Association between antinuclear antibody and female infertility: A meta-analysis.

Abstract

Autoimmunity is reported involving in reproductive failures, and antinuclear antibody (ANA) positivity has been regarded as a typical feature of autoimmunity. Published studies on the association of ANA with reproductive failures including infertility are controversial. The aim of this meta-analysis was to analyse whether the presence of ANA positivity increases the risk of infertility in women. We searched the PubMed and Embase databases for relevant literature without any restrictions prior to April 28, 2021. All analyses were performed using the RevMan 5.3 software. Twelve studies with 2734 participants, including 1482 patients with infertility, met the inclusion and exclusion criteria. The total positivity rate of ANA was 23.8% (353/1482) in all infertile patients and 8.5% (107/1252) in the control group. Infertile females had a significantly higher ANA positivity rate than the control group (odds ratio [OR] = 2.90, 95% confidence interval [CI]: 1.72-4.87, I
