How Common is Male Infertility?

Male infertility is more common than you think. A diagnosis of infertility is typically made if a couple has been trying to conceive for one year (12 months or more) by having frequent and unprotected sex. If a couple is over the age of 30, a diagnosis of infertility may be made sooner, after six months of trying.

For couples that have trouble conceiving, many times it’s assumed that the woman is the cause of infertility. The truth is that for couples diagnosed with infertility, in about one-third of cases it’s the male alone who is the source of the problem.

What can cause infertility in men?

There are many causes of infertility in men, but usually the problem is with the production of sperm, or the inability to deliver sperm into a woman’s reproductive system.


Some medicines can reduce sperm production and sperm counts: These can range from chemotherapy drugs used for cancer treatments, seizure medications, antifungals, and testosterone treatments.

Transport problems

Sperm is made in the testicles, then needs to travel so it can mix with semen and become part of a male’s ejaculation fluid. But blockages within the testicles can prevent sperm from moving within the testicles to and through tubes that transportit and allow it to leave the body.


Sometimes an infection can cause a decrease in sperm counts, or cause inflammation within a man’s reproductive system. Inflammation may lead to blockages that prevent sperm from transporting properly.

Some of the other causes of infertility in men include:

Lifestyle choices can also contribute to male infertility

Obesity can alter sperm quality and hormone levels in males, which can make a man less fertile. There are a number of habits that can lower sperm counts, including:

Environmental toxins can cause harm, too. Exposure to pesticides, industrial chemicals, heavy metals (lead for example) and radiation and X-rays, can all contribute to the development of male infertility.
