China Family Planning Association (CFPA) is promoting sexual health among men who have sex with men, which has led to their improved sexual health practices and behaviour.
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...
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...
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 ...
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...
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...
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...
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 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...
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...
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...
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 ...
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)...
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...
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...
