to prevent sperm release. Knots, thermal scarring or clips most commonly used.
Reversal of a Vasectomy has a low success rate.
Functions of the Seminal Gland (Vessicle) - answer-;1. Secrete alkaline fluid to
moderate pH of ejaulatory duct and acid from epididymis.
2. Produce fructose for energy for sperm.
3. Produce prostaglandins to stimulate muscular contractions in female
reproductive tract to help move sperm.
Note: Released at emission.
Prostaglandins - answer-;Hormones produced by the seminal gland that causes
peristalsis that pushes the sperm to the egg.
Functions of the Prostate Gland - answer-;1. Secrete alkaline fluid to moderate pH
of acid from epididymis and in vagina.
2. Activates sperm.
When is prostatic fluid released? - answer-;Prostatic fluid is released at emission
when it joins sperm from the vas deferens and seminal fluid.
PATHOLOGY NOTE:
,What is Prostate Hyperplasia? - answer-;Prostate hyperplasia is an enlargement

temperature (3*C/5*F) below body temperature via movements of smooth
muscle.

2. Corporus spongiosum
3. Penile urethra
4. Glans penis
5. Prepuce (foreskin)
Function of the Corporus Cavernosum - answer-;Erectile Tissue
Function of the Corporus Spongiosum - answer-;Erectile Tissue
Function of the Penile Urethra - answer-;Carry urine and semen
Function of the Glans Penis - answer-;Stimulation
Function of the Prepuce(foreskin) - answer-;Stimulation
What is Circumcision? - answer-;Circumcision is the surgical removal of the
