Conditions That Influence Flaccid Penis Size
Posted by PRS on March 30th, 2007
Anyone who practices natural penis enlargement knows that "measuring day" is an exciting time. It's on this day that the results of all your effort are calculated and your gains are measured. Accurately measuring the penis, however, especially it's flaccid (soft) state is not as simple as most would assume. The penis is like no other part of the male body and it's size changes from one moment to the next. Conditions such as emotional state, temperature and blood flow are all important factors in determining the size of the flaccid penis.

Undertanding the Sperm Cell
Posted by PRS on December 21st, 2006
Pretty much everyone who has had sexual education class in grade school can tell you that to make a baby, a sperm cell and egg cell must first come together. During sexual intercourse, a man's sperm is released into a woman's cervix and swims to the fallopian tube. Out of the millions of sperm cells, only one penetrates the egg in a process known as fertilization. At that point, life begins. But what is the sperm's role in this process?

Semen Composition
Posted by PRS on May 4th, 2006
Semen is the fluid secreted by the male sexual glands that contains spermatozoa, or sperm cells. This fluid is discharged from the body through the process known as ejaculation and used to fertilize the female ova (egg).
Human semen is mainly composed of seminal plasma, the fluid secreted by the accessory male reproductive organs (the seminal vesicles and the prostate gland). Semen's texture and cohesion comes from a small amount of viscous mucus that is contributed by the bulbourethral glands.
