Can obesity cause infertility in men?

By Victoria Moliner.
Last Update: 08/14/2018

Yes, it has been scientifically proven that those men with a body mass index higher than 30 have a worse seminal quality and, therefore, present greater difficulties to achieve a natural pregnancy.

In fact, men with excess weight tend to have low levels of androgens, such as testosterone, the hormone responsible for regulating the formation of sperm in the testicles. As a consequence of this decrease in male sex hormones, spermatogenesis is affected and oligozoospermia may appear.
