Infertility in Men

Infertility is not always a woman's problem. In only about one-third of cases is infertility due to the woman (female factors). In another one third of cases, infertility is due to the man (male factors). The remaining cases are caused by a mixture of male and female factors or by unknown factors.

What causes infertility in men?

Infertility in men is most often caused by :

• problems making sperm, producing too few sperm or none at all
• problems with the sperm's ability to reach the egg and fertilize it (abnormal sperm shape or structure prevent it from moving correctly)

Sometimes a man is born with the problems that affect his sperm. Other times problems start later in life due to illness or injury. For example, cystic fibrosis often causes infertility in men.

What increases a man's risk of infertility?

The number and quality of a man's sperm can be affected by his overall health and lifestyle. Some things that may reduce sperm number and/or quality include : alcohol, drugs, environmental toxins, including pesticides and lead, smoking, cigarettes, health problems, medicines, radiation treatment and chemotherapy for , cancer, age.

How will doctors find out if a man have fertility problems?

Sometimes doctors can find the cause of a couple's infertility by doing a complete fertility evaluation. This process usually begins with physical exams and health and sexual histories. If there are no obvious problems, like poorly timed intercourse or absence of ovulation, tests will be needed.

Finding the cause of infertility is often a long, complex and emotional process. It can take months for you and your doctor to complete all the needed exams and tests. So don't be alarmed if the problem is not found right away.

For a man, doctors usually begin by testing his semen. They look at the number, shape, and movement of the sperm. Sometimes doctors also suggest testing the level of a man's hormones.

How do doctors treat infertility?

Infertility can be treated with medicine, surgery, artificial insemination or assisted reproductive technology. Many times these treatments are combined. About two-thirds of couples who are treated for infertility are able to have a baby. In most cases infertility is treated with drugs or surgery.

Doctors recommend specific treatments for infertility based on : test results, how long the couple has been trying to get pregnant, the age of both the man and woman, the overall health of the partners, preference of the partners .

Doctors often treat infertility in men in the following ways :

• Sexual problems: If the man is impotent or has problems with premature ejaculation, doctors can help him address these issues. Behavioral therapy and/or medicines can be used in these cases.
• Too few sperm: If the man produces too few sperm, sometimes surgery can correct this problem. In other cases, doctors can surgically remove sperm from the male reproductive tract. Antibiotics can also be used to clear up infections affecting sperm count.
