NCT05562479

Brief Summary

Purpose: To determine the impact of SARS-CoV-2 infection and immunization on ovarian response to controlled ovarian stimulation (COS) and embryo development after in vitro fertilization (IVF) Methods: A retrospective multicentric cohort study of 427 oocyte donors was conducted between January 1st, 2018 and September 18th, 2022. Patients who recovered from SARS-CoV-2 infection, vaccinated or non-exposed were included. Demographic, cycle characteristics, and laboratory outcomes were compared.

Study Population

Patients were categorized into the vaccinated group if they had received two dosages of any SARS-CoV-2 vaccines with a break of at least three weeks between each dose. First and second vaccine dates were requested from vaccinated patients. Vaccine administration details, such as vaccine type, dose, date, manufacturer, and lot number, were collected from immunization records. For recovering patients, the date of an adverse nasopharyngeal COVID polymerase chain reaction (PCR) test was registered. None of the recovering patients were vaccinated with any SARS-CoV-2 vaccine. Both clinics strictly required a negative PCR test for SARS-CoV-2 RNA detection 5 days before oocyte retrieval, except for those patients who were less than 3 months following recovery from SARS-Cov-2 infection. Patients in the control group were selected from medical records before March 2020 to ensure they did not have an infection and were not vaccinated.

You may qualify if:

  • Age: 18 - 32 Years
  • Body Mass Index between 18 and 26
  • AFC: Antral follicular count over 15 in total.
  • AMH: Anti-Mullerian hormone over 2.5
  • Signed consents.
  • Covid vaccines and infection information (for case group).

You may not qualify if:

  • Egg donors with incomplete information of days of stimulation, average dose of gonadotropins, the number of retrieved oocytes, mature oocytes, fertilised oocytes and top-quality embryos obtained.
  • Familial genetic disorders.
  • Menstrual cycle disorders.
  • Polycystic ovary syndrome.
