Infertility
What is Infertility?
Infertility is often defined as the "the inability of a couple to achieve conception ... after a year or more of regular, unprotected intercourse." This definition usually applies to couples where the woman is in her reproductive age.
What is the Incidence Worldwide?
The World Health Organization (WHO) approximates that 8-10% of couples worldwide experience problems with fertility. Infertility problems are not specific to a certain race or sex. Infertility is exclusively a male problem in approximately 10-30% of cases worldwide, and it is exclusively a female problem in approximately 30-40% of cases worldwide. Infertility can also be a result of combined problems between the male and female couple. Combined causes of infertility are estimated to occur in 15-30% of couples worldwide. Finally, even after careful investigation and evaluation, in some cases (5-10%) the reasons for infertility remain unexplained. When the cause for infertility cannot be deduced this is referred to as unexplained infertility.
