How Egg Donation is performed?
Egg donation consists of three stages;
1-Deciding that we have to use egg donation and making PRE-PREPARATION:
making required tests and getting reports for mother candidate (FSH, LH, Estradiol, Prolaktin on day 2 or 3 of menstrual bleeding, AMH on any day) and be sure that egg donation is needed. After this, starting to use some medicine to woman partner to refresh and strengthen the uterus and to man partner for inducing the quality of sperms. Donor is selected and bleeding time programing is performed for donor and mother candidate to start bleeding on same day. If the mother candidate is in menopause, bleeding is not required for her. (This stage takes 1 week - 1 month and can be performed in patients' country).
2-PREPARATION
on day 2 or 3 of bleeding (menstrual cycle, for both donor and mother candidate) in the month that couple decide to come for the treatment, making required extra tests to both women and start using some more medication like injections for inducing eggs in donor and some medicine for mother candidate for preparing the uterus for embryo. Generally this medication stage takes 10 days. If the mother candidate is in menopause, bleeding is not required for her (this stage takes nearly ten days and can be performed in patients' country). After 12 days (on 14. day of bleeding) couple must be in Cyprus for oocyte pick up (OPU, egg collecting).
3- OPERATION
this starts with oocyte pick up (egg collection) from donor and ends with embryo transfer on day 3 or 5 of embryo development to the uterus of mother candidate. The eggs that are collected from donor woman are fertilized with the father candidate sperms on OPU Day (Day 0). After 3 or 5 days, embryos are transferred to the uterus of mother candidate. After transfer operation , couples can return to their countries whenever they want (this stage takes 3-5 days and patients must be in Cyprus). On 12. day after transfer beta-HCG test in blood must be done for learning pregnancy is negative or positive.
