Pregnancy rates after laparoscopy for infertility

To obtain prognostic data on the likelihood of pregnancy in infertile women with no observable abnormalities at diagnostic laparoscopy, the occurrence of pregnancy was studied in a series of 229 patients. The cumulative conception rate during a follow-up period of at most 5 yr was 50%. The probability of pregnancy proved to decline with age and duration of infertility. The cumulative conception rate during the first year after laparoscopy was approx. 30%, and there was no significant difference between the patients that were treated with respect to other sub-optimal fertility factors (subfertile group) and the patients in whom no rational treatment could be instituted (unexplained infertility group). Implications of these findings with respect to the treatment of long-term infertility are discussed. Knowledge of pregnancy rates after infertility laparoscopy seems important for the evaluation of results of therapy in unexplained infertility.
