It surely can. My hormones were all over the place after stopping bcp and they never evened out up until now.

I believe it's called rebound effect. I used to be on bcp containing cyproteroneacetat which is a very potent anti-androgen. After quitting it my testo levels skyrocketed. They are better now but some changes that your body goes through under the influence are irreversible. Luckily they were not as harsh as they might have been.
