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

What causes infertility in women?

Problems with ovulation account for most cases of infertility in women. Without ovulation, there are no eggs to be fertilized. Some signs that a woman is not ovulating normally include irregular or absent menstrual periods.

Less common causes of fertility problems in women include:

• blocked fallopian tubes due to pelvic inflammatory disease, endometriosis, or surgery for an ectopic pregnancy
• physical problems with the uterus
• uterine fibroids
