In this multi-center, retrospective cohort study, we included patients who underwent
IVF-ET/ICSI-ET/FET due to infertility in the department of Reproductive Medicine from
2022-11-23 to 2023-01-07. Patients who were infected with Coronavirus were observation
groups; the infection status and clinical outcome were tracked. Patients who were not
infected with Coronavirus were control groups. We compared different parameters between
two groups. The primary outcome was ongoing pregnancy rate. Basic information about
patients' menstruation, sexual desire, and sexual function were collected from Medical
record system. Other information about patients' vaccination status, symptoms related to
viral infection were collected by telephone follow ups. Susceptibility indicators to
COVID-19 infection including fasting blood glucose, insulin, blood lipids,
alpha-function, renin-angiotensinase, I-aldosterone were obtained . Reproductive function
indices AMH, INHB, sex hormones, follicle retrieval rate, Gn days, total Gn, endometrial
thickness, the incidence of OHSS, semen quality, oocyte maturation rate, fertilization
rate, qualified embryo rate, blastocyst formation rate, and other laboratory indices of
both men and women were also collected . Assisted pregnancy outcome: clinical pregnancy
rate, embryo implantation rate, early abortion rate, ongoing pregnancy rate, and other
clinical indicators were analyzed to determine whether there is deference in clinical
outcomes between two groups.
