Exon 1 of AR gene contains a variable number of CAG triplets, which encode a polyglutamine stretch of variable length in the N-terminal domain of the receptor. Experimental evidence has accumulated in demonstrating that the length of this stretch influences AR transcriptional activity and therefore modulates target organs responsiveness to androgens. Aim of our study was to evaluate CAG repeats length [(CAGr)n] in various conditions hypothetically influenced by AR function. 35...

Hypogonadism is still a poorly-defined clinical entity. Recently approved and published guidelines to diagnosis and treatment of hypogonadism claim the necessity of accompanying biochemical thresholds with clinical symptoms and monitoring under treatment a specific aspect of the ‘wide spectrum’ hypogonadism (libido, erection, bone mass, muscle strength and so on). This is due both to different levels of thresholds for different tissues and to individual variability.<...

Exon 1 of the androgen receptor (AR) gene contains a variable number of CAG triplets, (CAGr)n which encode a polyglutamine stretch of variable length in the N-terminal domain of the receptor. Experimental evidence has accumulated in demonstrating that the length of this stretch influences the transcriptional activity induced by the AR and therefore modulates target organs responsiveness to androgens.The (CAGr)n is inversely associated with the transcript...

Radioiodine-131 is commonly used for treatment of hyperthyroidism, however the effects on testis function are not known. This prompted us to study testis function in hyperthyroid men after 131I treatment. 15 hyperthyroid patients scheduled for 131I treatment underwent: testis US, hormone assessment and sperm analysis before and 45 days, 3, 6 and 10–15 months after 131I. The control group (for testis volume and semen analysis) was constitut...
