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...
