GnRH-A induced arrest of spermiogenesis in rats is associated with altered androgen binding protein distribution in the testis and epididymis
GnRH-antagonist Sertoli cell spermatogenesis
2009/2/10
This study examines the effects of a potent gonadotropin releasing hormone (GnRH)-antagonist (GnRH-A, Ac-D[2] Nal1, 4-CL-D Phe2, D-Trp3, D-Arg6, D-Ala10) upon the distribution of androgen binding pr...
Stage-specific expression of a protein of the acrosome of baboon sperm during spermiogenesis detected with a monoclonal antibody
Spermatogenesis spermiogenesis acrosome monoclonal antibody
2009/2/7
A single monoclonal antibody, BSA4, raised against baboon epididymal sperm was used to study the ontogeny of the baboon sperm acrosome region during testicular spermiogenesis. This antibody is not s...
Altered protamine 2 expression is uncommon in donors of known fertility, but common among men with poor fertilizing capacity, and may reflect other abnormalities of spermiogenesis
Semen sperm chromatin fertilization IVF infertility
2008/12/29
During the spermatid elongation stage of spermiogenesis approximately 85% of sperm nuclear histones are replaced by protamines. Protamines increase the packing ratio of sperm chromatin, presumably fac...
Cellular Localization of GABA and GABAB Receptor Subunit Proteins During Spermiogenesis in Rat Testis
Spermatid immunocytochemistry acrosome GABAergic system
2008/12/23
The GABAergic system, a major inhibitory regulator in the central nervous system, may also play important roles in peripheral nonneuronal tissues and cells. Recent studies showed that GABAB receptor...
