Nearly 1 in 10 men will experience infertility. Almost 40% of infertility cases in couples are traced back to a medical condition or other contributing factors from a male partner. Traces of infertility in men can range from issues with sperm production to interference with sperm delivery. Once you have come to the conclusion that you are having issues conceiving, the fertility experts at SIRM St. Louis believe it’s important that both partners are tested.

Probable Causes

Male infertility can be caused by physiological and lifestyle factors. Some physiological factors we commonly see at our
Missouri fertility clinic include:

  • Genetic disorders
  • Hormonal imbalances
  • Infection (acute and/or chronic infections of the prostate or testicle)
  • Anatomic issues (blockages, varicocele, tumors)
  • Previous surgery or vasectomy
  • Direct injury (testicular or pelvic trauma, heat, irradiation, etc.)
  • Indirect injury (radiation therapy, chemotherapy, etc.)
  • Obesity
  • Diabetes
  • Undescended testicles with late repair

Additionally, our St. Louis fertility doctors note that common lifestyle factors may contribute to infertility in men. These include:


Studies suggest that smokers may have lower sperm count than those who don’t smoke. Secondhand smoke may also affect male fertility.

Excessive Heat Exposure

Potential increased scrotum temperature due to frequent use of saunas or hot tubs may temporarily lower a man’s sperm count. Additionally, anything that even slightly raises scrotum temperature – sitting for long periods, wearing light clothing, or working on a laptop computer – can have a similar effect.

Excessive Alcohol

Alcohol has been shown to lower testosterone levels, lower sperm count, and potentially cause erectile dysfunction. Men with liver disease caused by excessive drinking may also have trouble conceiving.


Emotional stress disrupts the body’s hormone production, which can affect the production of healthy sperm. Men who feel stressed are more likely to have lower concentrations of sperm in their ejaculate, and the sperm they have are more likely to be misshapen or have impaired mobility. These deficits could be associated with fertility problems.
