It is common knowledge that sexuality changes over time. But still, low sex drive, regardless of its prevalence, can be a cause of concern for men and their relationship. Identifying causes why men lose interest in sex may give you the insight to help get your sex life back on track.

Common Reasons Why Men Lose Interest in Sex

It is natural to lose interest in sex from time to time. However, an underlying health condition may cause prolonged periods of low sexual desire in men. Several factors can influence long periods of low sex drive. Here are a few potential health causes why men lose interest in sex:


The gradual decrease in sex drive (libido) in men is common with aging. The rate of decline may vary per individual. However, most men retain some amount of sexual interest up to their 60s and 70s. Decreased sex drive may be related to low testosterone levels. Testosterone levels in men naturally decrease with time because of factors such as a rise in comorbidities or existing illnesses and the aging population.

Low Testosterone

Aging is the primary factor of testosterone decline. The common symptoms include low sex drive, depression, decreased brain performance, lack of energy, and ED. However, men under 40 may also have low testosterone levels. The finding in a recent study shows a 20% testosterone level deficiency among young males aged 15-39 years old in the United States. The study concluded that total testosterone levels have been declining in young adult men in recent decades, specifically in 2001-2016, compared to the previous years covered in the data analysis. If you experience the symptoms of low testosterone, consult your doctor for possible treatment options. Testosterone Replacement Therapy (TRT) is one of the ways to treat low testosterone levels among men.

Medications Side Effect

Prescription medications may also cause low libido in men due to their side effects. For example, high cholesterol medications such as statins and fibrates interfere with the production of hormones like testosterone. Statins and fibrates may also cause erectile dysfunction (ED). Other medications that may decrease testosterone levels include:
  • Blood pressure medications
  • Antidepressants
  • Antipsychotics
  • Benzodiazepines
  • Corticosteroids
  • Hormones for prostate cancer treatment
