There “are”. But for most of medicine’s history there “weren’t”.

And men were making decisions about things they simply had no idea about.

Using the same analogy, then all veterinarians are sadistic?

Your claim simply can't be explained with historical data. Women have entered the medical field for decades upon decades.

What has advancements in medical equipment and diagnostics have to do with women studying to become physicians? Pharmacology and medical equipment is an industry.

Further: [..]Historically, medical studies have excluded female participants and research data have been collected from males and generalized to females. The gender gap in medical research, alongside overarching misogyny, results in real-life disadvantages for female patients.[..]

Because even in the 70s gynecologist practices were already significantly changing due to women doctors entering the field. Claiming that something so easily changed isn't done because "the entire field of gynecology is founded upon intentional sadistic torture of women by male physicians" is totally ridiculous. It's so far divorced from reality that it's lands you in troll territory.
