Among the possibilities of sterility therapy by means of assisted reproduction methods is also oocyte donation. The oocytes retrieved from an anonymus donor are fertilized by the recipient's partner sperm and the arisen embryos are then transferred to the recipient's (future mother) uterus.
For whom is egg (oocyte) donation intended?
Couples where the woman does not produce her own oocytes
Most frequently this group covers women with undeveloped ovaries, or women having both ovaries removed during surgery. Women affected by an early failure of ovarian function also need donated eggs.
Couples where the woman does not produce oocytes of good quality
In this group women repeatedly underwent a sterility therapy by means of extracorporal fertilization by which either no ova of good quality were gained or no embryos of good quality arose. Also older women can produce ova of lower quality which are not capable of fertilizing or the nidation of arisen embryos in uterus is impossible.
Couples where the woman is a carrier of a hereditary disease
In these women the genetic examination showed a chromozomal change which could be transferred to future offspring.
In all these women the acceptance of donated oocyte is the only way of becoming a mother.
The modern method of oocyte donation is possible only thanks to women who become voluntary donors because they want to help other women to reach what they desire most - to have a child.
Since 1983 when the oocyte donation was successfully performed for the first time this method has been used in a greater extent and in connection with the development of the assisted reproduction the oocyte donation is an excellent success.
In our clinic within the oocyte donation programme the highest standards and criteria stipulated by The American Society of Reproductive Medicine (ASRM) are used.
The success rate in oocyte donation programme is about 65% of pregnancies for an embryo transfer.
The risk of miscarriage in the oocyte donation programme is about 10 -15%,
The number of extrauterine pregnancies is about 1.2%
The number of multiple pregnancies is about 20%.
In our clinic 1-3 embryos are usually inserted.
