Abstract
Objective To assess the effectiveness of a second laparoscopic ovarian diathermy (LOD) in women with polycystic ovary syndrome (PCOS). Design Retrospective study. Setting Tertiary infertility clinic. Patient(s) Twenty anovulatory infertile women with PCOS who underwent LOD 1–6 years previously. Twelve subjects had previously responded positively to the first LOD, but the anovulatory status recurred (Group I), whereas eight subjects had not responded at all (Group II). Intervention(s) Laparoscopic ovarian diathermy. Main outcome measure(s) Rates of ovulation, pregnancy and resumption of menstrual regularity, and biochemical changes. Result(s) An overall ovulation rate of 12 out of 20 women (60%) and a pregnancy rate of 10 out of 19 (53%) were achieved after the second LOD. In women (n = 12) who previously responded positively to the first LOD (LOD-sensitive), the ovulation and pregnancy rates were 10 out of 12 (83%) and 8 out of 12 women (67%), respectively, which were significantly ( P<.05) higher than 2 out of 8 (25%) and 2 out of 7 (29%) of the previous nonresponders (LOD-resistant). Statistically significant hormonal changes including reduction of luteinizing hormone (LH), testosterone (T), and free androgen index (FAI) after the repeat LOD were only observed in the LOD-sensitive group. Conclusion(s) Repeat LOD is highly effective in women who previously responded to the first procedure.
