Is the difference in miscarriage rates between menotropin-induced and natural cycle pregnancies surveillance related? Context: To assess the reportedly higher miscarriage rate during menotropin-induced cycle pregnancies as compared with natural cycle. Prospective cohort groups were selected, and pregnancies were identified 16 to 18 days after insemination and followed through to outcome. Three hundred twelve patients were studied: 251 women receiving human menopausal gonadotropin and 61 requiring donor insemination without medication. A significant difference between the spontaneous abortion rate of gonadotropin-treated women (28.5%) and women conceiving during natural cycles (11.7%) was demonstrated.
