AMP-activated kinase AMPK is expressed in boar spermatozoa and regulates motility. [PDF]

PLoS ONE, 2012
The main functions of spermatozoa required for fertilization are dependent on the energy status and metabolism. AMP-activated kinase, AMPK, acts a sensor and regulator of cell metabolism. As AMPK studies have been focused on somatic cells, our aim was to

EFFECT OF HESPERETIN TREATMENT ON BLOOD GLUCOSE LEVEL, SPERMATOZOA QUALITY, AND SPERMATOZOA QUANTITY IN ALLOXAN-INDUCED DIABETIC MICE

Jurnal Kedokteran Hewan, 2021
Male infertility has occurred rapidly in the last few decades, primarily in developing countries. An antioxidant, hesperetin is a flavonoid that is found in abundance in orange peels.

Doing more with less: the flagellar end piece enhances the propulsive effectiveness of human spermatozoa [PDF]

Phys. Rev. Fluids 5, 073101 (2020), 2019
Spermatozoa self-propel by propagating bending waves along a predominantly active elastic flagellum. The organized structure of the "9 + 2" axoneme is lost in the most-distal few microns of the flagellum, and therefore this region is unlikely to have the ability to generate active bending; as such it has been largely neglected in biophysical studies ...

Immunogenicity of human spermatozoa [PDF]

, 2008
Investigation and experimental design of the study was basically aimed at developing insight into the antigenicity of spermatozoa-associated proteins. Apart from studying the natural antigenicity of washed whole spermatozoa, their immunogenicity was also

Hydrogen sulfide repairs testicular damage induced by heat stress in rats

FEBS Open Bio, EarlyView.
Heat stress can cause testicular damage and affect fertility. We investigated the potential protective role of hydrogen sulfide (H2S) against heat stress‐induced testicular injury and observed that H2S donor NaHS can effectively restore testicular damage in rats by inhibiting inflammation and oxidative stress. Our results suggest that H2S might be used

Identification of Sialyl-Lewis(x)-Interacting Protein on Human Spermatozoa

Frontiers in Cell and Developmental Biology, 2021
Capacitated spermatozoa initiate fertilization by binding to the zona pellucida (ZP). Defective spermatozoa-ZP binding causes infertility. The sialyl-Lewis(x) (SLeX) sequence is the most abundant terminal sequence on the glycans of human ZP glycoproteins

Collection and freezing of equine epididymal spermatozoa [PDF]

, 2014
The epididymis and vas deferens store an important number of fertile spermatozoa called the extragonadal sperm reserves. These stored spermatozoa can be collected in an ultimate attempt to preserve viable spermatozoa of a critically ill or dying stallion.

Possible role of human ribonuclease dicer in the regulation of R loops

FEBS Open Bio, EarlyView.
R loops play an important role in regulating key cellular processes such as replication, transcription, centromere stabilization, or control of telomere length. However, the unscheduled accumulation of R loops can cause many diseases, including cancer, and neurodegenerative or inflammatory disorders. Interestingly, accumulating data indicate a possible

Addition of Cryoprotectant DMSO Reduces Damage to Spermatozoa of Yellow Catfish (Pelteobagrus fulvidraco) during Cryopreservation: Ultrastructural Damage, Oxidative Damage and DNA Damage

Animals
Spermatozoa cryopreservation protocols have been established for yellow catfish (Pelteobagrus fulvidraco), but cryopreservation can still cause cellular damage and affect spermatozoa viability and fertility.
