Functional restoration of penis with partial defect by scrotal skin flap.

14 Sep 2009 PURPOSE: We investigated a reconstructive method with better sensory and erectile function for partial penile defects and report our long-term results of surgical correction using scrotal skin flaps. MATERIALS AND METHODS: We retrospectively ... Read more...

Expression and function of ryanodine receptors in rabbit penile corpus cavernosum smooth muscle cells.

30 May 2009 This study aimed to investigate the expression and function of ryanodine receptors (RyRs) in rabbit penile corpus cavernosum smooth muscle (CCSM) cells. New Zealand white rabbit CCSM cells were cultured by primary tissue culture and identified by ... Read more...

The relationship of serum and salivary cortisol levels to male sexual dysfunction as measured by the International Index of Erectile Function.

5 May 2009 To evaluate the biomarkers of sexual function, we investigated the relationship between questionnaire responses and biological hormones such as testosterone (T) and cortisol (F) in serum and saliva. The study population included 105 men aged 30-72 ... Read more...

Technical information about 'Penis'

Definition: The external reproductive organ of males. It is composed of a mass of erectile tissue enclosed in three cylindrical fibrous compartments. Two of the three compartments, the corpus cavernosa, are placed side-by-side along the upper part of the organ. The third compartment below, the corpus spongiosum, houses the urethra.
