Abstract

Objective(s): Disrupted lipid metabolism has been associated with the development of polycystic ovary syndrome (PCOS) in women of reproductive age. Hormone-sensitive lipase (HSL) is an intracellular lipase that has a crucial role in normal lipid metabolism. This study aimed to assess the frequency of C-60G polymorphism of HSL in healthy women and PCOS women, and its correlation with infertility and recurrent spontaneous abortion (RSA) in PCOS patients. Study design: A total of 324 PCOS patients (including 199 infertile patients and 125 patients with a history of RSA and 144 healthy controls) were enrolled in this study. Biochemical parameters were measured, and the genotypes of C-60G polymorphism of the HSL gene were determined using PCR-restriction fragment length polymorphism (RFLP) techniques. Results: There was no significant difference in the genotype and allele frequencies of C-60G polymorphism between PCOS, PCOS-infertile woman, and non-PCOS subjects. However, a higher percentage of combined variants (CG + GG) and CG genotypes, as well as G allele was found in the PCOS-RSA group in comparison with non-PCOS women. The presence of the G allele conferred a 2.4-fold risk for RSA in women with PCOS (OR: 2.4, 95 % CI [1.22–4.70], P = 0.011). Furthermore, a significant correlation between CG or GG genotype of HSL and the level of free testosterone was observed. Conclusion: According to the obtained results, the C-60G polymorphism in the HSL promoter was associated with PCOS-related RSA, possibly through increasing the level of free testosterone. Therefore, the rs34845087 polymorphism may be a promising prognostic biomarker for RSA in women with PCOS. © 2023
