MTCA‐Net: Multi‐Task Cascade Analysis Network for Real‐Time Sperm Quality Analysis

open access: yesAdvanced Intelligent Systems, EarlyView.
This article proposes MTCA‐Net, a multi‐task cascaded analysis network for real‐time sperm quality assessment in intracytoplasmic sperm injection. The framework integrates detection, tracking, and segmentation modules to jointly analyze sperm morphology and motility.

REVIEW: Current Status of Extenders and Cryoprotectants on Fish Spermatozoa Cryopreservation [PDF]

open access: yes, 2005
An important component of many studies of cryopreservation of fish spermatozoa is the type of extenders and cryoprotectants. The suitability of extenders and cryoprotectants differs from one fish to another.

Low-Cost QCM Sensor System for Screening Semen Samples [PDF]

open access: yes, 2010
Artificial insemination is a well-established part of modern agricultural practice. A viable semen sample is judged by the total number of spermatozoa (sperm) in the sample and the motility of the sperm.

Differences in ATP Generation Via Glycolysis and Oxidative Phosphorylation and Relationships with Sperm Motility in Mouse Species*

open access: yesJournal of Biological Chemistry, 2015
Background: Sperm from mouse species may produce ATP through glycolysis or respiration. Results: Sperm with high respiration/glycolysis ratio and high reliance on respiration produce more ATP and swim faster. Conclusion: The usage ratio of ATP production

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates

open access: yesThe Anatomical Record, EarlyView.
Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

Sperm DNA fragmentation and oxidation are independent of malondialdheyde

open access: yesReproductive Biology and Endocrinology, 2011
Background There is clinical evidence to show that sperm DNA damage could be a marker of sperm quality and extensive data exist on the relationship between DNA damage and male fertility status.

Modulation of the asymmetry of sea urchin sperm flagellar bending by calmodulin [PDF]

open access: yes, 1985
Sea urchin spermatozoa demembranated with Triton X-100 in the presence of EGTA, termed potentially asymmetric, generate asymmetric bending waves in reactivation solutions containing EGTA. After they are converted to the potentially symmetric condition by

The Semen pH Affects Sperm Motility and Capacitation

open access: yesPLoS ONE, 2015
As the chemical environment of semen can have a profound effect on sperm quality, we examined the effect of pH on the motility, viability and capacitation of human sperm. The sperm in this study was collected from healthy males to avoid interference from

Ursolic Acid Alleviates Orchitis via Modulating Ferroptosis in Peritubular Myoid Cells of Testis

open access: yesAnimal Research and One Health, EarlyView.
Ursolic acid modulates key ferroptosis‐related pathways in the peritubular myoid cells of the testis in forest musk deer. ABSTRACT Chronic stress adversely affects reproductive health, increasing susceptibility to pathologies such as orchitis. Additionally, the maintenance of iron homeostasis is essential for preserving the function of the testicles ...

An miR-200 Cluster on Chromosome 23 Regulates Sperm Motility in Zebrafish [PDF]

open access: yes, 2018
Besides its well-documented roles in cell proliferation, apoptosis, and carcinogenesis, the function of the p53-microRNA axis has been recently revealed in the reproductive system.
