Morphological examination of spermatozoa remains a valuable tool for determining the quality of feline sperm for cryopreservation and/or for use in artificial insemination. Numerous staining techniques have been employed for feline sperm assessment, and several variations have also been reported. Forty-eight domestic cats were castrated and epididymal sperm samples were obtained. Sperm morpholo...

Antioxidants partially ameliorated the negative effects of reactive oxygen species (ROS) produced during cryopreservation. The objective of the present study was to investigate the effect of cysteine and a water-soluble vitamin E analogue on the quality of frozen-thawed epididymal cat spermatozoa. Epididymal spermatozoa were collected from eight male cats and divided into three aliquots; these ...

The mammalian testis and epididymis are responsible for spermatozoa production and maturation, which contributes to male fertility. Predominantly expressed proteins in the testis and epididymis were suggested to be involved in the key functions or pathways in spermatogenesis and sperm maturation. To further investigate these proteins and their associations with sperm, large protein profiles of ...

This study was conducted to investigate the potential effects of α-chlorohydrin (ACH) on epididymal function and antioxidant system in male rats. The test chemical was administered to male rats by gavage at doses of 0, 3, 10, and 30 mg/kg/day for 7 days. Twenty-four male rats were randomly assigned to four experimental groups, with six rats in each group. Spermatotoxicity was assessed by measur...

We previously established that levels of the sperm membrane protein, SP22, are highly correlated with the fertility of sperm from the cauda epididymidis of rats exposed to both epididymal and testicular toxicants, and that a testis-specific SP22 transcript is expressed in postmeiotic germ cells. In this study, polyclonal and monoclonal antibodies were generated to study the expression of SP22 i...

Abstract Infertility is a major cause of economic losses in livestock production systems. Parasitic infections are significant infertility small ruminants. Sericea lespedeza (SL; Lespedeza cuneata) potent anthelmintic sheep and goats. Positive impacts on male fertility have been reported rats rabbits; however, no studies conducted Here, we investigated the effects feeding goats with SL or annua...

Introduction: Busulfan as a chemotherapeutic agent causes testicular germinal epithelium depletion and cytotoxicity in germ cells. The aim of this study was to assess antioxidant status, reactive oxygen species (ROS) generation and apoptosis-related genetic markers of adult male mouse sperm following busulfan treatment. Materials and Methods: Forty adult NMRI mice (30 ± 5 g) were divided...

BACKGROUND Epididymal sperm maturation occurs via interactions between sperm and proteins secreted by the epididymal epithelium. Although this is an important process, the genes that encode the involved proteins remain largely uncharacterized. Previous studies have demonstrated that the genes involved in sperm maturation are regulated by androgen. Spag11a is an epididymal gene that is influence...
