Changing Attitudes Toward Male Fertility
About 10 percent of heterosexual couples in the U.S. are defined as infertile, based on the inability to conceive after 12 months of unprotected sexual intercourse. When women have trouble conceiving, they usually are the first to look for causes of infertility and to seek treatment.
Yet modern science has determined that 40 to 50 percent of all infertility cases are due in part or in whole to the male partner, which is known as male factor infertility. More and more, men are becoming more aware of the importance of their fertility and taking steps to make sure they can have a family.
