Infertility is the inability to become pregnant after a year of unprotected intercourse, six months if the female is older than 35. It can result from fertility problems with either the male, female or both.
Infertility in women has different causes. These can include ovulation disorders, hormone imbalances, fallopian tube disorders and endometriosis. Reproductive Science Center of the San Francisco Bay Area can help.
For a man to be fertile, his sperm cells must be healthy and be transported to their destination - the egg. Most cases of male infertility are due to sperm abnormalities, yet other factors can play a role.
