Men’s infertility arises from problems related to sperm production, functionality, or transportation, which may be attributed to genetic disorders, infections (such as mumps or sexually transmitted infections), hormonal irregularities, varicocele (enlarged veins in the scrotum), issues with ejaculation, cancer therapies, and environmental influences including toxins or high temperatures.
Lifestyle factors such as excessive consumption of alcohol, tobacco, or marijuana, along with exposure to harmful chemicals and inadequate nutrition, can further exacerbate infertility.
