Purpose. To determine whether there is a difference between the perfor
mances of women and men students in the study of obstetrics and gyneco
logy. Method. 127 students in the classes of 1996 and 1997 at the UMDN
J-School of Osteopathic Medicine studied obstetrics and gynecology as
part of a four-week module on human reproduction in the fall of their
second year. The module was followed by an 80-question multiple-choice
examination. In their third year, the students rotated through a six-
week clinical clerkship, during which they were scored on many aspects
of their work, including relationships with patients. The present stu
dy examined by gender the students' overall clerkship scores, their ab
ility to relate to patients, and their performances on the multiple-ch
oice examination. Results. No significant difference between the score
s of the women students and the men students were found for the module
's multiple-choice examination or for the clerkship's score on relatio
nships with patients. However, the women scored significantly better t
han the men in the clerkship's overall score. Conclusion. The women st
udents clearly outperformed the men students during the clinical clerk
ship on obstetrics and gynecology. The reasons for this are not immedi
ately apparent. Further investigation is necessary.
