Transient Complete Asthenozoospermia

open access: diamondJournal of Human Reproductive Sciences
Limited research exists on the mechanisms underlying asthenozoospermia associated with acquired ciliary dyskinesia. Primary ciliary dyskinesia links respiratory pathology with infertility and provides a basis for a potential mechanism.

Roles of CatSper channels in the pathogenesis of asthenozoospermia and the therapeutic effects of acupuncture-like treatment on asthenozoospermia

open access: goldTheranostics, 2021
Rationale: Idiopathic asthenozoospermia (iAZS) is one of the major causes of male infertility and has no effective therapeutic treatment. Understanding the potential mechanisms that cause it may be helpful in seeking novel targets and treatment strategies for overcoming the problem of low sperm motility in iAZS individuals.

DEFB126 polymorphisms and association with idiopathic asthenozoospermia in China

open access: yesAsian Journal of Andrology, 2022
Idiopathic asthenozoospermia, a common factor in male infertility, is characterized by altered sperm motility function in fresh ejaculate. Although the β-defensin 126 (DEFB126) protein is associated with asthenozoospermia, DEFB126 gene polymorphisms have

Absence of annulus in human asthenozoospermia: Case Report† [PDF]

open access: bronzeHuman Reproduction, 2009
The annulus is a septin-based ring structure located at the junction of the midpiece (MP) and the principal piece (PP) of spermatozoa flagellum. In the mouse, deletion of Septin 4, a structural component of the sperm annulus, prevents annulus formation and leads to MP-PP disjunction, flagellar bending, asthenozoospermia and male sterility. Testis anion

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

open access: goldMolecular 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 ...

Deciphering the role of reactive oxygen species in idiopathic asthenozoospermia [PDF]

open access: yesFrontiers in Endocrinology
Asthenozoospermia is a severe condition characterized by abnormal sperm motility, contributing to 50% of male infertility cases. Idiopathic asthenozoospermia refers to a form of this condition with no identifiable causes through routine clinical ...
