Women receive 40-45% of the degrees in math and statistics, but less than 20% of degrees in CS. The percentage of CS degrees degrees awarded to women is down from 30% in the mid 1990s.

There is no rational "biological" explanation for why women would somehow be "biologically" averse to CS while pursuing degrees in a closely related field at much higher numbers. There is no "biological" explanation why women's interest in CS would drop dramatically over just a few decades.
