The effects of prolactin (PRL), bromocriptine, testosterone propionate (TP), dihydrotestosterone (DHT), and the combinations of these androgens with PRL or bromocriptine on nucleic acids (RNA and DN...
Reversal of testicular function after prolonged suppression with an LHRH agonist in rhesus monkeys
testicular function prolonged suppression LHRH agonist rhesus monkeys
2009/2/23
Using subcutaneously implanted osmotic pumps, four male rhesus monkeys were continuously infused for 18 months with 100 micrograms/day of [(imBzl)-D-His6-Pro9-NEt]-LHRH (LHRH-A), a potent agonist of...
Testicular and serum testosterone variations in squirrel monkeys during seasonal cyclicity
serum testosterone variations squirrel monkeys seasonal cyclicity
2009/2/23
The seasonal testicular maturation of squirrel monkeys (Saimiri sciureus) was used as a model of maturational hormonal regulation of the testis. Testicular testosterone and serum testosterone concen...
Testicular blood flow and fluid dynamics in monkeys with surgically induced varicoceles
varicocele monkey testicular blood flow
2009/2/19
The blood flow rates and ability to remove an added fluid load were studied in the testes of monkeys with surgically induced varicoceles and in sham-operated control monkeys. These studies were conduc...
Effects of Chronic, High-dose LHRH-Agonist Treatment on Pituitary and Testicular Functions in Rhesus Monkeys
Chronic High-dose LHRH-Agonist Treatment Pituitary Testicular Functions Rhesus Monkeys
2009/2/18
The effects of chronic, high-dose treatment with an LHRH-agonist (D-Ser-(TBu)6-LHRH-ethylamide) on pituitary and testicular functions were investigated in four adult rhesus monkeys in-season. Doses ...
Pharmacokinetics of 7 alpha-methyl-19-nortestosterone in men and cynomolgus monkeys
MCR SHBG replacement therapy male
2009/2/17
Testosterone and its esters are widely used for androgen replacement therapy. In the prostate, testosterone ins 5 alpha-reduced to dihydrotestosterone (DHT), which leads to an amplification of its...
Effects of castration and recombinant human inhibin administration on circulating levels of inhibin and gonadotropins in adult male monkeys
castration recombinant human inhibin administration circulating levels inhibin gonadotropins adult male monkeys
2009/2/12
Inhibin has been suggested to play a role in gonadal feedback regulation of follicle-stimulating hormone (FSH) secretion; however, neither the half-life nor the time course of action of recombinan...
Alterations in sperm characteristics of follicle-stimulating hormone（FSH）-immunized men are similar to those of FSH-deprived infertile male bonnet monkeys

2008/12/25
The quality of sperm ejaculated by bonnet monkeys and normal, healthy proven fertile volunteer men, both actively immunized with ovine follicle-stimulating hormone (oFSH), was examined at different ...
Expression of Orphan Receptors TR2, TR3, TR4, and p53 in Heat-Treated Testis of Cynomolgus Monkeys（Macaca fascicularis）
