polarized monolayers epididymal epithelial cells Sertoli cells dual environment culture chambers
2009/2/23
Epididymal epithelial cells isolated from mature rats and Sertoli cells isolated from 10-day-old rats were cultured in serum-free defined media on extracellular matrix impregnated filters maintained...
Growth and reproductive adaptation in male rats with chronic protein deficiency
protein deficiency undernutrition testicular
2009/2/20
In previous studies, male rats fed a low-protein diet beginning at weaning were found to have impaired sexual development through age 11 weeks when compared to food-restricted, weight-matched contro...
Prolactin-induced Modulation of Tissue Growth Rate Patterns in Albino Rats During Puberal Transition
prolactin growth rate curves tissue somatic indices advancement of puberty accessory male reproductive glands
2009/2/19
The role of prolactin (PRL) in the puberal transition of male albino rats has been investigated. It was found that PRL elevated total organ growth rates, tissue somatic indices, and dry weights of r...
Production of endothelin by canine prostatic epithelial cells and its stimulatory effects on their growth
Canine prostate ETB receptors cell growth
2009/2/18
The current study has been designed to explore expressions of endothelin (ET) receptors and ETs in the canine prostate and the effect of ETs on canine prostatic epithelial cells. ET receptors were c...
Prostatic growth rate determined from MRI data：age-related longitudinal changes
Prostatic growth rate MRI data age-related longitudinal changes
2009/2/18
Men with prostatic enlargement are at highest risk of developing symptomatic lower urinary tract symptoms (LUTS) and related outcomes, such as acute urinary retention. The study of prostatic growt...
Modulation of insulin-like growth factor-1 in the seminal plasma of infertile men
Modulation insulin-like growth factor-1 seminal plasma infertile men
2009/2/18
It has been suggested that insulin-like growth factor (IGF)-1 plays an important role in the regulation of spermatogenesis in the testes. In the present study, concentrations of total IGF-1 we...
Suppression of growth hormone does not affect ongoing spermatogenesis in rats
Suppression of growth hormone ongoing spermatogenesis rats
2009/2/18
Recent evidence suggests that growth hormone (GH) may enhance physiologic processes, such as spermatogenesis, in addition to causing classical anabolic effects. We have previously shown that testost...
Levels of hepatocyte growth factor/scatter factor（HGF/SF）in seminal plasma of patients with andrological diseases
Testis spermatozoa male infertility
2009/2/17
Hepatocyte growth factor/scatter factor (HGF/SF) has all the characteristics of a molecule suitable for functioning in regulatory networks of motility, such as the spermatogenic epithelium, where sper...
Transforming growth factor-beta1（TGF-beta1）in penile and prostate growth in the rat during sexual maturation
Penis androgen receptors
2009/2/17
The goal of this study was to determine whether transforming growth factor-beta1 (TGF-beta1) may contribute to the arrest of penile growth and the down-regulation of androgen receptors (AR) that occ...

Sexual behavior placental growth hormone variant
2009/2/17
Male transgenic (TG) mice overexpressing the human placental growth hormone (GH) variant gene (hGH-V) exhibit reproductive deficits in spite of normal testosterone levels and normal sperm counts. ...
