Stimulation of sperm production by human chorionic gonadotropin after prolonged gonadotropin suppression in normal men
sperm production human chorionic gonadotropin prolonged gonadotropin suppression normal men
2009/2/20
The precise hormonal milieu required for quantitatively normal spermatogenesis in man is unclear. The authors previously have shown that both supraphysiologic dosages of human chorionic gonadotropin...
Seminal vesicles are novel sites of luteinizing hormone/human chorionic gonadotropin-receptor gene expression
LH/hCG receptors male accessory organs gonadotropins
2009/2/17
The hypothesis that rat seminal vesicles may contain luteinizing hormone (LH)/human chorionic gonadotropin (hCG) receptors was tested by means of a number of different techniques. Northern blotting ...
Human chorionic gonadotropin but not the calcitonin gene-related peptide induces postnatal testicular descent in mice
Cryptorchidism mechanisms androgens paracnne factors gonadotropins testes
2009/2/13
The androgen-regulated paracrine factor, calcitonin gene-related peptide (CGRP), has been proposed as a possible mediator of testicular descent. This peptide has been found to increase rhythmic co...
Differential actions of gonadotropin-releasing hormone and human chorionic gonadotropin on interstitial fluid volume and immunoglobulin G concentrations in adult rat testis
gonadotropin-releasing hormone human chorionic gonadotropin interstitial fluid volume immunoglobulin G concentrations adult rat testis
2008/12/25
Gonadotropin-releasing hormone (GnRH) agonists regulate testicular interstitial fluid (tIF) volume, most probably via specific receptors on Leydig cells. The aim of this study was to confirm the int...

Activation of the steroidogenic machinery by peptide hormones involves a number of steps for transmitting signals from the plasma membrane to mitochondria in a spatially and temporally coordinated...
Induction of Spermatogenesis by Recombinant Follicle-Stimulating Hormone（Puregon）in Hypogonadotropic Azoospermic Men Who Failed to Respond to Human Chorionic Gonadotropin Alone
Follistim gonadotrophin deficiency male infertility testis
2008/12/19
A multicenter, open-label, randomized efficacy and safety study was performed with combined human chorionic gonadotropin (hCG) and recombinant follicle-stimulating hormone (recFSH) (Puregon®) ...
