Egg donation
This involves stimulating the ovaries of a female donor with fertility medicines, and collecting the eggs which form. The eggs are mixed with and fertilized by sperm of the recipient’s partner (similar to IVF). After 2-3 days, embryos are placed in the womb of the recipient via the cervix. This method is an option for women who have ovarian failure and cannot produce eggs; who have had their ovaries removed; who have conditions where the ovaries do not work (for example, in Turner syndrome) and where there is a high risk of transmitting a genetic disorder to the baby. It is also used in certain cases of IVF failure.
