It Has Been Widely Assumed (And Often Still Is) That

It has been widely assumed (and often still is) that there are no gender differences in the etiology, symptoms, or treatment responses of physical illnesses because:

A) Medical care and treatment concerning health problems, whether developed during infancy, adolescence, adulthood, or old age, show no differences for females and males
B) Women have been understudied and sex and gender are not considered important variables in the advancement of scientific and medical knowledge
C) Stereotyped attitudes towards women and men, derived from mythological, religious, or sociocultural constructions of women and men had no influence on medical research
D) Women did not get sick as often as men so there was no need to study their issues separately
