2009/2/20
In Vitro binding and some binding parameters of the glycosaminoglycan heparin to viable epididymal or ejaculated bull spermatozoa, ejaculated rabbit spermatozoa, and frozen-thawed rhesus monkey sper...
The binding patterns of antisera to sex steroids and human gonadotropins on human and rhesus monkey spermatozoa
human spermatozoa monkey spermatozoa hormone binding sites immunofluorescence steroids
2009/2/20
The presence of different hormones on the surface of ejaculated spermatozoa was determined by immunofluorescence studies of the binding patterns of specific antisera to these hormones. There were st...
Ultrastructure and Maturational Changes in Spermatozoa in the Epididymis of the Pigtailed Monkey, Macaca nemestrina
ultrastructure sperm maturation spermatozoa epididymis monkey epididymal sperm
2009/2/19
Ultrastructural characteristics of the acrosome, postacrosomal region, plasma membrane, and cytoplasmic droplet in spermatozoa taken from the caput, corpus, and cauda epididymidis of the pigtailed...
Early Ultrastructural Findings in Experimentally Produced Varicocele in the Monkey Testis
varicocele monkey testicular morphology electron microscopy adrenal metabolites
2009/2/19
Varicocele was produced in adult male macaque monkeys (Macaca fascicularis) by partial occlusion of the left renal vein. Left varicoceie was verified by palpation. An increase in temperature of the ...
Estradiol and high-dose dihydrotestosterone treatment causes changes in cynomolgus monkey prostate volume and histology identical to those caused by testosterone alone
Male transrectal ultrasonography androgens estrogens
2009/2/18
To evaluate the effects of testosterone (T), dihydrotestosterone (DHT), and estradiol (E2) on the regulation of prostate growth and tissue composition, the following study was conducted in a nonhuma...
Evidence that in a physiological setting Sertoli cell number is the major determinant of circulating concentrations of inhibin B in the adult male rhesus monkey（Macaca mulatta）
Sertoli cell number circulating concentrations inhibin B adult male rhesus monkey
2009/2/18
The relationship between changes in Sertoli cell number and function and changes in circulating inhibin B concentrations was investigated following unilateral orchidectomy (UO) in the adult rhesus...
Cloning and characterization of an androgen-dependent acidic epididymal glycoprotein/CRISP1-like protein from the monkey
Gutknecht J Brew K Spur N. Goodfellow PN. Cloning
2009/2/18
A cDNA encoding an acidic epididymal glycoprotein (AEG)-like, CRISP1 (cysteine-rich secretory protein) protein from the monkey (Macaca mullata) epididymis has been cloned and sequenced. The monkey A...
TGF-beta could be involved in paracrine actions in the epididymis of the marmoset monkey（Callithrix jacchus）
TGF-beta paracrine actions epididymis marmoset monkey
2009/2/18
The transforming growth factor-beta1 (TGF-beta1) and the transforming growth factor-beta receptor type II (TGF-betaRII) were studied in the epididymis of sexually mature marmoset monkeys (Callithrix...
Effect of acute androgen withdrawal by GnRH antagonist on epididymal sperm motility and morphology in the cynomolgus monkey
acute androgen withdrawal GnRH epididymal sperm motility
2009/2/18
Hormonal male contraception requires an induction phase before azoospermia and contraceptive safety are achieved. The nature of spermatozoa that may be ejaculated during this induction phase was s...
