Oocyte donation in patients without ovarian function.

The clinical, hormonal and cytogenetic findings in 36 women with primary ovarian failure, referred for oocyte or embryo donations are reported. Fifteen women were suffering from ovarian dysgenesis and 11 from premature menopause. Six of these 26 patients showed X-chromosome abnormalities. One patient had a Noonan syndrome. The remaining 10 had surgical menopause. The mean duration of their infertility was 6.5 +/- 3.2 years (+/- SD). All patients had elevated serum gonadotrophins within the menopausal range. Hypothalamic, pituitary and thyroid function were found to be intact. In one of the 15 ovarian biopsies on the patients with chromosomal competent ovarian failure, primordial follicles were found. Hysterosalpingograms revealed a normal uterine cavity in all patients. In view of oocyte donation, careful evaluation of the obstetric risk was mandatory in the six patients with X-chromosome aberrations and in the patient with the Noonan syndrome, because of their short stature and possible concomitant cardiovascular and renal disease. After substitution therapy with oestradiol valerate and natural progesterone, 13 pregnancies were established, seven patients delivered (one set of twins), eight healthy children were born, three pregnancies aborted and three pregnancies are progressing normally.
