This article reports the proteomic legacy of exposure to the xenobiotic, acrylamide, on the epithelial cell population of the proximal segments of the mouse epididymis. Specifically, adult male mice were administered acrylamide (25 mg/kg bw/day) or vehicle control for five consecutive days before dissection of the epididymis. Epididymal epithelial cells were isolated from the proximal (caput) epididymal segment and subjected to quantitative proteomic analysis using multiplexed tandem mass tag (TMT) labeling coupled to mass spectrometry. Here, we report the data generated by this strategy, including the identification of 4405 caput epididymal epithelial cell proteins, approximately 6.8% of which displayed altered expression in response to acrylamide challenge. Our interpretation and discussion of these data features in the article "Acrylamide modulates the mouse epididymal proteome to drive alterations in the sperm small non-coding RNA profile and dysregulate embryo development".

Characterising body and reproductive morphometry and their association with epididymal sperm quality can contribute to the conservation of sambar deer (Rusa unicolor). Five adult males maintained in captivity at the Getúlio Vargas Zoobotanical Park (Salvador, BA, Brazil) were captured, anaesthetised, and subjected to bilateral orchiectomy as part of a population-control strategy. Body measurements included head circumference, thoracic diameter, total length, withers height, and body weight.

In mammals, sperm formation is completed in the seminiferous tubules within the testis, and sperm maturation occurs during the epididymal transit of the spermatozoa. Sperm morphology drastically changes when abnormal spermatozoa migrate from the testis to the epididymis. Detailed molecular mechanisms for sperm survival in the epididymis have not been determined yet.

The epididymis plays a critical role in sperm maturation, including remodeling the sperm RNA payload. While small RNAs have been extensively studied in this context, the epididymal contribution to larger sperm RNAs, such as mRNAs, remains underexplored. mRNAs were among the first RNA species identified in sperm, yet their functional relevance has remained elusive, largely due to the translational quiescence of mature spermatozoa and the hypothesis that these RNAs are residual by-products of spermatogenesis.

The aim was to evaluate the effectiveness of semen cryopreservation and oocyte vitrification in roe deer as a potential method of gamete preservation for endangered deer species. Sperm were isolated from the cauda epididymis of fourteen bucks ( = 14). The motility measure (CASA) and morphology of fresh semen (FS) and frozen-thawed semen (TS) were compared.

The aim of this study was to compare postoperative complications and long-term clinical efficacy of electrospun composite biomaterial and porcine small intestine submucosa (SIS) patch in open inguinal herniorrhaphy. A prospective, randomized, single-blind, controlled, multicenter study was used to select 172 patients with inguinal hernia who met the inclusion criteria in 3 hospitals. All participants were randomly assigned (1:1) and treated by open inguinal herniorrhaphy.
