I don't want to derail the thread... but I was wondering: do people feel that doing a PhD is harder for a woman than a man?
I think it was harder for me as a woman, but that may have something to do with the institution where I was studying which was most definitely the wrong place for me to be at the time. They took a distinctly macho attitude to the whole thing: I was basically told - "You've got a pen, get to the British Library, and we will see you in 3 years". I had about 6 supervisions through the whole process, my supervisor vanished half way through to write a book about stalking someone (yes, really). I almost had a nervous breakdown trying to write all my research up without any guidance, and my supervisor didn't deign to read the final draft, but did tell me that he suspected I would fail. Despite the fact that I passed first time with no corrections, with glowing comments from both examiners, what I remember was his skepticism.
I was young (23 when I finished) and shy and when I was at staff meetings, I got comments like "Do students have frat parties now? I would LOVE to see shove at a frat party". (Yep, this was actually said, out loud, in front of the entire staff). I had formerly worked as a model, and shots of me in underwear campaigns were circulated around the department. I once found them pinned outside a classroom in which I was teaching, and had to walk in knowing all the undergraduates (only a few years younger than me at the time) had seen them. I felt so humiliated and demeaned by the whole thing, yet I took it because I thought that's what the world 'was like'. My male colleague explained to me that I was 'supposed' to be flattered by this. 
I experienced a lot of incredibly articulate and self-confident men who behaved as if they were born to hold the floor. If you wanted to disagree with them, you had to be prepared to battle through a host of belittling tactics all of which were designed to preserve their ego. I think this was partly class (everyone from my cohort was from a selective school except me) but also gender. I felt like I completely lacked what I most needed, which was a more senior woman to hold my hand and say 'You got here on merit, and you deserve your place. Now get out there, and have some confidence in your voice'.
To be honest, I'm now 37 and I'm only just recovering from the whole thing to feel that I do have a right to publish and to speak out. I've lost over 10 years in which I've felt shit about myself. When I left I worked in crap, menial jobs for a couple of years because I didn't feel I had a right to do anything else. I gradually fell into being quite an interventionist editor, essentially rewriting other people's academic papers for them so that they could take the credit for my voice. It was only after years of doing this that I started to realise that maybe, just maybe the fact that I could take a very senior person's work and rehash it completely to make it a lot better meant that I could probably write for myself. I'm still struggling with the whole 'having a voice' thing, but I have now started to publish and I have no intention of shutting up!
