Key Questions Answered
Data shows that since 1973, the global sperm count has dropped by 51 percent. Furthermore, a 2022 study analyzing over 223 studies found that average sperm concentration dropped by about 51.6% and total sperm count dropped by about 62.3% through 2018.
Research indicates that obesity, diabetes, metabolic syndrome, and stress are linked to poor semen quality and sperm DNA damage. Additionally, habits such as smoking, alcohol and tobacco use, sleeping fewer than six hours nightly, and exposure to heatwaves can negatively impact sperm concentration and count.
Sperm concentration refers to how many sperm are present in one milliliter of semen. In contrast, total sperm count refers to the entire number of sperm present in the full volume of semen released during a single ejaculation.
