Oocyte donation: clinical and practical aspects.
Oocyte donation is an effective treatment modality for women lacking functioning ovaries, but also for women in whom repetitive in-vitro fertilization (IVF) cycles did not result in the development of adequate number of oocytes as well as for those at risk of transmitting genetic diseases. In women with ovarian failure, artificial menstrual cycles are required in order to produce endometrial growth and differentiation similar to that in women with normal ovarian function. Synchronization of donor's and recipient's cycles is mandatory, since the window of implantation is rather limited. The excellent results of oocyte donation treatment confirm that this assisted reproduction technique can provide a novel approach for the treatment of infertility in these groups of patients. Nevertheless, pregnancies in women of advanced reproductive age are associated with significantly more obstetrical complications and higher perinatal morbidity and mortality rates. Furthermore, aging parents have considerably higher chances to develop serious or life-threatening diseases. Thus, careful medical screening and extensive counselling is mandatory, taking into account the psychosocial ramifications of the procedure and, especially, the best interest of the child-to-be.
