Serum progranulin levels are elevated in infertile women with obesity.

INTRODUCTION

The aim of the present study was to investigate the changes in serum progranulin and sex hormone levels in infertile women with obesity.

MATERIAL AND METHODS

A total of 171 infertile women who had fertility desire were included in this cross-sectional study. The initial assessment included measurements of weight, height, waist circumference, and hip circumference to calculate body mass index (BMI) and waist/hip ratio. All participants were categorised into two groups in accordance with BMI as a control group ( < 30 kg/m², n = 135) and a study group (≥ 30 kg/m², n = 36). After anthropometric measurements, venous blood samples were taken for analyses of oestradiol and follicle stimulating hormone (FSH), luteinising hormone, total testosterone (TT), 17-hydroxyprogesterone, dehydroepiandrosterone sulphate, anti-Müllerian hormone, and progranulin.

RESULTS

The present study demonstrated that the overweight women had higher FSH levels (p < 0.01). Elevated TT levels were detected in obese women (p < 0.05). Progranulin concentrations were higher in the study group than in the control group (p < 0.05). Regression analysis demonstrated that there was a relationship between the serum progranulin concentrations and BMI (p < 0.05).

CONCLUSIONS

Our findings support that the elevated progranulin levels are associated with obesity in infertile women. Therefore, infertile and obese patients may benefit if their serum progranulin levels decrease. Further studies are needed to elucidate this issue.
