long- and short-term vasectomy structural and functional parameters rat
2009/2/20
The effects of vasectomy were examined by comparing various parameters from sham operated and vasectomized rats that had undergone surgery at 90 days of age and were killed at 190 or 390 days of age...

The effectiveness of intratesticularly injected bacille Calmette Guérin (BCG) as an antispermatogenic agent was examined by light microscopy in rats after three, six, ten, twenty, and 56 days and in...
Vitamin E deficiency causes incomplete spermatogenesis and affects the structural differentiation of epithelial cells of the epididymis in the rat
Vitamin E structural differentiation epithelial cells epididymis rat
2009/2/17
The effects of vitamin E deficiency on the rat testis and epididymis were examined in a light- and electron-microscopic analysis. Various groups of animals were made vitamin E-deficient, beginning...

Sperm structural motility changes Brown Norway rat
2008/12/26
The Brown Norway rat provides a useful model to study aging of the male reproductive tract because of the selective age-dependent pathological changes that are found in the testis, epididymis, and pro...
Structural Characterization and Expression Studies of Dby and Its Homologs in the Mouse
Ddx3 D1Pas1 3'-UTR gonad spermatogonia spermatocytes spermatids
2008/12/24
In spite of recent evidence showing the importance of DBY (DEAD-box RNA helicase Y) in spermatogenesis in human, the biologic role of its homolog Dby (also known as Ddx3y) in the mouse is less clear...
