Expression of TRPV1 as A Heat Sensitive Voltage-Dependent Ion Channel and Oxidative Stress in Sperm Samples of Infertile Men with Varicocele: A Case-Control Study [PDF]
Cell Journal, 2022 Objective: Transient receptor potential vanilloid 1 (TRPV1) is a heat-activated nonselective cation channel that playsimportant role in the spermatogenesis, capacitation, acrosome reaction and sperm/oocyte fusion.

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

EDC IMPACT: Chemical UV filters can affect human sperm function in a progesterone-like manner
Endocrine Connections, 2017 Human sperm cell function must be precisely regulated to achieve natural fertilization. Progesterone released by the cumulus cells surrounding the egg induces a Ca2+ influx into human sperm cells via the CatSper Ca2+-channel and thereby controls sperm ...

JAGGED1 modulates bull spermatozoa acrosome reaction and fertilization
Reproduction and FertilityTo acquire fertilizing ability, mammalian spermatozoa (SPZ) must undergo acrosome reaction, which is associated with protein remodeling and relocation. Previous studies showed that Notch ligand JAGGED1 is relocated from the apical to the post-equatorial ...

Role of cytoskeleton-related proteins in the acrosome reaction of Eriocheir sinensis spermatozoa
BMC Genomic Data, 2023 Cytoskeleton-related proteins are essential for cell shape maintenance and cytoskeleton remodeling. The spermatozoa of Eriocheir sinensis (Chinese mitten crab) have a unique cellular structure, and the mechanism of spermatozoal metamorphosis during the ...
