The Surprise Truths & Myths About Fertility, Menstruation, the Placenta and COVID-19. Expert Guest: Dr Viki Male In this episode we explore and debunk the myth that vaccines cause infertility. But we have a surprising finding about COVID-19 infection and fertility. Tune in, to hear more. Dr Viki Male is a senior lecturer in reproductive immunology based in the Department of Metabolism, Digestion and Reproduction at Imperial College London. She did her PhD at the University of Cambridge on a particular kind of cell called natural killer cells in human pregnancy. During the pandemic, she was involved in collating and communicating information on the effect of SARS-CoV2 infection and COVID-19 vaccination on fertility, pregnancy, and breastfeeding. She also conducted research on how COVID-19 vaccination affects the menstrual cycle. We will explore some of these areas with her and answer some of our listeners' questions on this topic.

Yes, but the changes are small and cycles quickly return to normal.   References for the association of menstrual cycle length with COVID-19 and COVID-19 vaccination: Edelman, Alison et al. “Timing of Coronavirus Disease 2019 (COVID-19) Vaccination and Effects on Menstrual Cycle Changes.” Obstetrics and gynecology 143,4 (2024): 585-594. doi:10.1097/AOG.0000000000005550 Edelman, Alison et al. “Association between menstrual cycle length and covid-19 vaccination: global, retrospective cohort study of prospectively collected data.” BMJ medicine 1,1 (2022): e000297. doi:10.1136/bmjmed-2022-000297 Alvergne, Alexandra et al. “Associations Among Menstrual Cycle Length, Coronavirus Disease 2019 (COVID-19), and Vaccination.” Obstetrics and gynecology 143,1 (2024): 83-91. doi:10.1097/AOG.0000000000005343 Darney, Blair G et al. “Impact of coronavirus disease 2019 (COVID-19) vaccination on menstrual bleeding quantity: An observational cohort study.” BJOG : an international journal of obstetrics and gynaecology 130,7 (2023): 803-812. doi:10.1111/1471-0528.17471 Wesselink, Amelia K et al. “COVID-19 vaccination and menstrual cycle characteristics: A prospective cohort study.” Vaccine 41,29 (2023): 4327-4334. doi:10.1016/j.vaccine.2023.06.012 References for how COVID-19 vaccine does not affect fertility: Zaçe D, La Gatta E, Petrella L, Di Pietro ML.
