There are two ways of preparation for couples undergoing Sperm donation, the first is preparation via IUI (Intra Uterine Insemination) and the second is IVF method.
IUI method is when the female has her ovaries checked and is closely monitored to check the growth of the follicle and when ovulation is optimal. The follicle is then controlled with medication to trigger ovulation and approximately 36 hours after this the sperm is injected via the uterus into the fallopian tubes so fertilisation can occur naturally.
IVF method is when the female partner is prepared for egg collection with a series of hormonal injections to stimulate the ovaries to produce more than one follicle which then can be collected around the 12th day of the menstrual cycle. Once the eggs are collected the donor sperm is injected (ICSI) into individual eggs. Once injection of sperm has been carried they then fertilise into embryos, the embryos are monitored for development which is then followed by embryo transfer either 3 or 5 days later.
Genetic diagnosis of embryos may be performed in order to eliminate egg related risks (such as Down syndrome, Turner’s syndrome) in the sperm donation process if the age of the mother candidate is advanced. In this sense, PGD (pre-implantation genetic diagnosis) or CGH method, which is also the first and only performed in our centre in Cyprus, can be preferred.
