For women;
• Women who have never had periods although specified as having healthy intrauterine mucous membrane,
• Women having lost their egg cells following a chemotheraphy or radiotheraphy; women having an operation in which their eggs are removed by surgical ways, or women suffering from early menopause with an unknown reason,
• Women for whom the previous trials ended ineffectively with no eggs obtained.
• Patients for whom the result of the FSH test performed on the 3rd day of the periods is 15 and more,
• Women for whom the previous trials of IVF ended ineffectively with no pregnancy obtained,
• Removing of the ovaries,
• Patients who experienced great tissue loss owing to some reasons such as ovary cyst operation,
• The fact that a genetic disease is present in the family.
• Egg donation treatment is considered in case that pregnancy is not obtained owing to the fact that a few number of eggs, or defected eggs are available in Test-tube Baby treatments.
Selecting the donators for egg donation
• The majority of egg donators performs this process for money, and they are paid certain wages.
• The egg donator may be anyone known by the couple, or someone they do not know at all.
• The egg donators are healthy individuals whose ages vary between 20 and 30 years
• The donators who have already given birth to healthy child are preferred.
• The donators shouldn't have any family history regarding hypophrenia.
• The donators who have any problem concerning hereditary diseases should be avoided.
The donators are examined with respect to infectious diseases (HIV, Hepatitis B and C, Cytomegalovirus, Syphilis, Chlamdydia) and genetic diseases (Karyotype analysis and Cystic Fibrosis analysis); and screened for Thalassemia and Sickle cell anemia (applicable for particular ethnic origins), whose blood types and Rh conditions are determined.
The physical characteristics of the egg donator, such as the skin color, eye color, hair color and the body type, are selected as similar to those of the couple as possible. Additionally, the ethnical origin, blood type and the other physical characteristics are selected as in concordance with the couple as possible.
The cycle of egg donation
Birth control pills are used in order to provide the coordination of periods between the egg donator and the receiver. The receiver is given estrojen on ascending doses as soon as the donator starts with the egg augmentation treatment. Estrogen makes the intrauterine layer thicker so that the retention of the transferred embryos is ensured. On the same day the eggs of the donator are collected, her partner's sperms are sampled and the fertilization process gets started. The receiver woman usually begins to use progsterone via vaginal route on the same day as egg collection process. Following the sperm sampling process, 2 or 3 embryos are transferred into the uterus within 3 or 5 days. The administration of progsterone and estrogen is maintained after the process of transfer. 12 days following the transfer process, the pregnancy result is found out by analysing the ßHCG in the blood.
Note:It is often the case in IVF with egg donation that more embryos are produced than can be used in one cycle. When this happens, those embryos can be frozen and preserved for future use.
Also note that for both menstruating women and menopausal women, the treatment stages are the same. Both must take medication prior to the embryo transfers.
The success rate in egg donation and the related countries
1. The countries where the eggs of healthy donators who are under 30 years old and who have already given birth have a success rate of 60-70%. (USA, Spain, TRNC-North Cyprus)
2. The success rate of the countries (Argentina, Belgium, USA, Southern Cyprus) in which the eggs of an average healthy women are used, is 40-45%.
3. The success rate of the countries using donators who have not given birth, but have a number of eggs in excess is 30-37% (Israel, England, India).
4. The countries in which frozen or waste eggs are used: Greece, Israel.
Egg injection is not performed on the ground of legal obligation in some European countries such as Italy and France.
The benefits and risks of egg donation
The rate of clinical pregnancy is approximately 70% per donaton cycle within experienced clinics. In all cases, egg donation treatment has a greater rate of success in comparison with the cycles in which the eggs of the respective woman are used. Egg donation may be an alternate for children adoption. In the respective process, not only the half genetic material of the embryo is obtained from the couple, but also the mother provides the carrier environment for the embryo. In this way, the possibility of having a healthier baby in enhanced by establishing control on the growth and development of the fetus. The mother experiences the pregnancy from beginning to end, and her affection towards her baby gets developed. These are not the characteristics of the process of child adoption.
Complications
Possible displacement of the embryos into the cervix, resulting in a lost embryo, or in the fallopian tubes, resulting in tubal (ectopic) pregnancy; multiple pregnancies. If IVF is successful, a normal pregnancy will be carried out. If IVF with ICSI results in an unsuccessful pregnancy or no pregnancy, different methods of IVF should be considered, such as Egg Donor IVF, Sperm Donor IVF or Embryo Donor IVF.
Pain Factor: The last step, transferring the embryo may cause mild bleeding and cramping.
Recovery: After the procedure, the patient should return home to rest for the remainder of the day, and should avoid strenuous activities for the next three days.
