We already know that exercise offers multiple benefits, including improved reproductive health and better fertility potential. Even physical activity during work is good for your health. For example, a new study has found physically demanding work associated with significant improvement in men's reproductive potential. It suggested that men who regularly lift heavy objects at work have higher sperm counts, which means higher fertility potential. The study by researchers from Brigham and Women's Hospital was published in Human Reproduction.

Factors that can affect male fertility

Infertility rates are growing worldwide, and about 40 per cent of the cases are attributed to male factors. Male infertility is generally linked to sperm count, semen quality and sexual function. Particularly, sperm count and semen quality are considered the major drivers of growing infertility rates among men.

Additionally, male infertility have been linked to common chronic diseases such as cardiovascular disease and autoimmune disease, highlighted first author Lidia M nguez-Alarc n, a reproductive epidemiologist in Brigham's Channing Division of Network Medicine.
