Although female neurosurgery residents are increasing, women remain underrepresented in academic leadership. To assess academic productivity differences between male and female neurosurgery residents. We used the Accreditation Council for Graduate Medical Education records to obtain 2021-2022 recognized neurosurgery residency programs. Gender was dichotomized into male/female by male-presenting/female-presenting status. Extracted variables included degrees/fellowships from institutional websites, number of preresidency and total publications from PubMed, and h -indices from Scopus. Extraction occurred from March to July 2022. Residency publication number and h- indices were normalized by postgraduate year. Linear regression analyses were conducted to assess factors associated with numbers of in-residency publications. P < .05 was considered statistically significant. Of 117 accredited programs, 99 had extractable data. Information from 1406 residents (21.6% female) was successfully collected. 19 687 and 3261 publications were evaluated for male residents and female residents, respectively. Male and female residents' median preresidency publication numbers did not significantly differ (M:3.00 [IQR 1.00-8.50] vs F:3.00 [IQR 1.00-7.00], P = .09), nor did their h -indices. However, male residents had significantly higher median residency publications than female residents (M:1.40 [IQR 0.57-3.00] vs F:1.00 [IQR 0.50-2.00], P < .001). On multivariable linear regression, male residents (odds ratio [OR] 2.05, 95% CI 1.68-2.50, P < .001) and residents with more preresidency publications (OR 1.17, 95% CI 1.16-1.18, P < .001) had higher likelihood of publishing more during residency, controlling for other covariates. Without publicly available, self-identified gender designation for each resident, we were limited to review/designate gender based on male-presenting/female-presenting status from gender conventions of names/appearance. Although not an ideal measurement, this helped show that during neurosurgical residency, male residents publish significantly more than female counterparts. Given similar preresidency h- indices and publication records, this is unlikely explained by differences in academic aptitude. In-residency gender barriers to academic productivity must be acknowledged and addressed to improve female representation within academic neurosurgery.
