Dioxin-Induced Changes in Epididymal Sperm Count and Spermatogenesis
A single in utero exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) on gestation day 15 decreased epididymal sperm count in adult rats and thus was used to establish a tolerable daily intake for TCDD. However, several laboratories have been unable to replicate these findings. Moreover, conflicting reports of TCDD effects on daily sperm production suggest that spermatogenesis may not be as ...
متن کاملMorphological and acrosomal changes of canine spermatozoa during epididymal transit
BACKGROUND During epididymal transit, functional and structural modifications leading to full maturation enable male gametes to reach, recognize and fertilize the oocytes. In dogs, little is known on the modifications of spermatozoa during the passage in the epididymis. The aim of this study was to describe the motility, morphology and acrosomal patterns of canine spermatozoa retrieved from the...
متن کاملPlasmalogen in ram semen, and its role in sperm metabolism.
Whole semen can be stored successfully under both aerobic and anaerobic conditions, owing to the presence of glycolysable carbohydrate in the seminal plasma. However, if mammalian spermatozoa are separated from the seminal plasma by centrifuging and washing, they can maintain their motility only in the presence of oxygen. From this it has been inferred that when spermatozoa are deprived of fruc...
متن کاملLeptin Receptor in Ram Epididymal Spermatozoa
This experiment was designed to investigate leptin receptors (Ob-R and Ob-Rb) mRNA in ram epididymal spermatozoa by RT-PCR. Ten testes were obtained from abattoir and epididymal spermatozoa recovery was performed. To purify spermatozoa, motile sperm were isolated by the swim-up procedure. Total RNA was isolated from epididymal spermatozoa and placental cotyledon, as a positive control, and then...
