Since graduating from med school almost 30 yrs ago, the class size at my alma mater has not changed. The class composition has changed from 5% women to ~50% women. The average length of career (time from start of practice to retirement) for women is on the order of half the length for men. There are all the usual and predictable reasons for this. This has effectively decreased the pool of practicing physicians by about 25%. No sexism here; just statistics.
You’d think that since women are now going into medical school, we’d have twice as many qualified applicants, and they could double their enrollment without sacrificing quality.
