Protein phosphatase PP1γ2 in sperm morphogenesis and epididymal initiation of sperm motility
The serine/threonine phosphatase (PP1) isoform PP1γ2, predominantly expressed in the testis, is a key enzyme in spermatozoa. High PP1γ2 catalytic activity holds motility in check in immature spermatozoa. Inhibition of PP1γ2 causes motility initiation in immature spermatozoa and motility stimulation and changes in flagellar beat parameters in mature spermatozoa. The PP1γ2 isoform is present in a...
متن کاملConcentrations of sperm, protein and a sperm membrane glycoprotein within boar epididymal luminal fluids.
Boar rete testis fluid and luminal contents from nine epididymal segments were collected for analysis. From proximal to distal, segments were designated A, B, C (caput), Da, Db, Ea (corpus) and Eb, Fa, Fb (cauda). Concentrations of sperm, protein and soluble sperm membrane glycoprotein S2P3 were lowest in the caput epididymidis (region A) and highest in the proximal corpus epididymidis (region ...
متن کاملBull Fertility and Its Relation with Density Gradient Selected Sperm
Background sperm selection is generally used to describe methods for separation of spermatozoa for in-vitro-assisted reproduction. Few studies reported relation in vivo fertility and semen parameters after selection of fertile spermatozoa; hence, our research attempt to assess different semen parameters after post-thaw (PT) or after selecting sperm sample (SSp), using density gradient separatio...
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...
متن کاملMicrosurgical vasovasostomy versus microsurgical epididymal sperm aspiration/testicular extraction of sperm combined with intracytoplasmic sperm injection. A cost-benefit analysis.
PURPOSE Vasovasostomy (VVS) represents the standard therapy of choice for the treatment of obstructive azoospermia following vasectomy. However, recently, intracytoplasmic sperm injection (ICSI) has been suggested by some to represent the solution for all cases of malefactor infertility regardless of its etiology based on its success rates. Therefore, we compared VVS to microsurgical epididymal...
