However, relaxation of the sphincter is also in part a learned response under voluntary control. The released urine enters the urethra, a tube lined with mucus membrane that conveys the urine to the outside. The male urethra, about 8 in. (20 cm) long, terminates at the tip of the penis...
The Testis The main functions of the male reproductive system are to produce the male sex steroid hormones (androgens), to manufacture the male gametes (spermatozoa), and to deliver these successfully to the female reproductive tract. The testes are anatomically and functionally compartmentalized to ...
Second, the urethral striated sphincter consists of two lateral fascicles separated by an anterior and a posterior strip of connective tissue, which extend from the prostatic urethra (i.e. the part of the urethra which runs though the prostate) to the bulb of the penis. An additional third ...
Male Urethra The male urethra is 8 to 9 inches (200mm) long. It is in the shape of a tube. Its prostatic section is arched in shape. The male urethra is longer than the female one, as it has an additional reproductive function to perform along with the excretion of urine. It is co...
The prostate gland plays an integral role in male reproduction during young adulthood. Its anatomic location, between the bladder and the membranous urethra, means that it is also an important part of the urinary voiding pathway and has a significant bystander effects on urinary function. The ...
The penis consists of several major structures:1 Glans: This is the head of the penis. Urethra: This is the tube through which urine and semen exit the penis. Meatus: This is the opening of the urethra at the tip of the penis.
Epididymitis is swelling of the epididymis, which stores sperm in the testicles. A bacterial infection in the bladder, prostate, or urethra usually causes epididymitis. The prostate is a gland that creates fluid to carry semen out of the urethra. Other causes include chlamydia and gonorrhea, which...
(reservoir) emptying. Ideally, this should be achieved by spontaneous voiding; otherwise, intermittent catheterization is necessary. The native urethra may be an acceptable conduit for this maneuver, although should catheterization of it prove excessively difficult or uncomfortable (preventing patient ...

Transurethral and suprapubic catheterization have both been used to test urethral function in rats; however, it is unknown whether these methods affect urethral function or if the order of catheterization affects the results. The aim of this cross-over designed experiment was to compare the effects ...
