Male fertility drops 62% worldwide and accelerates

The collapse in male fertility rates around the world is accelerating, according to the journal Human Reproduction Update.

Sperm counts have dropped 62% in less than 50 years – a decades-long trend that is accelerating.

Low sperm counts can contribute to adverse health effects in men, including “testicular cancer, hormonal disruptions and genital birth defects, as well as declining reproductive health in women.”

Hagai Levine, lead author of the study, called the problem a “crisis”, warning that the steep decline could reach an irreversible point.

“We have a serious problem on our hands which, if not alleviated, could threaten the survival of humanity,” he added.

Since 2000, there has been a 2.64% annual decline in sperm count per milliliter of semen, more than double the number seen since 1978.

Although this study does not address potential causes, other studies have linked low sperm count to obesity, sedentary lifestyles, smoking, and exposure to certain chemicals and pesticides.

Many of these chemicals are found in widely used everyday items, ranging from personal care products to food packaging, according to study co-author Shanna Swan.

These endocrine disrupting chemicals are commonly found as liners in water bottles and take-out containers. Bisphenol A (BPA) is another chemical added to food packaging linked to fertility issues.

While the world’s population recently reached eight billion, birth rates around the world are steadily declining.
