Infertility

A diagnosis of infertility is made when a man and woman have unprotected intercourse for one year without conceiving or for six months if the woman is over 35. The cause of this lack of conception can be due a problem affecting either or both partners. Both men and women suffer from infertility equally.

Infertility is not the same as sterility, which is an inability to have children. While 15% of couples in the United States are infertile, only 1-2% are sterile. Up to 50% of couples seeking medical help for infertility go on to become pregnant.

  • Uterine abnormalities
  • Eating disorders

For men, the four most common causes of infertility are:

  • Low sperm count
  • Low sperm motility
