This multi-center, retrospective cohort study aimed to determine which factors are associated with ongoing pregnancy rates in infertile patients received ART treatments during the current outbreak of COVID-19 infection.Couples who underwent IVF-ET/ICSI-ET/FET due to infertility in the department of Reproductive Medicine from 2022-11-23 to 2023-01-07 were included. 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.
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.

Ongoing pregnancy rate
If the fetal sac, fetal bud, and primitive fetal heartbeat are found by vaginal B-ultrasound examination 55-65 days after embryo transfer, the diagnosis of ongoing pregnancy will be made.

Time frame: 3 months
Outcome indicators of assisted pregnancy
Embryo implantation rate, early abortion rate, ongoing pregnancy rate, incidence of OHSS
Time frame: 3 months
