What causes infertility?
The three major causes of infertility account for over 80% of cases diagnosed. They include ovulation problems, sperm problems, and fallopian tube problems, while 15% of couples have unexplained infertility which is defined as infertility without a specific reason.
Reasons for infertility are found after extensive infertility tests in about 85% of couples, about 1/3 in men only, 1/3 in women only, and 1/3 in both men and women or unexplained. Most of these tests can be completed within 4-6 weeks. After infertility testing, about 85% of couples will have one or more reasons for their infertility. When no cause is found, the diagnosis is "unexplained infertility".
