I doubt that more than a few women are actually ‘impaired’ by a spike in hormones. Our hormones naturally fluctuate all the time just from normal physiological processes. Let’s just say that approximately .01% of people experience a serious adverse side effect from a medication. 99% of the time in such cases, a pilot would say, “I don’t feel right, I shouldn’t fly today” and there would be no safety issue. So in order to prevent something bad with a .0001% chance, the FAA automatically grounds the pilot. It’s a stupid knee-jerk reaction that helps no one. The FAA ought to change from a stance of “we won’t issue a medical if there’s any chance something is wrong with you” to “we will issue a medical UNLESS we have positive evidence that something is wrong with you.” That alone would solve most of the problems that pilots have with the FAA.
