Why do women tend to be more flexible by nature?

Question

I understand that male are generally stronger to survive centuries ago, but why do female tend to be more flexible?

In: Biology

Answer 1

Testosterone causes the tendons to thicken over prolonged exposure, this reduces mobility and flexibility its why male athletes have a shelf life when it comes to sports that require high motility.

TL;DR: Hormones, the male specfic androgen in this case makes tendons thicker and less stretchy, this being the opposite for the female specific androgen as it makes it easier for the female body to accommodate child birth.
