We told you in our earlier reports on this topic that infertility refers to the biological inability of an individual to contribute to conception, or to a female who cannot carry a pregnancy to full term. The causes of male infertility may include abnormal sperm production or function due to various problems such as undescended testicles, genetic defects, health problems such as diabetes, or infections such as mumps.

The doctors tell us that enlarged veins in the testes (varicocele) can also increase blood flow and heat, affecting the number and shape of sperms. Problems with the delivery of sperm due to sexual problems, such as premature ejaculation; semen entering the bladder instead of emerging through the penis during orgasm (retrograde ejaculation); certain genetic diseases, such as cystic fibrosis; structural problems, such as blockage of the part of the testicle that contains sperm (epididymis); or damage or injury to the reproductive organs may also cause infertility in men.
But Ugandan doctors add that overexposure to pesticides and other chemicals, radiation, or to some medications, such as anabolic steroids, and marijuana cause infertility. The frequent exposure to heat like in saunas can elevate core body temperature, impairing sperm production and cause infertility. Body damage related to cancer and its treatment procedure such as radiation or chemotherapy causes infertility. Treatment for cancer impairs sperm production.
