Some or all of these tests may be required
Once donors are accepted into the program, they are placed into categories based on the criteria listed below. These criteria are used to make the closest match between the donor and recipient.
- Blood Type
- Skin colour
- Eye colour
- Hair Color
- Education status
Egg collection does not reduce the oocytes available to the woman. The procedure does not affect the donor’s fertility and age of menopause onset. Her chances of achieving pregnancy will be no different after she donates her eggs.
Briefly, the donor goes through two main steps. The first prepares the ovaries to stimulate increased egg production, and the second is collecting those eggs that develop. The woman will start the drug regimen on the second or third day of menstruation. The eggs will be collected after approximately 8-12 days of stimulation. Egg collection marks the end of the donor’s role in the process. Her eggs will be inseminated by the sperm obtained from the recipient’s husband, and the resulting embryos will be transferred to the recipient’s uterus.
Preparation of the recipient:
If the recipient menstruates regularly, there are two methods to prepare her uterus. Either the recipient’s cycle is synchronised to that of the donor by using a combination of hormonal supplements, or they temporarily suppress the recipient’s ovulation. Doctors usually use GnRH analogue drug type for this purpose. After the woman has her period, she starts taking estrogen hormone orally; later, Progesterone is added on the day the eggs are collected. This way, the endometrium (uterine lining) acquires the necessary thickness for the embryo to implant.
Preliminary tests done before the procedure are summarised below.
Our centre may run the following tests on the recipient couple:
