From 1993 to 1995, 82 donors have permitted the retrieval of 810 oocytes allowing to obtain 411 embryos. 95 receiving couples have been included : 30 obtained a pregnancy, 7 abandoned and 38 are waiting for a transfer. The rate of pregnancies by transfer is superior to the one observed with the transfer of frozen embryos (40.5% versus 27%).
A study, in which 110 patients were screened by a psychoanalyst, included 69 recipients who chose non-anonymous oocyte donation, i.e. they received oocytes from a known donor, most frequently a sister or a close relative. Another 41 recipients received anonymous oocytes, but had to bring a donor. Psychological motivations for either choice are reported, and significant topics such as attitudes towards confidentiality and links to the child are compared. No specific psychopathology is reported at this stage. An additional study on children born by these techniques is ongoing.
