Over the past five decades, numerous studies have reported declining semen quality.

The average sperm count has dropped by half in men, from 99 million sperm per millilitre to 47 million per millilitre. This number is on the verge of hitting the World Health Organization's (WHO) measure of low-quality sperm, which is 40 million per millilitre.
