Infertility due to various reasons, now is not a verdict for a woman. Now, thanks to medical advances for many women there is an opportunity to conceive, carry and give birth to a healthy baby.
Donor eggs are used in treatments that are quite expensive. The price is justified, by the careful and comprehensive selection of donor eggs, and their medical examination and the subsequent reward to the donors. Such a complicated procedure for in vitro fertilization using donor eggs allows many couples to have long-awaited children. According to numerous studies the probability of pregnancy in the program with donor eggs is 60-65%.
Today, modern technology can keep the egg safe by quickly freezing it. In the future this practice will help setting up donor eggs banks, keep them for a long time, and arrange quarantine for six months in order to more carefully examine the donor for infection.
This method of fertilization reserved for women with the following pathologies:
- Do not have ovaries (from birth or after surgeries);
- Not having a uterus;
- With the syndrome of the premature termination of ovarian function;
- No eggs due to menopause;
- If the stimulation by hormones is contraindicated;
- With severe genetic disease;
- After several unsuccessful attempts at IVF.
Contraindications to implanting an donor egg are similar to those with IVF, namely:
- Organic or mental illness;
- Congenital malformations, in which the embryo cannot be implanted and child bearing is not shown;
- Tumors of the ovary or the uterus;
- Acute inflammation of the reproductive organs.
Who can become an egg donor? Anonymity is guaranteed. As an egg donor can be a women of 20-35 years who already gave birth to healthy children. Such women may not have plans to have additional children. A woman should not have any hereditary diseases and malformations. Before any eggs are donated a woman has to undergo a medical examination (physician, psychiatrist, genetics), she’ll be tested for AIDS and sexually transmitted diseases. She must also sign a document waiving her rights to her egg and or subsequent child that can be born from fertilizing her egg.
The entire process of fertilization, the donor egg, is being conducted in several stages. Here is a simple example:
- Selection and screening donors;
- Stimulation of production of eggs from a donor with hormones. The patient and the donor undergo synchronization of cycles. As this type of simulation is associated with some risk for future pregnancies, women that no longer are planning to have additional children often selected as donors;
- Egg collection takes place under general anesthesia. Extraction takes place through a puncture of the abdominal wall or vagina;
- The egg is fertilized with sperm of patient’s husband;
- The resulting embryo is implanted into the patient's uterus on 3 or 5 day;
- Growth and development of the embryo is closely controlled and monitored;
