There was confusion over which bits of the body went to which butthole and gendered peepee doctors. I thought it was weird that the butthole doctor did the prostate because women also have buttholes and no prostate. I also thought it weird that a gynecologist did the entire reproductive system for women but the men's reproductive system was split between two doctors, one of which was a general urinary tract doctor for men and women (Urologist).
He clarified that a Urologist is strictly a male reproductive and urinary tract doctor (including prostate), a Gynecologist was the female reproductive and urinary tract doctor, and Proctologists no longer exist and are instead called Colorectal Surgeons that you'd not go to for a prostate exam unless referred due to serious concerns. So the confusion was mostly that Urologists aren't urinary tract doctors but instead male reproductive doctors, and Proctologist is an obsolete term.
