OOCYTE DONATION IN MENOPAUSAL WOMEN

Oocyte donation was performed by in-vitro fertilization and embryo tra nsfer in 82 women. The average age of the patients was 48 years (range 26-60), and 71 were over 40 years old, with an average follicle stimu lating hormone (FSH) value of 74 +/- 14 IU and oestradiol concentratio n of 30 +/- 9 pg/ml. Overall 32 clinical pregnancies were achieved, of which 21 reached term, three are ongoing, and eight were lost (six mi scarriages, one abruptio placentae, and one severe gestational protein uria hypertension in the second trimester). The 21 term pregnancies pr oduced 26 newborns; one patient who had had three embryos replaced del ivered triplets and three patients had twins. Before the embryo transf er was performed, the endometritum thickness was accurately determined by vaginal ultrasound probe. The highest number of implanted embryos was reached when the endometrium thickness was 9-12 mm.
