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 کاملP-34: Effect of Glucose on Buffalo Epididymal Sperm Motion Characteristics, Viability and Cytoplsmic droplets During 24 Hours Incubation
Background: The recovery of sperm from the cauda epididymis may be the last chance to conserve, genetic Materials of valuable farm animals. Sperm utilize glucose as source of energy through glycolysis and oxidative phosphorylation to provide motility and movement. While endogenous glucose of the culture media has little potential to preserve sperm motility and viability for long period of time ...
متن کاملChanges in hyaluronidase, acrosin, and N-acetylhexosaminidase activities of dog sperm after incubation.
Hyaluronidase, acrosin and N-acetylhexosaminidase activities were examined in sperm collected from 12 beagle dogs and in culture medium after 0.5 hr and 7 hr of sperm incubation. The activities of the three enzymes were significantly higher at 7 hr than at 0.5 hr (P < 0.05, 0.01), and the increases were associated with sperm capacitation. It was considered that the three enzymes in the dog sper...
متن کاملSuperior clinical pregnancy rates after microsurgical epididymal sperm aspiration
Purpose To assess normal fertilization, clinical pregnancy, and live birth rates after the use of microscopic epididymal sperm aspiration (MESA). Methods One-hundred-and-sixty azoospermic participants who underwent MESA were evaluated. The MESA was performed by using a micropuncture method with a micropipette. In cases in which motile sperm were not obtained after the MESA, conventional or mi...
متن کاملCooling of ejaculated and epididymal stallion sperm
After a serious injury or sudden death, epididymis cauda sperm recovery and cryopreservation may present as the last opportunity to obtain genetic material from a valuable stallion. This study evaluated the viability of cooled equine sperm collected by three different methods: sperm of ejaculated (G1), sperm recovered from the epididymal cauda immediately after orchiectomy (G2) and sperm recove...
