Hormone ng mga kalalakihan bumababa matapos maging ama

Ayon sa article na mababasa sa New York Times at sa The Guardian, may malaking pagbaba sa level testosterone sa ating mga kalalakihan kapag tayo ay Tatay na, batay sa pag-aaral ng mga eksperto at pagsusuri sa dugo (blood tests) ng 624 mga lalaki sa Pilipinas.

Ayon pa sa article:

Men who devoted at least three hours a day to childcare had even less testosterone, suggesting that looking after dependent children helped suppress the hormone. Testosterone is responsible for the male body shape, the distribution (and loss) of hair and a man's sex drive.
Previous studies have shown that fathers tend to have lower testosterone, but it was unclear whether men with reduced levels were more likely to have children, or whether parenthood pushed testosterone down.
