Possible CMV transmission via intrauterine insemination: case report.
Article in BMC infectious diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundMaternal cytomegalovirus (CMV) infection at conception can cause congenital CMV (cCMV) infection and substantial morbidity. Although CMV screening is mandated for sperm donors, the risk of acquiring CMV from donor sperm is unknown. Experience with HIV may lead clinicians to expect that standard sperm-washing reduces CMV transmission risk for procedures including intrauterine insemination. However, limited data suggests that CMV may differ importantly from other herpesviruses and from HIV after sperm washing. CASE PRESENTATION: A 29-year-old CMV immunoglobulin (Ig)M- and IgG-negative patient underwent intrauterine insemination with a directed donor. The donor was CMV IgM-negative and IgG-positive at the time of donation but had been serum IgM-positive 128 days before donation, and urine CMV PCR-positive 107 days before donation. Following intrauterine insemination, the patient developed clinical evidence of acute CMV infection, CMV viremia, and positive CMV IgM and IgG. The intrauterine insemination did not result in pregnancy. No sources of CMV transmission other than intrauterine insemination could be identified.
conclusionsBecause screening and prevention options for perinatal CMV transmission are limited, a systematic research agenda to understand and reduce CMV transmission risk from seropositive sperm donors is needed to create clear guidelines for fertility treatments and support shared decision-making. Novel approaches to lower risk of transmission from sperm donors with detectable CMV IgG should also be further evaluated. These might include CMV DNA testing of washed sperm samples prior to fertility treatments, antiviral therapy prior to semen collection and/or CMV PCR or IgM screening in pregnant patients who conceived using sperm from antibody-positive donors.
