The effect of COVID-19 infection on the menstrual cycle: a cross-sectional investigation in the MENA region.

Due to the paucity of literature on COVID-19 and menstrual irregularities, this study aims to investigate the effect of COVID-19 infection on menstrual changes in premenopausal women within the Middle East and North Africa (MENA) region. A cross-sectional investigation utilizing a self-administered online questionnaire was conducted between July and August of 2021. A total of 499 females participated in our survey with a mean age of 35.
