How are some men able to lactate when it only occurs during pregnancy?

355 views

If I’m not mistaken, lactation only occurs during pregnancy or after birth when the body has the correct hormones. I have never heard of non-pregnant women randomly lactating, yet there are men who do.
I understand men can develop the correct “equipment,” but why would they be experiencing the hormones needed to cause milk production when they aren’t pregnant? Women are capable of pregnancy but their bodies don’t make milk randomly.

It only happens when the hormone prolactin is present in the body. Females make this hormone when they are pregnant and nursing. In a male, you’d have to use a drug to generate this hormone.
