The word prostate comes from the word "prostates", which is derived from a Greek word. Its meaning is standing in front, guard and protector. The size of a normal prostate in a healthy male is as a large walnut. The weight of the prostate is between 10 and 20 grams. It is located at the base of the urinary bladder and it also surrounds the urinary tract.
Sperm (male germ cell) is produced in testicles. Vas deferens (the seminal tract) transports sperms from testicle to penis. Vasectomy is a small procedure in which vas deferens is excised. After this operation, no change occurs in the appearance of the fluid discharged during intercourse; however, pregnancy does not occur because there is no sperm cell in the fluid.
Erectile dysfunction is the inability to commence and/or maintain an erection required for sexual intercourse. Since individuals with this disorder often think of it as a normal condition resulting from age or an irrecoverable condition they do not feel the need to get medical support and help. In fact, this is a treatable disorder. Erectile dysfunction is a very common condition. Two out of three males over 40 at least at some point experience problems developing or maintaining an erection.
