HIstorically, strength of the hand was one of hte major muscular differnces between men and woman. It's interesting the differnece is decreasing, despite men still being able to create more muscle. Female athletes with too much testosterone are typically not allowed to compete or must be medically monitored precisely becaue testosterone is strength building.

.......The present findings show that the differences in hand-grip strength of men and women are larger than previously reported. An appreciable difference still remains when using lean body mass as reference. The results of female national elite athletes even indicate that the strength level attainable by extremely high training will rarely surpass the 50th percentile of untrained or not specifically trained men.

It is not publicly known how many hyperandrogenic women are competing in Rio. But a study published in 2014 by Dolle and other medical experts calculated that seven out of 1,000 elite female athletes may be hyperandrogenic, 140 times higher than expected among the general population. Hyperandrogenism is a medical condition that causes a person to produce high levels of hormones and can be caused by differences in sexual development.
