Ultrastructural study of spermatogenesis in KSR2 deficient mice.

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
The aim of this study was to investigate the spermatogenesis in ksr2(-/-) mice. Spermatogenesis in 12-15 week-old C57BL/6 wt and ksr2(-/-) mice was observed in testicular tissue and epididymal sperm by light and transmission electron microscopy. The reproductive capacity of male ksr2(-/-) mice was strongly impaired. Concentration, morphology and motility of epididymal spermatozoa were altered in ksr2(-/-) mice. In seminiferous tubules from ksr2(-/-) mice, all stages of spermatogenetic process were represented; spermatids displayed defects concerning nuclear and acrosomal shape and periaxonemal structures of the tail; detached head and spermatozoa with an altered head-tail connection were observed; the interstitial tissue was severely disorganized, the Leydig cells have lost their connections. TEM analysis of epididymal spermatozoa confirmed the presence of such kind of alterations. We reported, for the first time, an ultrastructural study of ksr2(-/-) mice spermatogenesis. Remarkable findings regard the altered spermiogenetic process concomitant with a severe disorganization of interstitial tissue. Further studies are needed to assess the ksr2(-/-) mice hormonal status, focussing on testosterone levels since the interstitial tissue, where the Leydig cells reside, was compromised.
