Effect of hepatitis B virus infection in males on pregnancy outcomes of intrauterine insemination.
Article in Scientific reports, 2025. 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
China has a high prevalence of the hepatitis B virus (HBV), and many patients seeking assisted reproductive technologies are infected. This study investigated the relationship between male HBV infection and intrauterine insemination (IUI) outcomes. We retrospectively analyzed 1,686 IUI cycles performed at the Assisted Reproductive Center of Zhongshan City People's Hospital from January 2015 to September 2023. Couples in which the male partner was HBV-infected and the female partner uninfected comprised the study group, while couples in which neither partner was infected formed the control group. Propensity score matching ensured comparability between groups, yielding 88 cycles in the study group and 311 in the control group. Post-matching analysis revealed no significant differences in hCG positivity rate, clinical pregnancy rate, preterm birth rate, low birth weight rate, mean birth weight, or gender ratio (P > 0.05). However, early pregnancy loss was significantly higher in the HBV-infective group compared to the HBV-uninfective group (43.75% vs. 14.00%, P < 0.05). Generalized estimating equation analysis confirmed that male HBV infection increased the risk of early pregnancy loss (adjusted OR = 7.022; 95% CI 1.889-26.100; P < 0.05). Our results suggest that male HBV infection is associated with a higher rate of early pregnancy loss.
