Once a month ovulating women of childbearing age, the egg is released from the ovary to the fallopian falopia to be fertilized. When the volatile hormones and chemicals in the brain change. Ovulation proved affect the brain, body and behavior in a surprising way.
"Hormones affect the whole body, not just the reproductive organs, mind, behavior and even appearance changed during the process of ovulation," said Carol Gnatuk, MD, assistant professor of obstetrics and gynecology at Penn State Milton S. Hershey Medical Center.
Here are the symptoms that indicate a woman is in the fertile period:
The face looks slightly redder
A study published in the journal PLoS One found the woman's face became slightly reddish in the days leading up to and during ovulation.
This makes sense, said Dr. Gnatuk, because hormones affect blood flow throughout the body. "Higher estrogen levels during ovulation can cause blood vessels to dilate. When the dilated vessels near the skin, so women look more radiant skin," he explained.
The study researchers said the effects of this redness may be seen by men and may solve the mystery of how and why men see women who are ovulating more attractive sexually. But changes in facial redness can only be detected by a highly sensitive camera, instead of the naked eye.
Feel more cheerful
It makes sense that a woman's libido rises during the fertile period. But women who do not ovulate consciously think more about sex. According to a study in 2010 in the Journal of Consumer Research, during ovulation women unconsciously buy sexier clothes and wear.
Research also found that women dream more about sex in the first half of the menstrual cycle when the body toward ovulation compared to the second half when the body prepares to enter the menstrual period. One small study found that women may have an erotic interpretation of abstract art more when they are ovulating than in the recent past menstrual cycles.
"Libido is not entirely driven by hormones, if yes, the sex will only be when and not where or with whom," said Dr. Gnatuk. "But certainly, estrogen and testosterone levels are higher during ovulation may increase the desire of a woman," he added.
Interested in the kind of guy
Women are not only being "mood" during ovulation but also more interested in the kind of man than others. The study found women tend to choose and pay attention to attractive men during the fertile period, especially if the couple that there is currently less man has facial features such as the shape of the jaw box.
"When he was in the fertile period, we look for characteristics that are related to good health. That includes healthy testosterone levels that enable men to produce and protect their offspring," he said.
Another study from 2011 in the journal Psychological Science found women are better assess the sexual orientation of men when they are ovulating. Maybe seen from an evolutionary perspective, it's no use chasing a man who was not interested.
Senses become more sensitive
Fertile women tend to be more able to detect odors and pheromones male hormones than those who drink oral contraceptives ovulation suppression. According to a small study from 2013 in the journal Hormone and Behavior. Another study from the same year found that women have a better sense of smell is common during ovulation.
In addition, women are also better able to detect dangers that threaten self and offspring. An early study in 2012 at Kyoto University found women in the luteal phase of the cycle (which begins with ovulation) are better able to find a snake hidden in the picture with flowers.
Avoid male relatives
According to the UCLA study in 2010, women avoid talking to her father on the phone during the most fertile period of the month. Researchers speculate historically, in the interests of women and their offspring, they better avoid male relatives of the possibility of incest.
