Seminal Plasma Heparin Binding Proteins Improve Semen Quality by Reducing Oxidative Stress during Cryopreservation of Cattle Bull Semen [PDF]
Heparin binding proteins (HBPs) are produced by accessory glands. These are secreted into the seminal fluid, bind to the spermatozoa at the time of ejaculation, favour capacitation, acrosome reaction, and alter the immune system response toward the sperm.

Multiple Roles of Protamine Kinase SRPK1 and Phosphatase PP1γ in Sperm Development
ABSTRACT Protein phosphorylation regulates key events of male germ cell differentiation. In the testis, SRPK1 and PP1γ are involved in protamine phosphorylation and dephosphorylation, respectively, and their deregulation is linked to defective chromatin structure and male infertility.

Osteopontin enhances sperm capacitation and in vitro fertilization efficiency in boars
In this study, we used more reliable experimental materials and methods to detect the effects of osteopontin (OPN) on boar sperm in vitro capacitation, acrosome reaction, and fertilization efficiency.

ABSTRACT Background More than 1000 genes have been identified as predominantly expressed in the human testis. Advances in gene editing technologies have enabled the rapid and efficient generation of genetically engineered mice. This approach facilitates the screening of genes essential for spermatogenesis by analyzing knockout mouse models.

In vitro Induction and Detection of Acrosomal Exocytosis in Human Spermatozoa
The acrosome reaction is a highly regulated exocytotic event that primes spermatozoa for successful fertilization. Upon induction, acrosomal exocytosis proceeds via a wave of vesiculation that radiates across the sperm head, destabilizing the acrosomal ...

IN VITRO BUFFALO SPERM CAPACITATION WITH SPECIAL ATTENTION TO ACROSOME REACTION AND OOCYTE PENETRATION TEST [PDF]
In vitro Buffalo sperm capacitation and assessment of acrosome reaction by using Nigrosin-Eosin-Gemisa(NEG) staining technique were performed. Sperm capacitation was done by TALP capacitation media with different concentrations of heparin.

ABSTRACT Background Asthenozoospermia is a significant contributing factor to male infertility. Accumulating evidence indicates that impaired sperm motility is closely linked to dysregulated microRNA expression during spermatogenesis. Seminal plasma exosomes are enriched with diverse microRNAs, which play pivotal roles in modulating sperm motility, the
