It's not a problem, it's just incomplete. From what I've seen, most studies (especially with animals) start out with only male participants, to eliminate the effect of menstruation and the related hormones, which we've seen can be very potent.

This makes it easier on the researchers trying to conduct a preliminary study. The limitations of the study just mean we can't necessarily generalize the results to both men and women, people of different weights, (nor, I suspect, people of various races,) or even, given the sample size, all men of normal weight.

But first we see if we can detect an effect in "normal weight" males, and then we have doubts about its applicability in other populations we test those populations. This of course isn't the most thorough way of experimentation, but it's the biggest bang for your buck when your resources and/or available subject pool are limited.

Interesting, never considered this.
