Comparison of Intrauterine Insemination Success Rates Using Donor Sperm Between Heterosexual and Female Couples: A Retrospective Cohort Study.
Article in JBRA assisted reproduction, 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
objectiveTo compare the success rates of intrauterine insemination with donated sperm between heterosexual and female couples.
methodsThis was a retrospective cohort study involving 519 women who underwent intrauterine insemination with donated sperm over a 5-year period. The sample included 193 women in heterosexual relationships and 326 women in female relationships. Participants were between 18 and 38 years old, undergoing their first reproductive treatment, and had no known female fertility disorders.
resultsNo significant differences were found between the two groups in reproductive outcomes. Positive pregnancy test rates were 35.8% for heterosexual couples and 29.1% for female couples (p=0.12). Ongoing pregnancy rates were 31.6% and 27.3%, respectively (p=0.37). Live birth rates were 29.5% for heterosexual couples and 24.8% for female couples (p=0.2).
conclusionsThis study found no significant differences in intrauterine insemination with donated sperm outcomes between heterosexual and female couples. These findings suggest that the absence of seminal fluid exposure in female couples may not negatively impact reproductive success. However, the role of immune tolerance in assisted reproduction outcomes remains unclear. Further multicenter studies with larger samples are needed to explore the potential influence of seminal fluid and possible clinical interventions that may replicate its effects.
