Selected Pathologies of the Male Genital Organs in Bulls, Including Frequency, Significance, and Risk Factors: A Review.
Review in Animals : an open access journal from MDPI, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Bulls can develop various conditions affecting the penis, testicles, and associated structures that reduce fertility, spread disease, and increase costs for farmers. This review synthesizes data from farm fertility examinations and slaughterhouse findings to illustrate the prevalence of these conditions, their causes (including inherited defects, infections, and injuries), their impacts on breeding, and potential interventions. Conditions discussed include orchitis, testicular hypoplasia, testicular degeneration, testicular hydrocele, malignant tumors, spermatocele, penile papillomatosis, and penile hematoma. Lameness and systemic illnesses can also impair a bull's breeding ability. Regular fertility examinations assessing overall health, testicle size, semen motility, and sperm morphology, coupled with timely medical or surgical treatment, can improve reproductive outcomes. Maintaining national records of birth defects and health histories could aid in preventing the transmission of deleterious traits. Reducing these disorders enhances animal welfare, protects herd fertility and the food supply, and supports the economic viability of cattle producers.
