The effect of weight reduction on the sexual function and reproductive health of obese men

Introduction
Obesity is a disease that significantly increases the risk of death in all ages. It is a risk factor for the development of many diseases that directly affect male reproductive health. Metabolic complications resulting from excess body weight affect testosterone levels and gonadal function in men. Morbid obesity causes hypogonadism in men and an increase in androgen secretion in women. The consequences of overweight and obesity in men are a decrease in testosterone and sex hormone-binding globulin (SHBG), an increase in oestradiol, sexual dysfunction, and reproductive health dysfunction. Surgical weight reduction improves the sexual function and reproductive health of men.

Material and methods
To investigate the effect of weight loss in obesity on male sexual function and reproductive health.

Material and methods
Research material was collected by searching through databases with scientific articles on obesity, bariatric surgery, the effects of bariatric surgery on sex hormones, sexual function, and fertility in men. The Pubmed and Web of Science research databases were used. Scientific articles, systematic reviews, and meta-analyses were taken into account. The analysis of the included articles covered items from 2003 to 2021. One of the publications dates back to 1996.

Conclusions
Surgical weight reduction improves the profile of male sex hormones and sexual function. The problem of the associations between male sperm quality and surgical weight reduction requires further research.
