There are certainly female uros out there, they're just not as visible as their male counterparts.
Sometimes they do speak up as to why they chose urology as their specialty:https://www.bing.com/videos/search?q=female+urologist+exam+youtube&view=detail&mid=9e510464a0b7237c9b299e510464a0b7237c9b29&form=vire
And here's a good write-up giving some statistics on females in urology. For example, it notes that about
25 % of med students in urology right now are women, so that the number of female urologists in the near future is likely to grow. It also stresses that patient comfort level is probably the biggest single factor in accepting lady uros:https://www.cookmedical.com/urology/from-my-desk-women-in-urology/
But there's also something else going on here, regarding this apparent gender imbalance. Namely, that while we have traditionally thought of doctors in urology as men, don't we also almost always think of urology nurses
Now that I think about
it, In all the years I have had uro appointments, I don't ever recall seeing a male urological nurse. They were always women, and usually young women at that.
Lady urologists, and male urological nurses are probably out there, they just aren't all that common. Maybe that will change.
The imbalance may also be at least partially caused by a kind of vicious cycle due to patient expectation. For example, in another medical area, have any of you ever had your teeth cleaned by a male
dental technician? I never have. Always women, and usually young women. So the public expects the dental tech to be female, probably young, the dentist's office honors that expectation, the techs continue to be female, the public continues to be satisfied, and the cycle continues.
No harm is done if such a pattern of gender expectation exists in various medical specialties, but, as noted, maybe gender expectations will be changing in the future.
(BTW, I personally am entirely unconcerned with this issue. If I'm in a doctor's office, in an exam room, I'm there because of an issue that's bothering me, my mind is on that, and not whether the medical person in front of me is a he or a she).
