About this study
Official title: Retrospective Study of COVID-19 on Reproductive Function and Assisted Reproductive Technology Pregnancy Outcome in China
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.
Read the detailed description
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.

| Study group | Role | What they receive |
|---|---|---|
| Infertile couples from the research center who visited for fertility disorders | Infertile couples infected or not infected with COVID-19 were included.This is an observational study with no interventions. Receives: Other: no intervention |
What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: 3 months
Secondary outcomes (2)
Clinical and laboratory indicators related to male and female reproductive function
AMH, INB, sex hormone, follicle output rate, Gn days, total Gn, endometrial thickness on the embryo transfer day, semen quality; Oocyte maturation rate, fertilization rate, high-level embryo rate, blastocyst formation rate
Measured: 3 months
Outcome indicators of assisted pregnancy
Embryo implantation rate, early abortion rate, ongoing pregnancy rate, incidence of OHSS
Measured: 3 months

Questions about this trial
What is this clinical trial studying?
An observational study of COVID-19, run by Jinling Hospital, China at 3 sites in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 31 Jan 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Bing Yao, PHD (025-80864609, yaobing@nju.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Ongoing pregnancy rate (time frame: 3 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05685966, which also lists 15 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Jan 2023.
