What is infertility?
Infertility is the inability to get pregnant after trying for at least 1 year without using birth control. About 16% of couples are infertile.
How often are male factors involved?
About 30% of cases of infertility are caused by male factors alone. A combination of male and female factors causes about 20% of cases of infertility.
When should I contact a healthcare provider?
Usually, a couple should wait to contact a healthcare provider until after they’ve tried to get pregnant for a year. However, it’s okay to contact a healthcare provider sooner, especially if the woman’s age may be a factor.
CAUSES & RISK FACTORS
What causes male infertility?
The most common cause of male infertility is a varicocele (say: “var-ih-koh-seal”). A varicocele is made up of enlarged veins in the scrotum (the skin “sack” that hangs beneath the penis) on 1 or both sides. The veins make the inside of the scrotum warmer and can reduce sperm production by the testicle on the same side.
Other causes of male infertility include:
- A blockage in a man’s reproductive system
- Certain medicines
- Low sperm count
- Sperm that are abnormally shaped or that don’t move correctly
- Undescended testicles
- An underlying medical problem
Other factors that may affect fertility include tobacco smoking, excessive alcohol consumption and abuse of other illegal drugs, emotional stress, obesity and age (fertility gradually decreases in men who are older than 35). Sometimes the cause of male infertility cannot be identified. In these cases, there may be an underlying genetic problem.
DIAGNOSIS & TESTS
Should men be checked for infertility?
Yes. It’s important to identify and treat any correctable problems. In some men, a healthcare provider’s exam may find an underlying medical problem that is causing the infertility.
How is infertility evaluated?
Your healthcare provider will talk to you about your medical history, examine you and test your semen. Your healthcare provider may want to test your semen more than once. A semen analysis can tell your healthcare provider about your sperm count and sperm quality. These are important parts of fertility. Your healthcare provider may recommend other tests depending on the results of this first evaluation.
Is male infertility treatable?
More than one-half of cases of male infertility can be corrected. Treatment may help a couple get pregnant through normal sexual intercourse. Even if you can’t get pregnant in this way, you may not need expensive or invasive treatments to get pregnant. If the man needs surgery to correct the problem that is causing his infertility, it can often be done as an outpatient procedure. This means he doesn’t have to stay in the hospital overnight.
