To treat the erectile dysfunction, it is important to know how the erection develops. Penis is a male genital organ that has its peculiar structure and anatomy.
The structure of penis is the following:
• Two cavities continuing through the length of penis. So called cavernous bodies. They have the plexus of blood vessels and arteries inside.
• Urethra – the special channel for urine and sperm. It goes inside the cavernous bodies.
• Erective tissues placed in the cavernous bodies. They connect with main arteries.
• Penis stem – the main and the longest part of penis.
• Balanus, situated at the end of stem.
• The opening on the balanus, through which the urine and sperm discharge.
How does the erection form? 
Erection is merely the result of hard work in the body that involves the interaction of several systems. Firstly, there is an impulse from the brain that causes the start of the chemical reaction in the body. This is the response to the stimulation. As the result the blood vessels in penis relax and the blood starts to flow to tissues and actively fills the vessels inside penis that continue through the length of penis. Then the blood flows to the cavernous bodies and remains there. This maintains the erection during the long time.
After the drive reduces the blood starts flowing back the same way. When the urinary pipe opens, the pressure reduces and the blood starts to flow back. Erection weakens, bring penis to normal state.

When does the ejaculation take place?
Ejaculation is the emission of seminal fluid in the end of sexual intercourse that is during the orgasm. This happens when a man reaches the highest point of drive. This is a kind of culmination not only in sex, but also in the work of various systems of the body. During the sexual stimulation the nervous terminals in penis respond and send the corresponding chemical signals to cerebrospinal axis. They gradually grow, and the brain responds to the intense influence. It sends responsive signals that lead to the drive and ejaculation.
The ejaculation process comprises two stages. Firstly, the arctation of spermiduct takes place, sending sperm from testes to urethra. Before that it is in a special pipe that connects testes and urethra. Then the penis muscles start contracting rapidly, pushing the sperm with the high speed after it starts going up through the pipe.
The strength and the intensity of emission may vary depending on different situations. Sometimes it is not even an emission, but an “outpouring” of sperm. It is the normal occurrence that may depend on the intensity of affecting and drive.
