The main symptom of infertility is not getting pregnant. There may be no other obvious symptoms. Sometimes, women with infertility may have irregular or absent menstrual periods. In some cases, men with infertility may have some signs of hormonal problems, such as changes in hair growth or sexual function.

Most couples will eventually conceive, with or without treatment.

When to see a doctor

You probably don’t need to see your health care provider about infertility unless you have been trying regularly to get pregnant for at least one year. Women should talk with a care provider earlier, however, if they:

• Are age 35 or older and have been trying to conceive for six months or longer
• Are over age 40
• Have irregular or absent periods
• Have very painful periods
• Have known fertility problems
• Have been diagnosed with endometriosis or pelvic inflammatory disease
• Have had multiple miscarriages
• Have undergone treatment for cancer

Men should talk to a health care provider if they have:

• A low sperm count or other problems with sperm
• A history of testicular, prostate or sexual problems
• Undergone treatment for cancer
• Small testicles or swelling in the scrotum
• Others in your family with infertility problems
