Context: Since the 1980s, the age at which U.S. teenagers, especially minority youth, begin having sex has decreased. There is limited information on the relationship between early sexual initiation a...
Circadian variation in testosterone, sex hormone-binding globulin, and calculated non-sex hormone-binding globulin bound testosterone in healthy young and elderly men
Circadian variation testosterone sex hormone-binding globulin healthy young and elderly men
2009/2/23
The circadian pattern in levels of serum total testosterone (T) in men becomes blunted with normal aging. However, because T not bound to sex hormone-binding globulin (non-SHBG-T) is felt to be a be...
Study of the accuracy of physical and biochemical markers in semen to detect infectious dysfunction of the accessory sex glands
male infertility semen analysis semen biochemistry prostatitis acid phosphatase gamma-glutamyltranspeptidase
2009/2/23
Infection of the male accessory sex glands may result in impaired secretory function and alteration of the composition of seminal plasma. Using receiver operating characteristic curves and accuracy ...
Serum levels of total testosterone and sex hormone binding globulin in hypothyroid patients and normal subjects treated with incremental doses of L-T4 or L-T3
testosterone SHBG thyroid hormone hypothyroidism
2009/2/23
Plasma testosterone (T) and sex hormone binding globulin (SHBG) were assayed in normal controls (N = 9) and hypothyroid patients (N = 17) receiving increasing doses of L-T4 (0.2 mg, 0.4 mg for 30 da...
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 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...
