Actually PM doesn´t increase your testosterone. Besides of being a powerful phytoestrogen, PM is a soft anti androgen.
Regarding your other question the answers is yes: Progesterone sadly plays a part in keeping fat off your butt.

Good luck !

Whoa. I had no idea progesterone does this too. Can you point me to the source? I would like to learn more about this because my butts are already small as they are.

hi ! the source is in spanish ( http://www.chicanol.com/tag/nalgas/) But the same information you can find it in black hair media forum / body Types, ( search for lil_lisa)

I can't read spanish but lil_lisa seems to have tons of helpful information. Thanks for the reference Ceci!
