Abstract

BACKGROUND

The safety of the COVID-19 inactivated vaccine on pregnancy outcomes in couples undergoing assisted reproductive technology remains uncertain due to limited and speculative evidence. Existing studies primarily focus on the vaccination status of females, with scant information available regarding the vaccination status of male partners. Moreover, there is minimal research tracking live birth outcomes.

OBJECTIVE(S)

The objective of this study was to evaluate the impact of COVID-19 inactivated vaccine administration on the outcomes of in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) cycles in infertile couples in China.

METHODS

This prospective cohort study involved couples undergoing IVF treatment at Sichuan Jinxin Xinan Women & Children's Hospital from August 2021 to September 2022. Based on whether they received vaccination before ovarian stimulation, the couples were divided into the vaccination group and the non-vaccination group. We compared the laboratory parameters and pregnancy outcomes between the two groups.

RESULTS

After performing propensity score matching (PSM), we observed similar live birth rates (41.23% vs. 44.08%, P = 0.555), clinical pregnancy rates (52.61% vs. 54.98%, P = 0.625), biochemical pregnancy (62.56% vs. 63.98%, P = 0.762), and ongoing pregnancy rates (49.76% vs. 51.18%, P = 0.770) between the vaccinated and unvaccinated women. Also, no significant disparities were found in terms of embryo development and…

How strong is the evidence?

Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence.
