Flies react to sex, not just in the semen
"The flies react to sex, not just in the semen"

"Flughonor react to the actual feeling of sex, not just the sperm, according to research. In this way she can quickly determine whether she should continue to mate with other males or not."

"Of fruit flies is the so-called spermaeffekten a well-known fact. That is to say that there's a specific substance in the male's ejaculate which make females uninterested in sex after mating. The effect can remain for up to a week and in this way increases the chances that the particular male's sperm, and not someone else's, may fertilize the female's eggs."

"But now scientists at the Howard Hughes Medical Institute in the US discovered that even down in itself, that is to say, the actual feeling of the sex, can have the same effect on the female. The researchers, who publish their results in the journal Neuron, call it kopuleringseffekten. An effect that seems faster, but not sit in as long as spermaeffekten."

"– It can be a quick way for the female to decide if she should continue to try to mate or if she can take it easy, " says one of the researchers behind the article, Ulrike Heberlein, to the journal."

"the Phenomenon was discovered when researchers mated the flies in which the males were manipulated so that they lacked the ability to ejaculate, which is why this specific substance is not transferred to the female."

"Although it was, therefore, the females want to have continued sex with other flughanar. It turned out that there are a few specific neurons in the female's abdomen that transmits the signals, provided that the male body fits like a glove. For it is only then that the female's interest waning. When the researchers blocked the effect of these nerve cells, continued the females to mate that nothing had happened."
