Comparison of Serum Levels of AMH and FSH Before and After Unilateral and Bilateral Laparoscopic Ovarian Drilling in PCOS Women Referred to YAS Infertility Clinic

Laparoscopic ovarian drilling (LOD) is a method for ovulation induction in polycystic ovary syndrome (PCOS) patients. The aim of this study was to evaluate the serum levels of anti-Mullerian hormone (AMH) and follicle-stimulating hormone (FSH) before and after LOD in one or two ovaries in women with PCOS.

This study was a prospective cohort study. The study population included infertile women with PCOS resistant to clomiphene referred to the Infertility Clinic of Yas Hospital. They were candidates for LOD in 2016–2017. The serum levels of AMH and FSH were measured before and after three months in two groups of unilateral and bilateral LOD. Data were analyzed using Stata software.

A total of 35 female patients were enrolled in the study, 18 (51.4%) in bilateral and 17 (46%) in unilateral LOD groups; the average age of patients was 27 ± 3.4 years old. AMH levels significantly (P<0.001) decreased in both unilateral and bilateral groups after LOD. FSH levels significantly (P<0.001) increased in both groups after LOD, but this increase was higher in the unilateral group than in the bilateral group, and this difference was statistically significant (P<0.001).

 It seems women with clomiphene-resistant PCOS when underwent unilateral or bilateral ovarian drilling experienced a significant decrease in AMH and a significant increase in FSH, indicating a decrease in their ovarian reserve.
