Laparoscopic Ovarian Drilling Reduces Testosterone and Luteinizing Hormone/Follicle-Stimulating Hormone Ratio and Improves Clinical Outcome in Women with Polycystic Ovary Syndrome.

Background: Laparoscopic ovarian drilling (LOD) is one of the common modes of treatment for women with polycystic ovary syndrome (PCOS) who are resistant to clomiphene citrate. The data related to the effect of LOD on sex hormones are limited.

Aim: The objective of the study was to investigate the effect of LOD on hormonal parameters and clinical outcomes in women with PCOS.

Settings and Design: This study was conducted in a tertiary care hospital.

Materials and Methods: Fifty PCOS patients who were admitted for LOD were enrolled in the study. Serum testosterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH) levels were estimated in all the patients before and after LOD.

Statistical Analysis: Paired t -test was used to assess the differences in hormonal parameters before and after LOD.

Results: LOD reduces testosterone ( P < 0.001), LH ( P < 0.001), and LH/FSH ratio ( P < 0.001), increases FSH ( P < 0.001) levels, and improves the rate of ovulation (38/50) and clinical pregnancy (21/50) in PCOS. When subgroup analysis was done, LOD significantly reduced testosterone and LH/FSH ratio in ovulatory and conceived groups. Furthermore, the menstrual cycle became regular, and hirsutism and acne were reduced after LOD in women with PCOS.

Conclusions: LOD reduces testosterone and LH/FSH ratio and improves clinical outcome in PCOS.
