A research was carried out in Shanghai involving 177 females of childbearing age who had tested positive for COVID-19. The purpose was to explore if having SARS-CoV-2 infection influences menstrual cycles and sex hormone levels.

Women pregnant, breastfeeding or suffering from previous menstrual issues were not included in the study.

In women with severe COVID-19 symptoms, longer menstrual cycles occurred more frequently than in those with mild symptoms. However, no significant differences were identified regarding sex hormones between healthy individuals and coronavirus patients during the study period.

Within a span of one to two months post infection:
84% of participants reported regularization of bleeding volume, while normal rhythm resumed for all but 1% concerning their monthly periods after being infected by the virus. No substantial evidence about disruptions due to vaccination against COVID-19 related to women’s menstrual functions emerged during this research phase yet.
The British Medicines and Healthcare products Regulatory Authority (MHRA) have shared reports of altered menstrual bleeding after COVID-19 vaccination, but there is no proven connection between the vaccine and an increased risk for unforeseen bleeding. Similar occurrences have been noted with other vaccines like flu or HPV shots. After receiving the vaccine, menstrual disturbances lasted from one to two months in some individuals. Although current research does not link infertility or getting pregnant with taking the COVID-19 vaccine, it’s crucial to rule out pregnancy if your period stops or its pattern changes during infection recovery before pursuing diagnostics due to various potential causes of menstrual disorders.
