Well, a gynAecologist is a doctor who specializes is the female reproductive system. Note, not every women goes to a gyn b/c their primary care doctor is all purpose enough to hand basic female needs. Pap smear, BC, etc. So no, not every one, or even every woman has to go to a gyn
Everyone? Haha no only females. And another item to the list of reasons I live being a man! :-) When I was in the Air Force, one of our favorite tricks to play on the new guy was to send him to the base clinic for a pap smear! HAHAHA!
All WOMEN should visit the OB/GYN regularly as soon as they become sexually active or by age 21, whichever comes first. MEN, on the otherhand, should begin regular prostate exams with their regular doctor by age 40.
