Inhibition of In Vitro Fertilizing Capacity of Cryopreserved Mouse Sperm by Factors Released by Damaged Sperm, and Stimulation by Glutathione
BACKGROUND In vitro fertilization (IVF) of eggs by frozen and thawed C57BL/6J mouse sperm is inhibited by dead sperm and enhanced by preincubation of the sperm in calcium-free medium. In other species, the presence of sperm killed by freezing and thawing has been associated with the generation of hydrogen peroxide. METHODOLOGY/PRINCIPAL FINDINGS The proportion of eggs fertilized by cryopreser...

متن کاملInvestigation of fertilizing capacity of cryopreserved spermatozoa from patients with cancer.
PURPOSE There are few published reports concerning fertilization and pregnancy outcomes achieved with cryopreserved spermatozoa from cancer patients. Controversy exists regarding the value of sperm banking for these patients before therapy, whether the spermatozoa are viable after long-term storage and whether they can fertilize the ovum. We assess fertilization and pregnancy outcomes achieved ...
متن کاملThe roles of the epididymis and prostasomes in the attainment of fertilizing capacity by stallion sperm.
The epididymis is a long, tightly coiled tube within the lumen of which sperm matures. Sperm maturation involves morphological and biochemical changes in the sperm plasma membrane in response to epididymal secretions and their various proteins. Some of these proteins become outer membrane components while others become integral membrane proteins; transfer of some proteins to the sperm plasma me...
متن کاملEvaluation of Fertilizing Capacity of Rabbit Sperm on the Basis of Annexin V-labelled Membrane Changes
The aim of this study was (1) to analy�e fresh intact or differently influenced rabbit sperm samples, using Annexin V–binding method for the detection of membrane phosphatidylserine translocation, and (2) to estimate obtained results in relation to the conceptional rate of rabbit females fertili�ed with semen from different groups. Following sample groups were designed: 1. freshly collected sem...
