Use of Pentoxifylline to Improve Seminal Parameters in Dogs. [PDF]
Vet Med SciA single oral dose of pentoxifylline (10 mg/kg) administered 40 min before ejaculation significantly improved sperm concentration and progressive motility in dogs. The effect was most pronounced in oligospermic subjects, supporting pentoxifylline as a rapid, well‐tolerated adjunct therapy for canine subfertility .

Progesterone significantly enhances the mobility of boar spermatozoa [PDF]
, 2013 Progesterone released from the cumulus cells of the oocyte causes a number of physiological responses in human sperm cells including hyperactivation, acrosome reaction and chemotaxis. We employed a validated sperm mobility assay, which involves measuring

CaMKIIalpha interacts with multi-PDZ domain protein MUPP1 in spermatozoa and prevents spontaneous acrosomal exocytosis [PDF]
, 2009 The success of acrosomal exocytosis, a complex process with a variety of inter-related steps, relies on the coordinated interaction of participating signaling molecules.

Genes Regulating Spermatogenesis and Sperm Function Associated With Rare Disorders
Frontiers in Cell and Developmental Biology, 2021 Spermatogenesis is a cell differentiation process that ensures the production of fertilizing sperm, which ultimately fuse with an egg to form a zygote.

The rab3A-22A chimera prevents sperm exocytosis by stabilizing open fusion pores [PDF]
, 2016 At the final stage of exocytotis, a fusion pore opens between the plasma and a secretory vesicle membranes; typically, when the pore dilates the vesicle releases its cargo.

, 2016 The acrosome, a single exocytotic vesicle on the head of sperm, has an essential role in fertilization, but the exact mechanisms by which it facilitates sperm-egg interactions remain unresolved. The acrosome contains dozens of secretory proteins that are packaged into the forming structure during spermatogenesis; many of these proteins are localized ...

Epac, Rap and Rab3 act in concert to mobilize calcium from sperm's acrosome during exocytosis [PDF]
, 2014 BACKGROUND: Exocytosis of sperm's single secretory granule or acrosome (acrosome reaction, AR) is a highly regulated event essential for fertilization. The AR begins with an influx of calcium from the extracellular milieu and continues with the synthesis
