Origin of a motility inhibitor within the male reproductive tract
motility inhibitor male reproductive tract
2009/2/20
Seminal plasma contains a motility inhibitor of demembranated reactivated spermatozoa. We investigated its origin within the reproductive tract. The highest level of inhibitor was detected in semina...
Reproductive tract secretions and bull spermatozoa contain different clusterin isoforms that cluster cells and inhibit complement-induced cytolysis
Epididymal fluid rete testis fluid L-cells
2009/2/18
Clusterin from bull rete testis fluid (RTF), cauda epididymal fluid (CEF), and octyl-beta-D-glucopyranoside extract of cauda epididymal sperm (CES) was identified and characterized using monoclonal ...
Estrogen receptor（alpha and beta）expression in the excurrent ducts of the adult male rat reproductive tract
Efferent ductules immunohistochemistry
2009/2/17
The understanding of estrogen's function in the male reproductive tract is limited, and estrogen receptor (ER) localization in the reproductive tract of the adult male rat has not been described. ...
Catalase mRNA expression in the male rat reproductive tract
Catalase mRNA expression male rat
2009/2/16
Reactive oxygen species (ROS) have been shown to impair sperm function. The actions of ROS are reduced by antioxidant enzymes, including catalase. Although catalase-like activity has been demonstrated...
Suppression of androgen action and the induction of gross abnormalities of the reproductive tract in male rats treated neonatally with diethylstilbestrol
androgen action gross abnormalities reproductive tract male rats diethylstilbestrol
2008/12/26
This study evaluated whether androgen action is altered in rats treated neonatally with diethylstilbestrol (DES) at a dose that induced reproductive tract abnormalities. Rats were treated on alterna...
Osteopontin gene expression in the Holstein bull reproductive tract
Osteopontin gene expression Holstein bull reproductive tract
2008/12/25
The objective of this study was to localize gene expression of osteopontin in the Holstein bull reproductive tract using Northern blot analysis and in situ hybridization. For Northern blot analysi...
Immunohistochemical Localization of Sperm-Preserving Proteins in the Ram Reproductive Tract
Seminal plasma proteins seminal vesicles cold shock ram spermatozoa
2008/12/24
Previously, we reported that the addition of seminal plasma proteins before cold-shock treatment prevents sperm membrane injury, and that 2 proteins of approximately 14 (P14) and 20 (P20) kDa,...
Characterization and Localization of Cysteine-Rich Secretory Protein 3（CRISP-3）in the Human Male Reproductive Tract
CRISP-1 CRISP-2 SGP28 semen prostate fertilization
2008/12/23
Mammalian members of the cysteine-rich secretory protein (CRISP) family are expressed predominantly in the male reproductive tract and are implicated in the process of reproduction from spermiogen...
Neonatal Coadministration of Testosterone With Diethylstilbestrol Prevents Diethylstilbestrol Induction of Most Reproductive Tract Abnormalities in Male Rats
Rete testis efferent ducts vas deferens seminal vesicles androgens estrogens
2008/12/19
The primary purpose of this study was to evaluate whether the coadministration of testosterone (TE; 200 µg) with 10 µg of diethylstilbestrol (DES) between days 2 and 12 postnatally could...
Localization of Androgen and Estrogen Receptors in Adult Male Mouse Reproductive Tract
Efferent ductule epididymis steroid hormone receptors testis vas deferens
2008/12/16
There is considerable variation, both within and between species, in reports of nuclear steroid receptor localizations in the male reproductive tract. In this study, androgen receptor (AR) and estroge...
Host Defense Proteins of the Male Reproductive Tract
Host Defense Proteins Male Reproductive Tract
2008/12/8
Innate immunity, the rapidly responsive and phylogenetically ancient system of host defense, is generating increasing interest in part due to the growing appreciation for its remarkable broad spectrum...
Binding of Protein D/E to the Surface of Rat Epididymal Sperm Before Ejaculation and After Deposition in the Female Reproductive Tract
Epididymal secretory protein interaction sperm plasma membrane
2008/12/5
The objectives of the present investigation were to study the interaction of protein D/E with the surface of rat epididymal spermatozoa and to assess its topology on the spermatozoa surface before a...
