Sex steroid inhibition of LH induction of the LH receptor
estrogen testosterone luteinizing hormone receptor testis Leydig cell
2009/2/23
Testosterone and estrogen were tested as possible mediators of the prolactin-dependent LH induction of LH receptors in hypophysectomized adult male rats. Animals were injected s.c. with saline, pr...
Accessory sex gland function in normal young（20-25 years）and middle-aged（50-55 years）men
Accessory sex gland function normal young（20-25 years） middle-aged（50-55 years）men
2009/2/23
A comparison of various parameters of prostatic and vesicular secretory function was made between the seminal plasma of young (20-25 years; n = 23) and middle-aged (50-55 years; n = 19) male volunte...
Sex steroid-induced changes in collagen of the prostate and seminal vesicle of rats
testosterone propionate cniı yctrotestosterone estradiol prolactin collagen
2009/2/23
The effects of androgen alone or in combination with estrogen or prolactin on the collagen of the prostate and seminal vesicles were studied in prepubertal and adult rats. Castration decreased the c...
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...
Effect of Castration and Androgen Treatment on Sex-Linked Reactivity of Rat Aorta to a Thromboxane-Mimic
castration androgen-treatment vascular reactivity thromboxane-mimic
2009/2/19
In order to examine the possible role of androgens in the isotonic response of the isolated rat aorta, a highly active mimic of thromboxane was employed. The maximum response to this TXA2-mimic U4...
Neuronal nitric oxide synthase in the canine prostate：aging, sex steroid, and pathology correlations
Testis imprinting BPH atrophy testosterone
2009/2/17
Nitric oxide synthase (NOS) is expressed in the prostate of various species, including humans. NOS catalyzes the production of nitric oxide (NO), which may function in prostatic smooth-muscle relaxa...
Comparison of the response of rat testis and accessory sex organs to treatment with testosterone and the synthetic androgen methyltrienolone（R1881）
Androgens spermatogenesis testis prostate
2009/2/17
We have studied the ability of the synthetic androgen methyltrienolone (R1881) to maintain testis and accessory organ weights, as compared to the effect of testosterone propionate (TP). In contrast ...
Fluorescence in situ hybridization analysis of sex-chromosome mosaicism in azoospermic men
Azoospermia chromosome aberration infertility marker
2008/12/29
A retrospective study was carried out to determine the prevalence of sex-chromosome mosaicism among azoospermic men and to evaluate the feasibility of using fluorescence in situ hybridization (FISH)...
Does sperm morphology play a significant role in increased sex chromosomal disomy? A comparison between patients with teratozoospermia and OAT by FISH
Sperm morphology sex chromosomal aneuploidy
2008/12/29
Eight semen samples from men with teratozoospermia (T), along with samples from 3 men with normal fertility and 5 samples from men with oligoasthenoteratozoospermia (OAT) were analyzed for X and Y c...
Influence of sex hormones on prostate volume in men on hemodialysis
sex hormones prostate volume men hemodialysis
2008/12/25
The relationship between sex hormones and prostate volume in 90 men on hemodialysis and 91 healthy men was investigated. In men on hemodialysis, serum levels of total and free testosterone were sign...
