Sexual health – Scientists may never fully understand male sexual behavior, but a new study sheds light on at least one biological aspect of ejaculation. Researchers have a new cell information that connects the spinal cord region identified that controls male ejaculation the pleasure of the brains reward center.

Previous studies by the same group identified cells in the spinal cord that ejaculation should be sent signals to the brains, but not involved in other aspects of sexual behavior.
When the researchers group slain in a cell group of male rats addressed the rats not fail to notice their sexual behavior remained unchanged. But the rats no longer ejaculates, which confirms that these cells control ejaculation.
Detected after ejaculation-related part of the spinal cord, researchers began looking at the ways that signals between the brains of male genitalia and pass.
Their latest research shows that the center of the spinal ejaculation ejaculation also sends signals to the motivation and reward center of the brains, suggesting that male sexual behavior can affect.
In addition, the laboratory tests on rats showed that their brains release of various chemicals in various stages of sexual behavior.
But the researchers point out that rats differ from humans in many ways when it comes to sexual behavior. For example, a male rat respect to 10 ejaculations over a period of two hours (with intervals of five minutes) before they lose interest in a receptive female.
No matter, says Coolen, most previous studies on sexual behavior of rats were subsequently confirmed by the man. And by learning more about the biological processes behind ejaculation researchers may eventually understand that sexual behavior and the development of new ways to treat sexual dysfunction.
