ObGyn Intelligence — Evidence Matters

♂

Male Fertility

A male factor is present in about half of infertile couples — yet the workup still defaults to the woman. These tools screen, test, interpret, and optimize the male side, in the order a couple actually moves through it.

~50%

of infertile couples have a male-factor component (sole in ~20%, contributing in 30–40%)

24%

of OB/GYNs would routinely refer to urology before ordering a semen analysis

~40%

of men presenting with infertility have a varicocele — the most common correctable cause
