I'm not surprised he doesn't know about them. Why would he? It's not something that would be covered by CPD .While they are fine some people, they aren't suitable for everyone. I certainly found it very uncomfortable.
Agree with this. Whether he is 'elderly' or not, (and the OP doesn't seem to want to say how old,) it's perfectly OK for him to have not heard of menstrual cups. I never heard of them til about 4 or 5 years ago, and would certainly not ever 'wear' one.
Me and DH, and our adult children, AND a number of people we know, have been (with various ailments,) to many male and female GPs of various ages, and they sometimes GOOGLE the symptoms to try and see what it could be.
In addition, they sometimes pore through a book to see what meds they should be giving. So - as a few posters have said - many of them have limited medical knowledge.
Some are very good, but there are some GPs that are so clueless that I swear I know more than them about most stuff. The only reason I go is because I can't write my own prescriptions!
Going back to the OP's point... Why anyone thinks it's weird for an 'elderly' male doctor to have never heard of menstrual cups, just baffles me. And he is entitled to his opinion that it doesn't seem like a good idea to have it stuck up there for days on end. Many would agree.
Have to say also, I have NEVER seen menstrual cups advertised, nor have I seen them for sale anywhere. Maybe there are for sale in pharmacies/supermarkets, but I have never seen them.
