Prostate
The prostate is a gland that is part of male mammalian sex organs. Its main function is to secrete and store a clear, slightly basic fluid that is part of semen. The prostate differs considerably between species anatomically, chemically and physiologically. A healthy human prostate is slightly larger than a walnut. It surrounds the urethra just below the urinary bladder. It is located in front of the rectum and part of it can be felt during a rectal exam.

The male urethra has two functions: to carry urine from the bladder during urination and to carry semen during ejaculation. Within the prostate, the urethra coming from the bladder merges with the two ejaculatory ducts.

Semen is composed of sperm and seminal fluid; about 10-30% of the seminal fluid is produced by the prostate gland, the rest is produced by the two seminal vesicles.

To work properly, the prostate needs male hormones (androgens). Male hormones are responsible for male sex characteristics. The main male hormone is testosterone, which is produced mainly by the testicles. Some male hormones are produced in small amounts by the adrenal glands.

Rob Kells succumbs to prostate/marrow/bone cancer
Rob Kells succumbs to prostate/marrow/bone cancer http://willswing.com Rob Kells succumbed to his illness on August 9th in Austria where he had gone with Trish, his wife, for treatment. Rob had made known his condition for the last two years and made strenuous effort to fight against the cancer, see here: http://willswing.com/flystrong.asp. But these types of cancers are fast growing and really tear down your immune system. And, of course, cancer treatments also wreck havoc on your immune system. Belinda remembers Rob as a person who made every pilot feel important. She remembers how encouraging he was to her when she was flying. I remember Rob as a great ambassador for the sport and for his company. He was a great supporter of the Oz Report and of me, as well as many other pilots. In the last few years he worked hard to develop a group of pilots who were proud to fly the top of the line Wills Wing glider in competition and do very well. For example, Dustin Martin won the first two US competitions this year on a Wills Wing T2 144. Rob, Steve, Mike and Linda formed a great partnership at Wills Wing and I'm sure that they feel the loss of their friend and president deeply. I hope that all pilots around the world can express their sympathies to Rob's friends and family. Discuss Rob Kells at the Oz Report forum link»
