Is there an increased risk of preeclampsia using donor sperm, depending on sexual condition?
Article in JBRA assisted reproduction, 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
objectiveAn increased risk of preeclampsia has been described when performing donor intrauterine insemination. One of the possible causes is immunological tolerance to semen. Both lesbian and single women, who have theoretically lower exposure to seminal fluid than heterosexual women requesting artificial insemination with donor, sperm should have a higher incidence of preeclampsia, although this fact has not been analyzed previously.
methodsThe population under study consisted of 439 gestations <24 weeks, achieved with artificial insemination with donor sperm, performed in two different populations: heterosexual couples and SLTG (single women, lesbian women, women with transgender partner). Preeclampsia rates and other perinatal outcomes were compared.
resultsNo significant differences were found in the development of preeclampsia in the SLTG group 6.03% (12/199) vs. heterosexual patients 5.83% (14/240), p=0.93. In the SLTG group, compared with heterosexual group, age (36 vs. 35, p=0.002) and BMI (24.8 vs. 23.6, p=0.002) were somewhat higher. After adjusting for BMI, age and multiplicity of gestation, there were no significant differences in the risk of preeclampsia between SLTG group and heterosexual women. As expected, in women with preeclampsia, gestational ages and newborn weights (quantitative markers of preeclampsia severity) were significantly lower than in women without preeclampsia.
conclusionsOur study suggests that neither sexual orientation nor previous sperm exposure carries a higher risk of preeclampsia, especially after correction for age and weight. Artificial insemination with donor sperm performed on single women, lesbians or women with transgender partners is a safe, simple and efficient technique, just as in heterosexual couples.
