Intracytoplasmic sperm injection outcome of women over 39: an analysis of 668 cycles.

PURPOSE: To evaluate intracytoplasmic sperm injection (ICSI) outcome of women over age 39 and to determine when to discourage such couples to undergo IVF using their own oocytes. METHODS: Four hundred ninety-five consecutive women (n=668 cycles) over age 39 were evaluated by year-by-year age increments to discriminate the independent prognostic factors for the achievement of pregnancy. RESULTS: Although the ovarian hyperstimulation performance (COH) and embryological data were not too diverse, the clinical pregnancy rates per embryo transfer decreased from 26 to 13% from age 40 to 44. According to logistic regression, the female age seems to be the only variable in order to predict an ongoing pregnancy. The miscarriage rate increased with advancing female age. It was 33% at age 40 but increased to 100% by age 45. CONCLUSIONS: The performance of COH and embryological data is not discouraging among women over 39 years in ICSI cycles. However, increased miscarriages as well as decreased implantation rate are mainly responsible for the poor performance of patients with advanced female age. Irrespective of the ovarian reserve testing, ICSI may be refused at age 45 and thereafter.[1]
