HHV-6B binds the sperm acrosome.
, 2013 Semen samples were pre-incubated with HHV-6B for one hr followed by incubation with either vehicle or calcium ionophore for 30 min to induce an acrosome reaction (AR).

STUDIES ON THE ACROSOME. II. ACROSOME REACTION IN STARFISH SPERMATOZOA
The Biological Bulletin, 1954 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.

Reproduction in Domestic Animals, Volume 61, Issue 6, June 2026.ABSTRACT In a stallion breeding‐soundness examination, testicular volume may be estimated either from total scrotal width or by measuring the height, width and length of both testes. This study aimed to determine whether testicular morphometric parameters obtained by ultrasonography fluctuate throughout the year, and whether these variations affect ...

Assembly of spermatid acrosome depends on microtubule organization during mammalian spermiogenesis
, 2006 The acrosome is a secretory vesicle attached to the nucleus of the sperm. Our hypothesis is that microtubules participate in the membrane traffic between the Golgi apparatus and acrosome during the first steps of spermatid differentiation.
