The impact of tucking on fertility among transgender women: A systematic review.
Review in International journal of transgender health, 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
Introduction: Tucking involves maneuvering the testicles into the inguinal canal and compressing one's penis and scrotum posteriorly for a smoother pelvic area. A study based in Baltimore reports that 74.7% of transgender women engage in this practice. Objectives: Fertility preservation is a significant concern for many transgender women, however, the implications of tucking on fertility remain underexplored. This review aims to bridge this knowledge gap. Methods: Using PRIMSA guidelines, a systematic search across various databases was conducted to identify studies evaluating the impact of genital tucking on fertility. Keywords related to tucking, transgender identity, and fertility were utilized. Results: In total, 127 manuscripts were identified, of which 11 satisfied the inclusion and exclusion criteria. Four studies noted significant differences in semen parameters between cisgender men and transgender women prior to gender-affirming hormone therapy suggesting tucking as a potential factor. Two studies documented tucking prior to semen analysis but did not establish a definitive link between tucking and lower semen parameters in transgender women. One study, with a larger sample size of 113 transgender women, discovered an odds ratio of 7.95 between extensive tucking and low total motile sperm count. One year-long study on daily tucking reported a decline of up to 98% in total motile sperm count, and a complementary paper noted an increase in abnormal sperm morphology. Two case reports observed that after a 3-4 month cessation from tucking, semen parameters returned to normal. Conclusion: The review highlights the prevalence of tucking among transgender women and the negative impact on fertility it may have. Temporary cessation of tucking may improve semen parameters for fertility preservation. A harm reduction approach should be implemented to balance fertility aspirations with the management of gender dysphoria.
