It may shock many men that after being a father, their testosterone level dips drastically, though it could be for a short while. It was being told by a team from Northwestern University after over 600 men from the Philippines were studied for five long years.

It's being known that to drive sex, men need to have high level of the hormone, and lack of it makes it more difficult to gain the desired power to make love.

Confirming the same, Lee Gettler, of Northwestern University, said: "The men who started with high testosterone were more likely to become fathers, but once they did, their testosterone went down substantially".

Moreover, it has been known that fatherhood brings lot of responsibilities both at the emotional and physical front, and thus, a significant change in man's biology is quite reflected in his day-to-day life.

Even regaining the level of energy become anomaly in itself, and with the study capturing attention of many fathers and young men, it seems that a thought process needs to be electrified to ensure that a balance is being strike between being a father and a man.

Moreover, it's being called for that a lot needs to be done to probe the theory surrounding men's testosterone levels.
