Informing the Receiver Couple
Information regarding the medical procedure of egg transplant should be given, and the questions of the couple participating in the program should be answered in a clear and correct way by their doctor. Before the procedure signed approval of the couple should be received regarding the fact that they accept the process.
Follow-up of the Couples who have decided to carry out the Oocyte Donation
Following the examination and tests completed by your doctor, microinjection and embryo transfer phases will be commenced in the pre-determined period that your doctor will inform you about.
Physical characteristics of the egg donor such as skin colour, eye colour, hair colour and body structure are chosen in a way that they shall be similar to those of receiver couple as far as possible. Additionally, ethnic origin, blood group, and other physical characteristics are matched similarly as far as possible.
Results of the Treatment
At present, excellent pregnancy rates are obtained thanks to gamete donation; these rates are higher than the pregnancy rates obtained with the couples’ own eggs and sperms. The reason for this is thought to be the young age of the egg donor and producing higher quality eggs when compared to the infertile patients. In addition, endometrium of the receiver is not exposed to the hyperstimulation and can be more appropriate for the implantation. In this application, approximately 75% pregnancy rate can be achieved.
Stages of the Process
Stage 1: Egg Donor Matching
The couple interested in egg transfer is matched with the most appropriate anonymous egg donor based on physical characteristics. The clinic’s medical team performs this.
Stage 2: Egg Donor Preparation
The egg donor goes through ovarian stimulation and is synchronized with the receiver’s cycle.
Stage 3: Recipient Preparation
The endometrium of the recipient is prepared for embryo implantation via medication.
Stage 4: Oocyte Pick-Up (OPU) from the Egg Donor
When the egg donor is ready for OPU, the egg retrieval is performed.
Stage 5: Fertilization and Embryo Transfer
The collected eggs are fertilized with sperm, and the best embryos are transferred back to the recipient going through egg transplant. Any excess embryos can be frozen for future use.
Stage 6: Pregnancy test
The recipient going through the treatment is tested for pregnancy usually 11 days after embryo transfer.
