Strange super food

When observing the animal world, the scientific community is startled to find that many females often absorb the sperm of the male after having sex with the purpose of . impregnating.

The war between two different genders in the animal world has revealed a new aspect, after experts discovered that females in some species regularly swallow their partner's sperm after being concerned. system. In this case, sperm becomes an unusual form of food, adding nutrients to the female and her eggs, according to a report published in the journal San Biology Letters. ' If the male product is swallowed instead of being used for fertilization, it seems that they have lost the opportunity to circulate the race. Therefore, the males must find ways to ensure that there is a small amount of 'seeds' transferred to the correct address, or egg,' explains team leader Benjamin Wegener of Monash University. (Australia).

Wegener experts said the absorption of sperm after intercourse was fully recorded in countless species. And people are no exception, but of course this behavior is listed as an unusual action, which is not in the normal cycle of the reproductive process. According to Columbia University Medical School (USA), human sperm contains fructose, ascorbic acid, water (also called vitamin C), citric acid, enzyme enzymes, proteins, zinc and many other substances. Therefore, the experts are not joking when saying that this is a list of essential ingredients of energy drinks used in sports.

The absorption of sperm in the animal world is less than in humans, according to Wegener. These habitual species include dead fly flies, flower fly flies, a species of invertebrate sea creatures called Spadella cephaloptera, a leech species, squid Sepiadarium austrinum . In particular, that behavior appears common in squid species, the main object of the study. Wegener and his colleagues discovered this habit in female ink and tracked the transformation of genetic material into nutrients, blatantly speaking as food. This is also the first time this phenomenon has been observed in a female in the case of external fertilization.

Wegener expert said the case is an important difference compared with insemination, there are still a sufficient number of sperm to conceive.'For an external fertilizer with a short sperm storage time, if the female does not coordinate egg laying in time, the male will lose the chance to fertilize , ' he said. To avoid being deprived of 'hard work' , nature has endowed with ink sperm and genetic material of other animals containing many compounds that stimulate egg production in partners. So far, experts have identified more than 80 sperm proteins that reduce the ability to mate immediately after finishing, encouraging 'she' to lay eggs earlier, stimulating ovulation and affect sperm storage time as well as egg fertilization ability. Meanwhile, children practice to be able to control whether they want to eat sperm or save it for the next generation.

From the above cases, the scientists speculate that it seems that children can choose to eat sperm from partners who are not sexually attractive, and save eggs for athletic men and promises to have a better 'breed', to ensure the healthiest descendants will be born.
