Study hypothesis
Laparoscopic ovarian diathermy (LOD) is currently widely used as an effective second line treatment for induction of ovulation in anovular infertile women with polycyctic ovarian syndrome (PCOS) after failure of a course of clomiphene citrate (CC). CC treatment is associated with significant drawbacks including a lower than expected pregnancy rate, high miscarriage rate (about 40%) and increased incidence of multiple pregnancies (10%). These well-documented drawbacks to CC create equipoise between CC and LOD. The aim of this study is to test the hypothesis that LOD used as a first line treatment in these cases will generate better pregnancy rates with fewer multiple pregnancies and higher live birth rate than treatment with clomiphene citrate.
