New Biological Insights on X and Y Chromosome-Bearing Spermatozoa
A spermatozoon is a male germ cell capable of fertilizing an oocyte and carries genetic information for determining the sex of the offspring. It comprises autosomes and an X (X spermatozoa) or a Y chromosome (Y spermatozoa).

The relationship between seminal plasma aspartate aminotransferase activity, sperm osmotic resistance test value, and semen quality in boars [PDF]
The relationship between the activity of aspartate aminotransferase (AspAT) in seminal plasma and the values of the osmotic resistance test (ORT) of acrosomal membranes and semen traits was examined on 120 young hybrid Pietrain and Duroc boars.

Spermatozoa collected from the cauda epididymis of wild ruminants are more cryoresistant than ejaculated spermatozoa. Changes in the membrane location of aquaporins (AQPs) follow the osmotic changes that occur during freeze-thawing, and might influence ...

Increased frequency of aneuploidy in long-lived spermatozoa. [PDF]
Aneuploidy commonly causes spontaneous abortions, stillbirths, and aneuploid births in humans. Notably, the majority of sex chromosome aneuploidies in live births have a paternal origin.

Epigenetic Alterations in Cryopreserved Human Spermatozoa: Suspected Potential Functional Defects
Background: Gene set enrichment analysis (GSEA) was conducted on raw data, and alternative splicing (AS) events were found after mRNA sequencing of human spermatozoa.

Chemotaxis of Arbacia punctulata spermatozoa to resact, a peptide from the egg jelly layer [PDF]
Resact, a peptide of known sequence isolated from the jelly layer of Arbacia punctulata eggs, is a potent chemoattractant for A. punctulata spermatozoa. The chemotactic response is concentration dependent, is abolished by pretreatment of the spermatozoa ...

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