The more attractive the female, the higher the ability to conceive

A study of red jungle chickens, ancestors of domestic chickens proved that the males can adjust sperm speed and effectiveness, depending on how they feel that the object is so attractive to them. how

Published in the Journal of Proceedings of the Royal Society B, this work adds to the evidence that male animals of mixed species (including humans) can increase their ability to conceive if those animals that are attractive to them.

The authors of this project are Dr. Charlie Cornwallis, Oxford University and Dr. Emily O'Connor, Royal Veterinary University, said: "Sexual appeal of the forest chickens is shown in appearance. their genes are genetically related to the number and mass of the eggs they produce. '

They found out that empty greedy chickens had the opportunity to pair with hens, regardless of good or bad. But when the semen is collected, the guys release when they 'love' to analyze the quality, first of all they see that when they have sex with the hens, it is usually the more beautiful the woman is, the faster the speed of sperm ejection The more the volume.

Although it is not known why, scientists have come up with a very interesting hypothesis. They said: 'The roosters change the rate of ejaculation. Each time they have sex, they actively distribute sperm (and even more) through the right or left vas deferens. When their 'love' object is beautiful, they generously donate sperm from both of them '.

Why roosters are not fair to love is a mystery, but scientists hope that in the following study, they will find out how they regulate sperm speed and volume as well as the ratio. how to conceive through this injustice.
