Part of it IS chemical; Estrogen and estrogen mimicking chemicals are found in the most common plastics, soy (unless it is the fermented and non-gmo soy), receipts, even because how many birth control pills women take, which works its way into the water supply.

Then there's the social factors, men are removed from the family as much as possible. Poor get perks for kicking the man out of the house and choosing welfare... so, there's a generation of men who were raised with missing or absent fathers and overbearing mothers. They never learned how to be men.

I wish it were as simple as just telling someone to "man up"... it is much bigger of an issue.
