Have you ever heard someone say, “Women have one more rib than men”? It’s a common myth that has been circulating for centuries, and it’s still a topic of debate. But is there any truth to it? Do women really have an extra rib? In this blog post, we’ll break down this age-old belief, dig into the science, and give you the facts. So, let’s clear up this confusion once and for all!
The Myth: Women Have an Extra Rib
This myth seems to have originated from the biblical story of Adam and Eve. According to the story, God created Eve from one of Adam’s ribs. Over time, some people took this to mean that women must have one extra rib compared to men. But, as with most myths, there’s more to the story than just that.
The Truth: No, Women Do Not Have an Extra Rib

Here’s the simple truth: Both men and women typically have the same number of ribs. Humans have 12 pairs of ribs, making a total of 24 ribs. This applies to both men and women. So, despite the myth, there’s no evidence to support the idea that women have an extra rib.
But why does this myth still persist? Let’s dive deeper into the reasons behind this confusion.
Why Do People Believe This Myth?
There are a few reasons why people might still think that women have more ribs than men:
- The Bible Story: As mentioned earlier, the story of Eve being created from Adam’s rib has been passed down through generations. Over time, it’s likely that this story became mixed with a misunderstanding about anatomy.
- Human Anatomy Variations: While it’s true that most people have 12 pairs of ribs, there are rare cases where someone may have an extra rib or fewer ribs. These variations are called “rib anomalies,” but they affect both men and women. In some cases, a person may have a 13th rib, but this is extremely rare and not tied to gender.
- Confusion Over the Terminology: People sometimes confuse the concept of ribs with other parts of the body, such as the collarbone. The collarbone (clavicle) is sometimes mistakenly thought of as a rib, and some people believe women have an extra one of those.
Rib Anomalies: What You Need to Know
Although both men and women typically have 12 pairs of ribs, there are some instances where a person may have more or fewer ribs. These anomalies are extremely rare, but they do occur. Here are some examples:
- Cervical Rib: This is an extra rib that can form above the first rib, near the neck. It’s a rare condition that occurs in less than 1% of the population, and it can happen in both men and women. Most people with a cervical rib don’t experience any symptoms, but in some cases, it can cause pain or discomfort in the neck or arm.
- Lumbar Rib: This is an extra rib that can form on the lower back. It’s even rarer than a cervical rib and is typically found in about 1 in 500 people. Again, this can happen in both men and women.
- Missing Ribs: On the flip side, some people may have fewer than 12 pairs of ribs. This can happen due to genetic conditions or other factors, but it’s also quite rare.
Do Women’s Ribs Differ from Men’s?
The structure of ribs is similar in both men and women, but there are some slight differences. Women tend to have a broader ribcage compared to men, which allows for the space needed to carry a child during pregnancy. However, this difference is not related to the number of ribs but rather to the overall shape and size of the ribcage.
Fun Fact: Rib Removal Surgery
In the past, some people believed that removing a rib could help with cosmetic surgery, particularly for women seeking an hourglass figure. While rib removal surgery has been performed in some extreme cases, it is dangerous and highly discouraged. Removing ribs can lead to severe complications and long-term health risks, so it’s not something that should be done without serious consideration and medical advice.
Conclusion: The Bottom Line
So, do women have an extra rib? The answer is clear: No, they don’t. Men and women both have the same number of ribs—12 pairs, or 24 ribs in total. The myth likely comes from the biblical story of Adam and Eve, combined with misunderstandings about human anatomy. While rare conditions like cervical or lumbar ribs do exist, they affect both men and women equally.
It’s important to rely on scientific facts when it comes to human anatomy, so don’t let myths cloud your understanding of the human body.
FAQs
1. Can women have more ribs than men?
No, men and women both typically have the same number of ribs—12 pairs (24 ribs). Any variations, such as extra or missing ribs, are rare and not determined by gender.
2. What are cervical and lumbar ribs?
Cervical ribs are extra ribs that can form near the neck, and lumbar ribs are extra ribs that form near the lower back. These conditions are rare and affect both men and women.
3. Is rib removal surgery safe?
Rib removal surgery can be dangerous and is not recommended for cosmetic purposes. It can cause complications and long-term health issues, so it should only be done with careful consideration and medical advice.
4. Why do some people believe that women have extra ribs?
The belief likely comes from the biblical story of Adam and Eve, where Eve was said to have been created from Adam’s rib. Over time, this idea became associated with the belief that women have more ribs than men.
5. Can someone have fewer than 12 pairs of ribs?
Yes, in rare cases, some people may have fewer than 12 pairs of ribs due to genetic conditions or other factors. However, this is not common and can affect both men and women.
