I just caught up on this thread, rather late I know. Way back, on about Page 4, someone asked about female helicopter pilots on the North Sea, and suggested there wouldn't be many. Well, when I visited a (female) pilot friend in Aberdeen, two years ago, the company she worked for had six female pilots and 150 men. That's 4%, very similar to many of the airlines.
Other than passing on that bit of info, I have nothing to say. Despite the fact that threads like this turn up on PPRuNe with monotonous regularity, I still find it unbelievable that there are people who think gender is of any relevance at all to flying.
But what do I know? I'm just a helicopter pilot....who thought my flying ability or lack of it depended on my hands, feet, eyes, coordination, brain, and training; not my hormones. Seems some people disagree.
