Cooling 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...
متن کاملCryopreservation and fertility of ejaculated and epididymal stallion sperm.
The cryopreservation of epididymal sperm is important to preserve genetic material from valuable deceased males. This study evaluated the viability of sperm samples from eight stallions under three conditions: (1) collected using an artificial vagina (EJ-0h), (2) recovered from the epididymal cauda immediately after orchiectomy (EP-0h), and (3) recovered from the epididymal cauda after 24h of s...
متن کاملCaspase activity and apoptotic markers in ejaculated human sperm.
The objectives of this study were to determine if human ejaculated sperm exhibit active caspases and if caspase-dependent apoptosis markers are identifiable. Sperm from fertile donors and infertile patients were examined after gradient separation into leukocyte-free fractions of high and low motility. Sperm were evaluated for motion parameters, morphology, caspase activation, and apoptosis mark...
متن کاملEjaculated Mouse Sperm Enter Cumulus-Oocyte Complexes More Efficiently In Vitro than Epididymal Sperm
The mouse is an established and popular animal model for studying reproductive biology. Epididymal mouse sperm, which lack exposure to secretions of male accessory glands and do not precisely represent ejaculated sperm for the study of sperm functions, have been almost exclusively used in studies. We compared ejaculated and epididymal sperm in an in vitro fertilization setting to examine whethe...
متن کاملA comparison of electroejaculation and epididymal sperm collection techniques in stallions.
The purpose of this study was to evaluate 2 methods of semen collection that could be used as terminal procedures in stallions with irreparable conditions, such as fractures or colic. Electroejaculation was attempted under general anesthesia. Forty-eight hours later, the ponies were castrated and 2 different epididymal sperm collection techniques were attempted by using a flushing or floating m...
