(5) lower spatial intelligence scores, which is concerning in fields that use this e.g. physics, engineering   /1745699 "men with lower t performed better than other groups on measures of spatial/mathematical ability, tasks at which men normally excel. **women with high t scored higher than low-t women on these same measures.** t concentrations did not relate significantly to scores on tests that usually favor women or that do not typically show a sex difference. these results support suggestions of a nonlinear relationship between t concentrations and spatial ability, and demonstrate some task specificity in this respect."   e/article/pii/030645309190018o   21942436   ilanding&doi=10.1037/0012-1649.31.4 .697 "**when mental rotation ability  was statistically adjusted for, the significant gender difference in sat-m was eliminated for the college sample and the high-ability college-bound students. this suggests that spatial ability may be responsible in part for mediating gender differences in math aptitude among these groups**" (in other words, the gap in stem may be accounted for by accounting for testosterone levels.) this article is excellent to read, and describes just how many misconceptions surround testosterone's effect on women:   e/article/pii/s0378512213000121
