Semen, blood serum and morphometric data were collected from Honamli and Hair bucks. Semen samples were evaluated spermatologically and separated for seminal plasma collection, while blood samples obtained on the first and last collection days were processed for serum and stored at –20°C. ABSTRACT Background Breed‐related differences in spermatological

STUDIES ON THE ACROSOME. II. ACROSOME REACTION IN STARFISH SPERMATOZOA
1. When the spermatozoa of three starfish species, Asterina pectinifera, Asterias amurensis and Astropecten scoparius, are suspended in a dilute (0.1-1.0%) solution of egg albumin in sea water and mixed with homologous egg-water, three effects can be noted:a. many of the spermatozoa are agglutinated by their heads, forming permanent clusters;b.

This study reported the effect of Mito‐TEMPO on rooster semen quality cryopreserved in Beltsville extender. Semen diluted in extenders containing 10 or 100 µM of Mito‐TEMPO presented higher motility, average path velocity as well as membrane/acrosome integrity, mitochondrial activity, and fertility rate; and lower lipid peroxidation, apoptosis rate ...

Sperm cells/heads from within the crop of a third instar larva. ABSTRACT Sexual assaults including unwanted sexual touching and rape are continuously occurring within England and Wales, despite police intervention. Furthermore, as seen within recent media reports, these types of offenses can occur immediately prior to homicide.

Testis‐Enriched F‐Box Protein FBXO39 Is Important for Spermiogenesis and Male Fertility in Mice
ABSTRACT Background The SCF (Skp–Cullin–F‐box) complex is a major class of E3 ubiquitin ligases. F‐box proteins constitute the SCF complex and play a critical role in recognizing substrates for ubiquitination. In mice, several F‐box proteins, including FBXO36 and FBXO39, are predominantly expressed in testes.

Improvement of Mouse Spermatozoa Freezing at −80°C With Ascorbic Acid 2‐Glucoside at Thawing Phase
ABSTRACT Background Sperm cryopreservation is the most common method to maintain a great number of mutant mouse lines. However, the use of liquid nitrogen (LN2) for freezing presents considerable problems in terms of cost, safety, and accessibility. For this reason, the storage of semen samples at ‐80° in ultra‐freezers has been increasingly used in ...
