Donor sperm IVF pregnancies exhibit elevated risk of new-onset hypertensive disorders: a retrospective cohort study.
Article in Journal of assisted reproduction and genetics, 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
purposeTo evaluate the incidence of new-onset Hypertensive Disorders of Pregnancy (HDP) in donor sperm IVF (DS-IVF) compared with partner sperm IVF (PS-IVF) pregnancies.
methodsWe retrospectively analyzed a total of 855 DS-IVF cycles and 4,816 PS-IVF cycles of pregnancies delivering after 20 weeks' gestation achieved live birth between January 2010 and December 2022. All patients underwent fresh embryo transfer after oocyte retrieval. The incidence of new-onset HDP was compared between the two groups.
resultsThe overall incidence of new-onset HDP was 1.7%, with rates of 2.7% in DS-IVF group and 1.6% in PS-IVF group. Multivariate Analysis of risk factors in the entire cohort identified twin pregnancy (OR, 2.483: 95%CI: 1.649-3.739, P < 0.001), elevated body mass index (BMI) (OR, 1.150: 95%CI: 1.095-1.209, P < 0.001), and the use of donor sperm (OR, 2.063: 95%CI: 1.229-3.463, P = 0.006) as independent risk factors for new-onset HDP. In subgroup analyses of both DS-IVF and PS-IVF cohorts, twin pregnancy [DS-IVF: OR, 2.575: 95%CI: 1.085-6.115, P = 0.032; PS-IVF: OR, 2.454: 95%CI: 1.542-3.906, p < 0.001] and elevated BMI [DS-IVF: OR, 1.152: 95%CI: 1.026-1.292, P = 0.016; PS-IVF: OR, 1.150: 95%CI: 1.089-1.215, p < 0.001] were identified as independent risk factors for new-onset HDP.
conclusionThe use of donor sperm is an independent risk factor for new-onset HDP in IVF-conceived pregnancies.
