The Impact of Obesity on Some Reproductive Hormones in Infertile Men

Abstract

Background: Obesity, defined by the World Health Organization (WHO) as “abnormal or excessive fat accumulation that may impair health .The effects of obesity on male reproduction have been less well studied than those on female reproduction, but there is a growing body of evidence suggesting that obesity has an adverse effect on male reproduction However, a little is known about the effect of obesity on male reproductive system and infertility. Infertility is defined as inability to achieve conception within one year. It has not yet been clearly established how excess adiposity relates to the biological changes that underlie male infertility, although there are several theories worth exploring. The endocrine abnormalities associated with obesity in women are well known with an increase in androgen metabolism and changing in reproductive hormones in over weight and obese men. Objective: The study aim at assessing the role of obesity in infertile males through measurement of BMI, some of sex hormones. Methods: This study was carried out in Tikrit Teaching Hospital, on the adult male population aged 17-45 years, from September 2013 to April 2014. The recruited cases divided into 90 infertile obese male and 30 normal weights infertile as pathological control group and 30 normal weight fertile men as normal control group.The serum samples willed collect of the patients and measure the concentrations of the sex hormones (FSH, LH, INHB) by using ELISA technique. Body Mass Index Calculation Height (m) and weight (kg). Results: There was no significant correlation between BMI (30.1±93.45, 21.40±5.24,23.24±1.42)kg/m2 in patients group, pathological control group and control group and serum LH level (22.35±12.79, 19.31±9.94, 13.90±8.33) ml U/ml in all three group respectively. There was a significant negative correlation (P< 0.03) between BMI (23.24±1.42)kg/m2 and serum FSH level (7.10±3.77) ml U/ml, in control group. While there was no significant correlation between BMI (30.19±3.45,21.40 ±5.24) kg/m2 and serum FSH level (13.59±15.72, 11.58±14.06) ml U/ml in both patients' group and pathological control group respectively.There was no significant correlation between BMI (30.19±3.45, 21.40±5.24,23.2±1.42) kg/m2and serum INHB level in the patients group, pathological control group and control group (88.8±57.96, 108.51±78.39, 141.65±63.95) pg/ml respectively. Conclusions: The BMI did not correlated with some reproductive hormones (LH, FSH,INHB) in obese infertile males, but there was a significant correlation between the FSH and BMI in control group. In infertile obese group found the highest level of LH, FSH, and the lowest level of INHB comparing with other group in this study.
