Can you tell a baby's sex just by looking at their buttocks? The doctor has spoken!

My aunt said, "Look at your big butt, you're sure to give birth to a chubby boy!"

I checked the almanac today and was surprised to find that today's fortune indicates it's not a good day for travel, but a good day for writing and copying. So I quickly grabbed a pen and started writing something.

Today's topic will begin with a painting. What painting?

This is the painting "Lady Guo's Spring Outing".

The painting depicts Lady Guo, the third sister of Yang Guifei, a favorite concubine of Emperor Xuanzong of Tang, and her retinue on a grand outing. The painting shows the beautiful woman already dressed in a low-cut top, perhaps reflecting the open-mindedness of the Tang Dynasty. Ancient Chinese people traditionally considered large hips in women to be a sign of fertility and the potential for many sons.

Therefore, in the paintings, the women try to wrap their breasts with cotton cloth to make them appear smaller, and they deliberately walk with their toes pointing inwards to make their hips appear larger. As for the hips, they were believed to be closely related to pregnancy and childbirth. For a long time, due to various feudal ethics, women with larger breasts or hips were considered to be fertile or destined to have sons.

appearance

Is a large bottom a sign of fertility and the ability to father many sons?

Is this statement reasonable?

In metaphysics, there are concepts of physical appearance, flesh appearance, and bone appearance. The term "physical appearance" in "Dream of the Red Chamber" refers to Jia Baoyu.

West River Moon – Two Poems Mocking Jia Baoyu

He seeks sorrow and hatred for no reason, sometimes appearing foolish and mad. Though he may be born with a handsome appearance, his inner self is nothing but weeds.

Here, "skin" refers to physical appearance, or simply "face." Especially in a society where looks and family connections matter, it's practically impossible to survive without good looks.

Top-tier physical appearance:

In ancient times, there were geese descending on the sandbar, the moon hiding its face and flowers blushing with shame, Yang Guifei getting drunk, and Wang Zhaojun leaving the border.

Today, we have Zhang Min turning her head, Zhu Yin, Joey Wong changing clothes, and Brigitte Lin holding a cup.

Regarding physical appearance, the so-called "internet celebrity face" is popular these days. Although it's often ridiculed, the features of these faces are actually quite refined: double eyelids, a high nose bridge, full lips, flawless white skin, and thick, long hair. With the help of beauty filters, they look flawlessly beautiful in photos and live streams, but they lack authenticity and appear slightly stiff, like looking at a doll in a shop window (as a straight male OB-GYN, this is my aesthetic opinion...). However, whether someone is good-looking or not has little to do with whether they can have children, or even have a healthy baby boy!

flesh appearance

A poem says, "Mountains are the remnants of ancient bones, monks without flesh are truly cultured." Here, "flesh" refers to an ordinary appearance.

However, in obstetrics and gynecology, "flesh appearance" refers to body fat percentage. Body fat percentage refers to the proportion of fat weight in the total body weight, also known as body fat percentage, and it reflects the amount of fat in the body. The normal body fat percentage for adults is 15%~18% for men and 25%~28% for women.

Body fat percentage should be maintained within the normal range. Excessively high body fat percentage can easily lead to gestational bleeding, gestational diabetes, gestational hypertension, and other metabolic disorders. It also increases the likelihood of cesarean section and fat liquefaction at the incision site. Conversely, excessively low body fat percentage can easily lead to reproductive endocrine disorders, and in severe cases, amenorrhea or even infertility.

Science is about data. BMI is an abbreviation for Body Mass Index.

Ladies, the denominator of your Body Mass Index (BMI) is generally constant. What you need to do is make the numerator smaller (of course, if you can make the denominator larger, that's another story), and your BMI will naturally decrease, and your health will follow.

Bone structure

As the saying goes, "You can know a person's face but not their heart; you can draw a tiger's skin but not its bones." This is like the steel frame of a house, which supports the entire structure. The stronger the structure, the more functions the house can support.

If this is true of things, how much more so of people?

Bone structure refers to the structure of the skeleton. While skin appearance can be modified with scalpels and cosmetics, bones are much more difficult to alter. Even if one could work on the jawline or, for the most daring, remove ribs, one would likely have considerable reservations before attempting to work on one's own skull!

Of course, in our obstetrics and gynecology department, the importance of bone structure (especially the pelvis) lies not only in its aesthetic appearance, but also in its practicality.

Can you tell a boy or a girl just by looking at a butt?

I've heard that a department head can basically determine the sex of a baby just by looking at the pregnant woman's gait and the size of her hips. I haven't verified this myself. It's absolutely amazing!!!

Judging whether a woman is likely to have a son mainly involves observing the size of her buttocks. Scientifically speaking, this is called observing the waist-to-hip ratio. I believe this is merely an empirical hypothesis derived from long-term observation of many pregnant women. This statement is a flawed one, reversing cause and effect and generalizing from limited information. The underlying theory supporting this view is that in the later stages of pregnancy, a boy's head develops larger, thus stretching the pelvic ligaments more.

However, from a genetic perspective, whether a child is a boy or a girl is determined by the male's genes. What business is it of the pregnant woman's?

Can you tell how many children someone can have just by looking at their butt?

First, whether or not one can conceive depends on factors such as whether there are obstacles to the union of sperm and egg between the man and woman, and whether implantation is successful.

What does this have to do with buttocks?

Having large hips could be due to excess fat in the buttocks, not necessarily a large pelvis. Even with a large pelvis, if the fetus is too large, a cesarean section may be necessary. Therefore, the ease of delivery and the fetus's ability to be delivered vaginally depend on a combination of factors, including the strength of labor, the birth canal, the fetus, and psychological factors.

In conclusion, the only advantage of having a big butt is a stable base, making walking safer. (So, next time your aunts and uncles tell you, "You have a big butt, you're sure to have a son," just chuckle!)
