Are there real possibilities to become pregnant at 36 if you have "endometriosis" (endometrium disease, some cyist benign) and my partner is 60 and had a vasectomy reversal ( that was a success, after 17 years ) ?

Yes, its possible.

Only a doctor can give you specific information if you take fertility tests, but as long as you are ovulating and he's producing sperm, there is a chance!
