The reproductive performance of 110 patients who had had gestational trophoblastic disease was reviewed. There were 160 pregnancies and their outcomes were similar to that of the general population. The subfertility rate was also comparable to the general population. The high rate of failure of contraception resulting in a high rate of conception during the first year of follow-up warrants special attention. Reasons for the high failure rate and ways of prevention are discussed. Reasons for the deliberate delay in attempts to conceive in patients after the full year of postmolar human chorionic gonadotropin (hCG) surveillance were explored.
