RESUMEN
RESEARCH QUESTION: Does SARS-CoV-2 mRNA vaccination affect the ovarian reserve of infertile women undergoing IVF? DESIGN: This was a prospective observational study at a single university-affiliated IVF unit that included infertile women aged 18-44 years who were undergoing IVF/intracytoplasmic sperm injection between November 2020 and September 2021, had received two doses of SARS-CoV-2 mRNA vaccination and had undergone measurement of baseline anti-Müllerian hormone (AMH) concentration within the 12 months preceding their recruitment. AMH concentrations before and after vaccination were evaluated and compared. RESULTS: Overall, 31 women were included in the study. The median AMH concentrations before and after COVID-19 vaccine were comparable (1.7 versus 1.6 g/ml, respectively, Pâ¯=â¯0.96). No correlation was found between the participant's anti-COVID-19 antibody titre and the change in AMH concentration. CONCLUSIONS: SARS-CoV-2 mRNA vaccination does not adversely affect ovarian reserve, as shown by comparing serum AMH concentrations before and after vaccination. These findings may serve as a counselling tool for clinicians to reassure women undergoing fertility treatment that SARS-CoV-2 mRNA vaccination is safe.
