Psoroptes ovis Infestation Impairs Sexual Behavior and Reduces Testosterone Levels in Male Rabbits.

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
purposeThis study evaluated the effects of chronic infestation with Psoroptes ovis on sexual behavior, testosterone levels, and physiological parameters in New Zealand male rabbits. P. ovis is a common ectoparasite in domestic rabbits (Oryctolagus cuniculus); however, its impact on physiological parameters and sexual behavior, relevant to reproduction and animal welfare, as well as experimental validity, remains poorly understood.
methodsTwenty-three male rabbits were randomly assigned to control (n = 11) or experimentally infested (n = 12) groups and monitored for 77 days. Behavioral assessments included open-field and sexual behavior tests. Physiological data included serum testosterone, temperature, liver enzymes, and lipid profile.
resultsInfested rabbits showed significant reductions in locomotor activity (- 23.2%), chin marking (- 38.3%), and exploratory activity (- 31.2%). Sexual performance was impaired, with an increase in both reaction time and ejaculation latency, while ejaculations decreased by 30.1% and serum testosterone levels by 58%. No significant changes were found in body weight, food intake, liver enzymes, or lipid markers.
conclusionsThese findings indicate that P. ovis infestation alters behavior and endocrine function in male rabbits, with implications for reproductive health and animal welfare, highlighting the need for early detection and control of ectoparasites in rabbits and underlining the importance that ectoparasitic infections could have on sexual performance in other species.
