All over the internet news outlets and bloggers alike have been reporting on new study results that links fatherhood to a drop in testosterone in men. The new study answers just some of the questions from previous studies that simply determined men who were fathers had lower testosterone levels than their single counterparts.

One of the dispelled notions was that men with lower testosterone levels were more likely to become fathers with the opposite determination proving that men with higher testosterone levels were more likely to find a mate and become fathers.

The study led by Lee Gettler, Northwest University biological anthropologist, and his colleagues researched 624 men in the Philippines whose testosterone levels were measured over a five-year span.

The t-levels in men who remained single and without children remained stable but for those who became fathers the levels dropped dramatically - about in half - right after the birth of a child. The testosterone levels in the new fathers then rebounded but in varying amounts.
