Married men with and without children have significantly lower testosterone levels than unmarried ones and the more time a man spends with his wife
and children, the lower his testosterone level.
A man's testosterone levels drop significantly when he holds an infant. Testosterone begins to decline shortly after marriage, but surges upward when unions end in divorce. High levels of testosterone cause men to fight and mate. Lower levels of testosterone may keep men home to care for their wives and children.
