Abstract
Background: With the gradual legalisation of recreational cannabis, associated health effects have received widespread attention, but their association with female infertility remains unclear. The aim of this study was to explore the association between cannabis use and infertility among females of childbearing age in the United States.
Methods: Data were obtained from the National Health and Nutrition Examination Survey 2013-2018; 1694 female participants aged 18-45 years were included. The association between cannabis use and female infertility was analysed by logistic regression analysis. All data were weighted before analysis.
Results: After adjusting for all covariates, former cannabis users demonstrated significantly elevated odds of infertility compared with never-users (odds ratio: 2.04, 95% confidence interval: 1.21-3.43, P = 0.012), whereas current cannabis users exhibited no significant difference in infertility odds relative to never-users. In subgroup analysis, former users aged 18-35 years exhibited higher odds of infertility than never-users (odds ratio: 2.37, 95% confidence interval: 1.11-5.04, P = 0.027); but former cannabis users aged 36-45 years demonstrated no significant difference in infertility odds compared with never-users. Among former cannabis users aged 18-35 years, those with sustained abstinence exceeding 3 years demonstrated significantly elevated odds of infertility compared with never-users (odds ratio: 2.94, 95% confidence interval: 1.29-6.71, P = 0.005). In contrast, individuals with shorter abstinence durations (<3 years) showed no significant difference in infertility odds relative to never-users.
Conclusions: Among females of childbearing age, the odds of infertility was not elevated among current cannabis users compared with never-users, while the odds of infertility was elevated among former users. This relationship between cannabis use and female fertility is more often reflected in the distant term (>3 years of cessation), and this adverse association is more pronounced among females in the most active reproductive years (18-35).
期刊介绍：
Journal of Obstetrics and Gynaecology represents an established forum for the entire field of obstetrics and gynaecology, publishing a broad range of original, peer-reviewed papers, from scientific and clinical research to reviews relevant to practice. It also includes occasional supplements on clinical symposia. The journal is read widely by trainees in our specialty and we acknowledge a major role in education in Obstetrics and Gynaecology. Past and present editors have recognized the difficulties that junior doctors encounter in achieving their first publications and spend time advising authors during their initial attempts at submission. The journal continues to attract a world-wide readership thanks to the emphasis on practical applicability and its excellent record of drawing on an international base of authors.
