Do Men Have Bigger Bladders? The Shocking Truth in 2023

The Basics of Bladder Function and Capacity

The bladder is a muscular sac located in the lower abdomen that stores and releases urine through the urethra. The size and capacity of the bladder varies depending on the individual, but on average, it can hold about 400-600 mL of urine.

Bladder function is controlled by the nervous system, and signals are sent to the brain to let us know when it’s time to empty our bladder. Gender can also affect bladder function, with men often exhibiting higher urinary flow rates and larger bladder capacities compared to women.

Do Men Have Bigger Bladders?

Studies have shown that men, on average, have larger bladder capacities than women. This is thought to be due to differences in anatomy, with a longer urethra and stronger bladder muscles in men allowing for greater storage capacity.

However, it’s important to note that bladder capacity can vary greatly between individuals, and factors such as age, health conditions, and fluid intake can also impact bladder function and capacity.

Do Men Have Bigger Bladders? Debunking Common Myths and Misconceptions

The commonly held belief that men have larger bladders than women is actually a myth. While it is true that men can typically hold their urine for longer periods of time compared to women, this is not due to a larger bladder size.

Research has shown that the average capacity of the urinary bladder is similar in both men and women, with a range of 400-600 ml. This means that gender does not play a significant role in determining bladder size or capacity.

However, it is important to note that men are more likely to experience symptoms such as frequency, urgency, and nocturia. These symptoms can be caused by a variety of factors including prostate enlargement, bladder infections, or neurological disorders.

In conclusion, while men do not have larger bladders than women, they may experience bladder-related symptoms more commonly. It is important to address any urinary symptoms with a healthcare provider to determine the underlying cause and appropriate treatment.

Factors That Affect Bladder Capacity

Bladder capacity can vary from person to person, and can be affected by a variety of different factors. These factors can impact both bladder function and volume, potentially leading to issues such as frequency, urgency, and nocturia.


As we age, our bladder capacity tends to decrease. This can be due to various factors, such as decreases in muscle and connective tissue tone, as well as changes in the elasticity and compliance of the bladder itself.

Body weight

Body weight can also play a role in bladder capacity, particularly in overweight or obese individuals. In these cases, excess weight can put pressure on the bladder, potentially leading to a decrease in capacity over time.

Diet and hydration

What we eat and drink can also affect our bladder capacity. For example, consuming high amounts of caffeine or alcohol can irritate the bladder, potentially leading to urinary urgency or frequency.

Meanwhile, dehydration can also impact bladder function, leading to reduced capacity and an increased risk of urinary tract infections.

Activity level

A sedentary lifestyle can contribute to a decrease in bladder capacity over time, as immobility can weaken the muscles of the bladder and surrounding pelvic floor. Conversely, high-impact activities such as running can also strain the bladder, potentially leading to reduced volume and function.


Finally, gender can also play a role in bladder capacity. Men typically have larger bladders than women, which can lead to increased capacity for urine storage.

However, this can also make men more prone to issues such as urinary retention or enlarged prostate, which can impact bladder function and increase the risk of urinary tract infections.

Overall, there are many factors that can affect bladder capacity and function. These factors can impact both men and women, and it is important to be aware of potential issues in order to maintain optimal bladder health and function.

The Role of Urinary Incontinence in Bladder Function

While urinary incontinence affects both men and women, men are more likely to experience symptoms of frequency, urgency, and nocturia than urinary urgency incontinence (UUI).

Bladder function can be affected by various factors, including blood flow, pressure, and compliance. Bladder volume is also directly correlated with bladder function, and studies show that men generally have larger bladder capacities than women, with the ability to store up to 700 ml of urine compared to 500 ml in women.

Urinary incontinence can also play a significant role in bladder function, with different types of incontinence affecting the bladder in various ways. Stress incontinence occurs when urine leaks due to exertion on the bladder, such as when coughing, sneezing, or exercising.

Meanwhile, urge incontinence is characterized by a sudden, intense need to urinate that may result in involuntary urine loss. Lastly, overflow incontinence happens when the bladder is unable to empty properly, causing the bladder to become overly full and constantly leaking small amounts of urine.


Men generally have larger bladder volumes than women, which may explain why they experience more frequent urges to urinate and nocturia. However, bladder function is affected by several factors, including blood flow, pressure, and compliance.

Different types of urinary incontinence can also affect bladder function and quality of life in both genders. Future research should focus on prevention, improved diagnostics, and more effective therapies to improve bladder function and overall quality of life.
