The Impact of Long COVID on the Female Reproductive System: A Narrative Review.
Review in International journal of molecular sciences, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Long COVID affects multiple organ systems and disproportionately affects women, raising concerns about reproductive health. This updated narrative review summarizes evidence from PubMed, Scopus, and Web of Science through March 2026 and extends previous reviews by distinguishing Long COVID-specific findings from acute and early post-infection observations and integrating newer evidence on ovarian reserve, follicular-fluid biology, assisted reproduction, and endometrial function. Reported menstrual changes include irregular cycles, heavy or prolonged bleeding, intermenstrual bleeding, and amenorrhea. Evidence regarding ovarian reserve remains inconsistent: some studies reported lower anti-Müllerian hormone (AMH) levels and/or antral follicle count (AFC), whereas others found no significant changes. Case reports describe premature ovarian insufficiency (POI) and possible autoimmune oophoritis but do not establish causality. Proposed mechanisms include immune dysregulation, inflammation, oxidative stress, endothelial dysfunction, and hypothalamic-pituitary-ovarian axis disturbance. Available evidence does not indicate adverse effects of COVID-19 vaccination on ovarian reserve or fertility outcomes. Most studies suggest transient changes. Direct Long COVID-specific evidence for persistent ovarian or endometrial injury remains limited. However, short follow-up precludes conclusions regarding ovarian aging, menopausal timing, lifetime fertility, or long-term endometrial receptivity. Symptom-guided assessment may include menstrual tracking, AMH, early-follicular-phase follicle-stimulating and luteinizing hormones, and pelvic ultrasonography when clinically indicated.
