NOTHING. OMFG, absolutely NOTHING. I hated every single minute of what testosterone did to me, and I never want that poisonous crap back in my body.

The only thing I come even remotely close to missing is the upper body strength. (I swear, a 20-lb box of cat litter feels as heavy to me now as a 60-lb box of computer paper used to.) But then every time I come close to missing it, I look in the mirror and see how feminine in appearance my arms and shoulders are becoming, and then I quickly stop missing it because it's not worth putting up with that hideous bulky look just to have it.

If you want a list of things that I don't miss whatsoever, though, and things that I love WAY better on estrogen, I could write a freaking essay on the topic.
