A cohort study is an observational study where a group of individuals (cohort) is followed over time to observe the development of specific outcomes. These studies can be prospective, where participants are followed from the present into the future, or retrospective, utilizing existing data to look back in time. In gynecology, cohort studies often investigate the association between exposures such as hormonal treatments, lifestyle factors, or genetic predispositions and outcomes like reproductive health, cancer, and other gynecological disorders.
