Donor egg is recommended for couples unable to conceive with their own eggs. Success rates with egg donation are comparatively higher.
Who can donate eggs
- A woman who is below 35 years of age and has had a normal conception earlier with no history of recurrent miscarriages.
- A normal harmonal profile by blood tests.
- An anatomically normal pelvic reproductive tract through ultrasound scans.
We would also share pertinent information with you, which includes her religion, marital status, age, complexion and so on.
Scenarios where donor egg is used:
- Premature ovarian failure (early menopause)
- Patient who had their ovaries removed (oophorectomy)
- Patients who underwent radiotherapy for cancer.
- Very poor egg quality
- Poor response to ovarian stimulation
- Repeated IVF failures with own egg
- High chances of chromosomal abnormalities in babies
- High day 3 follicle stimulating hormone (FSH) levels
- Very low antral follicle counts on ultrasound
- Advanced female age, such as over age 40
Process of a egg donation cycle
An appropriate egg donor is chosen by the couple and thoroughly screened for infectious diseases and genetically transmissible conditions. Donors can be known or anonymous to the couple.
Appropriate consents are signed by all parties. The donor is stimulated with gonadotropins to develop multiple eggs.
Once several follicles are matured , all the eggs are collected.
After fertilization with the husband’s sperm (or donor sperm) the embryos are incubated for either 3 or 5 days depending on the type of transfer.
Concurrently , the recipient woman is placed on medication to stimulate a healthy uterine lining.
Once the endometrium (uterine lining) is ready with the “triple line” , then the Embryo transfer process is initiated.
This process of timing the ICSI / IVF , developing the uterine lining in the recipient and embryo development in the lab requires sufficient skill and experience for a successful implantation.
Embryo transfer calendar for recipient
Success rates of oocyte donor cycle:
- Success rates using donor eggs depends on
- The age of the donor,
- The egg quantity and quality,
- The number of embryos transferred,
- The quality of the recipient’s uterine lining,
- The experience of the clinician
- The center where the procedure is done.
