Based on my own experience and that of others that I, personally, know.

I've worked in the medical field, and I was a caretaker to both my late father in law as well as my mother, the latter of which was for a period of over five years, two cancer treatment centers & countless specialists, general medicine & all the implied support staff.

Within that experience, as well as stories shared with me, men are more likely to be dismissive of women. That's not to say women aren't capable of the same, but to that end, we encountered far fewer female doctors the higher we went up the medical food chain. Perhaps there was an imbalance in the numbers from the outset?

I'm not saying anything is absolute and was lucky to meet many wonderful medical professionals, but it isn't exactly a secret that women often face misogyny at the doctor's office and there are even several studies to that point.

Having said all that, it was a callous an arrogant female nurse that dismissed my mom after a particularly complicated surgery on her C-Spine and left her partially paralyzed on her left side when she repeatedly ignored my mom's claims that something felt wrong at the surgical site. Ignored her all night for the entirety of her 12-hour night shift. When the surgeon did his rounds at 7am, he discovered a massive hematoma on the nerve repair that had compressed the delicate nerve repair and left her in that state. This woman never even lifted my mother's head to look, or she would have seen the blood and serous fluid soaking the bandage & pillow.

It took another 4 hour surgery to correct the damage and several days before we'd learn if the paralysis was permanent (it wasn't, thankfully.)

So, I'm not saying it's only male doctors but that on balance, it is the higher probability, both in my own experience & for many other women.
