COVID-19 has caused lifestyle changes that have affected the menstrual cycle.

“History” A pandemic of coronavirus 2019 (COVID-19) has caused major changes to one's living arrangements and drew significant changes to his work environment and personal life. Using this research, we examined the effect that the COVID-19 pandemic has had on the gender cycle and any factors that may contribute to these changes. 

The questionnaire was completed by 749 participants, who ranged from doing physical activities to being in the elite group in terms of training status. During and prior to the COVID-19 pandemic lockdown period, the questionnaire evaluated the woman's menstrual cycle symptoms and characteristics, as well as her personal lifestyle, stress, exercise, and nutrition. Descriptive statistics and frequency distribution were reported and decision tree analysis performed.

Statistical significance was assumed at p<0.05.During the lockdown period, 52.6% of women reported their menstrual cycle had changed. Significantly fewer participants with changes in psychosocial symptoms had increased stress/worry related to family and personal health. Furthermore, job security measures were associated with more bleeding time (p0.05). Conclusion: "Females and practitioners must become aware of the effects of stressful environments on fertility, particularly of the long-term implications, particularly as the global pandemic continues to unfold."
