Preliminary evaluation of the effect of dutasteride on PCA3 in post-DRE urine sediments: a randomized, open-label, parallel-group pilot study.

30 Oct 2009 BACKGROUND: Dutasteride is commonly used in patients that are also at risk for prostate cancer (PCa). Therefore, the influence of dutasteride on PCa markers has to be studied. To date, only the effect of dutasteride on serum prostate-specific ... Read more...

Prostate cancer: a newly discovered route for testosterone to reach the prostate : Treatment by super-selective intraprostatic androgen deprivation.

29 Sep 2009 The prostate, an androgen-regulated exocrine gland, is an integral part of the male reproductive system which has an essential function in sperm survival and motility in its long hostile route to meet and fertilise the egg in the Fallopian tube. ... Read more...

Hypogonadism-related symptoms: development and evaluation of an empirically derived self-rating instrument (HRS 'Hypogonadism Related Symptom Scale').

29 Sep 2009 While self-report screening instruments are highly sensitive to hypogonadism in the ageing male, they have lacked specificity as evidenced by low or absent correlations with testosterone. The purpose of this paper was to develop an economical and ... Read more...

Technical information about 'Testosterone'

Definition: A potent androgenic steroid and major product secreted by the LEYDIG CELLS of the TESTIS. Its production is stimulated by LUTEINIZING HORMONE from the PITUITARY GLAND. In turn, testosterone exerts feedback control of the pituitary LH and FSH secretion. Depending on the tissues, testosterone can be further converted to DIHYDROTESTOSTERONE or ESTRADIOL.
