1 · What the graph read from it

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.

2 · The registry

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

backgroundA mixture of spermatozoa and accessory gland secretions (from seminal vesicles, prostates, and coagulating glands) is ejaculated into the female reproductive tract at copulation. However, the physiological function of accessory glands on male fecundity remains unclear.

methodsPublications regarding the physiological functions of male accessory glands were summarized. MAIN FINDINGS

resultsThe functions of accessory glands have been studied using male rodents surgically removed coagulating glands (CG), prostates (PR), or seminal vesicles (SV). CG-removed males are fertile or subfertile, while the fecundity of PR-removed males is controversial. SV-removed males show copulatory plug defects, leading to fewer sperm in the uterus and severe subfertility. TGM4, SVS2, and PATE4 were identified as essential factors for copulatory plug formation. When the sufficient number of epididymal spermatozoa was artificially injected into a uterus (AI method), they could efficiently fertilize oocytes, implicating that accessory gland secretions are not essential. Seminal vesicle secretions (SVSs) improved fertilization rates only when low numbers of spermatozoa were used for AI. The changes of uterine environment by SVSs could not improve the pregnancy rate.

conclusionAccessory gland factors are critical for copulatory plug formation and support sperm fertilizing ability.
