Can not be denied if he always liked a woman with sexy body , busty chubby, slim waist and big hips like a spanish guitar. According to the researchers, it is not limited to assessment only merely superficial, because behind all that there is scientific basis for his supporters.

Women with body shape 'plump' assessed more fertile or not exactly difficult to get pregnant and produce offspring. As mentioned in the journal of the Royal Society - the journal Proceedings B, which is done on 119 respondents woman Poland, the researchers say if women with large breasts and hips slim has hormone levels higher than other women.

The researchers weighed and measured the weight of their bodies that include measurement waist, hips, breasts and the area under the breast. They are classified according to four categories, namely: large breasts, waist slender; busty-waist large; chested small-waist slim and busty little waist big.

The researchers also took saliva samples of respondents when they experience menstruation cycle to measure the levels of the hormone 17-b oestradial (E2) and progesterone. High levels of these two types of hormones is an indicator of pregnant women will be easy. From the study mentioned the woman with large breasts and slim waist have the higher hormone levels.

In western societies, a woman with a Barbie doll icon becomes a symbol of beauty but also have the biological basis, said Dr. Grazyna Jasienska, from Harvard University.

Women who have a first category of body shape (large breasts, slender waist) has E2 hormone levels 26 percent higher and rose about 37 percent higher during menstruation than women in three other categories, as well as progesterone levels.

Jasienska who heads the research journal Proceedings B said that if the figure Hourglass body shape (body shape first category) is very popular in the culture of Western society, it also has a scientific basis.

Jasienska also mention non-Western men tend to not really like her Hourglass figure and stout women, which indicates that women have good nutritional value and are considered more attractive.

Martin Tovee from the University of Newcastle who gave birth to the research: 'What makes a person attractive to others? " told the BBC News that the size of a person's body is not the main factor of attraction someone.

Jasienska research results published in the journal of the Royal Society is more likely to compare the size of the chest to the waist that predict hormone levels. Where women become more 'interesting' is only seen from the height, breast size, and waist, obviously Tovee offensive Jasienska research.

Tovee study whether adding a woman's looks 'interesting' is only seen from the image proportions of her body, but the view from the view that the height of the body, breast size, waist or hips of a woman is considered less important.
