I would like to know if the reverse effect can be produced on women. Can women produce more testosterone in situations that would generally be considered more masculine? There seemed to be a very significant finding for men who just had newborns, perhaps it is triggered more by a major life event rather than specifically becoming a parent. For instance, does getting married reduce testosterone? Does losing a love one reduce it? Does moving to a new home? Makes for an interesting article and find(?) but I don't think it can be significant until it can be concluded that parenting specifically reduces that hormone.
