Oocyte donation is procedure in which women above age 21 years  voluntarily give their oocytes for  the advanced fertility treatment of another woman or for research. The procedure typically involves a doctor removing a eggs from the donor, fertilizing them in a laboratory, and then transferring the resulting embryos into the recipient’s uterus. Oocyte donation can be used to treat infertility in women who cannot use their own eggs for various reasons, including ovarian failure, avoiding congenital anomalies in the fetus, or advanced age. The practice and policy of oocyte donation, especially in relation to donor compensation, anonymity and disclosure to donor-conceived children, differ across the globe based on the regulatory framework, ethics principles and local beliefs of the respective country. The success rate of oocyte donation varies depending on factors such as age and cause of infertility.
