Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Obesity has been found to be a risk factor for female infertility. Studies have indicated that obese men often have poor semen quality and require increased time to make partner pregnant. To date, no studies have investigated the effect of weight reduction on male fertility. The purpose of this study is to investigate the effect of weight reduction in overweight and obese men on their reproductive function.
