CD147 deficiency is associated with impairedsperm motility/acrosome reaction and offersa therapeutic target for asthenozoospermia [PDF]

open access: yesMolecular Therapy: Nucleic Acids, 2021
Patients with asthenozoospermia often present multiple defects in sperm functions apart from a decrease in sperm motility. However, the etiological factors underlying these multifaceted defects remain mostly unexplored, which may lead to unnecessary ...

Effect of phosphodiesterase type 5 inhibitors on sperm motility and acrosome reaction: An in vitro study [PDF]

open access: yesInvestigative and Clinical Urology, 2021
Purpose: Phosphodiesterase type 5 (PDE5) inhibitors are effective treatments for erectile dysfunction, and several recent studies have reported positive effects of PDE5 inhibitors on semen parameters as well. However, the data are still controversial. We

Glycogen Synthase Kinase-3 Regulates Sperm Motility and Acrosome Reaction via Affecting Energy Metabolism in Goats [PDF]

open access: yesFrontiers in Physiology, 2019
Hyperactivation and acrosome reaction of sperm are pre-requisite steps for fertilization. However, the hyperactivation and acrosome reaction are critically controlled through the phosphorylation of specific proteins.

Effect of Lepidium meyenii on in vitro fertilization via improvement in acrosome reaction and motility of mouse and human sperm [PDF]

open access: yesReproductive Medicine and Biology, 2019
Purpose The direct effects of Lepidium meyenii (Maca) on sperm remain unclear. Herein, we examined the direct effect of Maca on in vitro fertilization. Methods We examined the fertilization rate in a mouse model and the rate of acrosome reaction in sperm

The biochemistry of the acrosome reaction [PDF]

open access: yesMolecular Human Reproduction, 1997
The binding of the spermatozoon to the oocyte zona pellucida (ZP) occurs via specific receptors localized over the anterior head region of the spermatozoon. Zona pellucida binding stimulates the spermatozoa to undergo the acrosome reaction resulting in the release of hydrolytic enzymes and in the exposure of new membrane domains, both of which are ...

The Modulation of Functional Status of Bovine Spermatozoa by Progesterone

open access: yesAnimals, 2021
The aim of this study is to identify the effects of progesterone (PRG) on the capacitation and the acrosome reaction in bovine spermatozoa. The fresh sperm samples were incubated with and without capacitation inductors (heparin, dibutyryl cyclic ...
