Vasopressin receptors in human seminal vesicles：identification, pharmacologic characterization, and comparison with the vasopressin receptors present in the human kidney
Vasopressin receptors human seminal vesicles identification pharmacologic characterization
2009/2/23
Because of the presence of a high density of vasopressin receptors in the epithelial cells of porcine seminal vesicles similar to the V2 vasopressin receptors of renal tubules, human seminal vesicle...
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...
Age-related changes in the concentration of cytosolic androgen receptors in the epididymis, vas deferens and seminal vesicle of maturing male mice
Age-related changes cytosolic androgen receptors epididymis
2009/2/23
In this study, changes in the number of androgen binding sites that occur in cytosols of epididymis, vas deferens and seminal vesicle of mice from 10 to 90 days of age are described. Specific satura...
Indomethacin and oxaprozin lower seminal prostaglandin levels but do not influence sperm motion characteristics and serum hormones of young healthy men in a placebo-controlled double-blind trial
seminal prostaglandin levels sperm motion characteristics serum hormones young healthy men
2009/2/23
To evaluate the influence of indomethacin and oxaprozin on reproductive function in healthy young men, 34 volunteers with normal semen parameters were recruited. In a randomized double-blind design,...
Can the fertility potential of a seminal sample be predicted accurately?
fertility potential seminal sample
2009/2/23
This paper highlights the most critical aspects of the problem of predicting fertility. To determine if a laboratory test(s) is highly correlated with fertility it is essential to have: a) specific,...
Purification and characterization of a sperm motility inhibitor in human seminal plasma
sperm motility inhibitor human seminal plasma
2009/2/23
A sperm motility inhibitor from human seminal plasma was purified and characterized. The purification procedure includes dialysis, ion exchange chromatography on SP-Sephadex C-25 and adsorption chro...
Measurement of seminal LDH-X and transferrin in normal and infertile men
seminal LDH-X transferrin normal and infertile men
2009/2/23
LDH-X, an isoenzyme of lactate dehydrogenase specific for germinal epithelium activity, has been measured in the seminal plasma of infertile subjects whose infertility had different origins. In the ...
Interactions of androgens and prolactin in the seminal vesicles of mature bonnet monkeys, Macaca radiata. I. Nucleic acids and phosphatases
androgens prolactin seminal vesicles mature bonnet monkeys
2009/2/23
The effects of prolactin (PRL), bromocriptine, testosterone propionate (TP), dihydrotestosterone (DHT), and the combinations of these androgens with PRL or bromocriptine on nucleic acids (RNA and DN...
Comparison between proteinases of human seminal plasma and of sperm origin
proteinases human seminal plasma sperm origin
2009/2/23
A comparison of the alkaline proteinase activity of human seminal plasma, the seminal non-gamete cellular material and spermatozoa was made by gelatin-sodium dodecyl sulfate-polyacrylamide gel elect...
Seminal carnitine content in obstructive azoospermia. Correlation with the anatomic level of obstruction
carnitine obstructive azoospermia epididymal
2009/2/23
Free carnitine in human semen originates predominantly in the epididymis. The role of carnitine in the evaluation of different forms of obstructive azoospermia was studied in 42 patients. In 14 of t...
Possible significance of transferrin levels in seminal plasma of fertile and infertile men
seminal transferrin FSH fertility man
2009/2/23
Human seminal plasma contains large amounts of transferrin, which is a protein secreted mostly by Sertoli cells. It has been suggested that the concentration of transferrin may serve as a possible c...
