Donor Embryo Use

• No Genetic Link to Recipient or Partner
• Importance of Transparency Planning
• Long-Term Family Considerations

Many families benefit from early, age-appropriate disclosure practices supported by counselling.
