Throughout history, infertility has mainly been seen as a female problem, but the reality is far from that. When it comes to couples trying to have a baby, infertility is evenly distributed between the sexes: 30 percent due to male problems, 30 percent female, 10 percent male and female combined and 20 percent unexplained. Age is a factor for both.
When seeking answers from a physician for the cause of infertility, men and women can expect myriad tests, ranging from relatively noninvasive blood draws to minor outpatient procedures.
