目的：调查中国女性年龄相关的血清促卵泡刺激素（follicle-stimulating hormone, FSH）浓度及其与骨密度（bone mineral density, BMD）和骨质疏松症（osteoporosis, OP）患病率之间的关系。 方法：测定699位20~82岁健康的中国女性血清FSH浓度，用DXA (dual-energy-X-ray absorptiometry) 仪测定...
Identification of a potential FSH modulatory protein in human testis and seminal plasma
potential FSH modulatory protein human testis seminal plasma
2009/2/23
A variety of factors capable of inhibiting the in vitro binding of FSH to its receptor have been identified in gonadal tissues from males and females. Interest in these factors has been stimulated b...
Transferrin secretion in response to different modes of FSH stimulation and cycloheximide in superfused Sertoli cell cultures
Transferrin secretion FSH stimulation cycloheximide superfused Sertoli cell cultures
2009/2/23
The influence of different modes of FSH stimulation and cycloheximide on transferrin secretion by rat Sertoli cells was investigated using a superfusion culture system. Sertoli cells from 18-day-old...
Increased plasma and pituitary prolactin concentrations in adult male rats with selective elevation of FSH levels may be explained by reduced testosterone and increased estradiol production
Increased plasma pituitary prolactin concentrations adult male rats
2009/2/23
The roles of testosterone and estradiol in regulating prolactin concentrations were studied in acutely castrated adult male rats receiving subcutaneous Silastic implants of the sex steroids. Testost...
Low molecular weight FSH binding inhibitor in bovine testis
Low molecular weight FSH bovine testis
2009/2/23
Purification of low Mr (less than 5000) inhibitors of FSH binding to receptors has been hampered by their low concentration in tissue extracts and physiologic fluids. The calf testis represents an a...
Changes in serum levels of LH, FSH, prolactin, testosterone, and cortisol associated with season and mating in male pygmy goats
serum levels LH FSH prolactin testosterone cortisol season male pygmy goats
2009/2/20
Four male pygmy goats were used in a study designed to determine the effects of season on serum hormone (luteinizing hormone, follicle stimulating hormone, prolactin, testosterone, and cortisol) l...
Role of the pineal in the alteration of hamster Sertoli cell responsiveness to FSH during testicular regression
pineal hamster Sertoli cells testicular regression short photoperiod optic enucleation
2009/2/20
Testicular regression was induced in adult hamsters by optic enucleation, short photoperiod, or melatonin injections. The melatonin injected group, while undergoing testicular regression, showed a q...
Clinical studies in an adult male patient with “isolated follicle stimulating hormone （FSH）deficiency”
isolated FSH deficiency gonadotropin deficiency hypogonadism infertility FSH deficiency
2009/2/20
Previous reports concerning isolated follicle stimulating hormone (FSH) deficiency and its possible pathogenesis have been conflicting. Both "normal" and "abnormal" FSH response to luteinizing hormone...
