Yes, binge drinking can negatively affect male fertility.
Several studies have shown that heavy or binge drinking can lead to reduced sperm quality and production.
A Danish study found that men who binge drank (5 or more drinks in a few hours) had lower sperm counts and altered reproductive hormone levels compared to non-binge drinkers.
Heavy drinking, defined as 15 or more drinks per week, can lower testosterone levels and reduce sperm production by impacting hormones like follicle-stimulating hormone and luteinizing hormone.
Alcohol abuse and acute intoxication can also cause sexual dysfunction like erectile dysfunction or premature ejaculation, which can hinder conception.
