Wikipedia tells me that men have 7 to 8 time higher levels of testosterone than women, on average.
Since the hormone is linked with performance in certain athletic events, my hypothesis, which I presented to a disagreeing friend, is that female top athletes in certain fields will have levels above the average male.
I found Why do endocrine profiles in elite athletes differ between sports? (Clinical Diabetes and Endocrinology 2018) which in Figure 10 presented testosterone levels for men and women in a number of olympic athletes:
As you can see in the plot it seems that even in the cohort of olympians there is an overlap, even if small, between men and women. Am I misinterpreting these result? I noticed that the units (nmol/L) are different from those used on Wikipedia (ng/dL), is this somehow important?
Are there information about the distribution of testosterone levels among the general population to help answer the question of the share of women exceeding the average male level?
Am I interpreting the above results correct, are there indeed female olympians with higher testosterone levels than male olympians?
