Abstract:
The prognosis of couples with recurrent miscarriage is controversial despite efforts made during this century to learn about the physiopathology and treatment of this troublesome condition. Here we present our experiences of employing oocyte donation in eight couples in whom the woman was a low responder to gonadotrophin stimulation and had a previous history of recurrent abortion with negative routine infertility work-up for repeated pregnancy loss. Patients were desensitized with gonadotrophin-releasing hormone analogues and supplemented with oestradiol valerate for a minimum of 15 days until oocytes were donated from in-vitro fertilization and fertile donors. Then, progesterone was added until day 100 of pregnancy. A total of 12 oocyte donation cycles were performed in these patients. Clinical pregnancy and delivery rates per cycle were 75.0 and 66.6% respectively. The delivery rate per patient was 85.7% in this series, and the miscarriage rate per cycle was 11.1%. The results of ovum donation compared favourably with low responders without a history of recurrent abortion undergoing this treatment during the study period. These results strongly suggest that the oocyte may be the origin of infertility in women with idiopathic recurrent miscarriages. In addition, the results question the role of maternal local and systemic factors in early recurrent pregnancy loss, as well as the paternal contribution to its aetiology.
