myth. urinary bladders of both sexes have same capacity of storage.
This gives the physiological capacity of the adult male and female as 500 ml, and notes that there is probably no inherent difference between male and female. The habit of urination has a direct bearing on the size of the bladder.
Gender was shown to have a significant impact on both the position and shape of the bladder: the female bladder was positioned more caudally and was less compact in the transverse plane than the male bladder. Furthermore, there was significant cranial-dorsal movement of the bladder during filling.
So, here's the kicker: Small bladders don't exist. When someone says they have a small bladder, their tank is probably the same size as everyone else's. The difference is actually in the sensitivity of their bladder.
Men and women have lower urinary tracts that carry out the same job of storing and releasing urine from the body. However, parts of the male and female lower urinary tracts are structured differently. The bladder is the same, but the urethra is not.
The truth is, there are a number of reasons why men might opt to sit down—and research suggests that more guys do it than might be expected. Data—admittedly, data from 2007, but hey, this isn't studied too often—shows that 42 percent of married men sit down to urinate, presumably due to spousal pressure.
Prolapse is the bulging or dropping of the rectum or bladder. It is more common in females but can occur in males as well.
Urinary bladder and urethra
The urinary bladder can store up to 500 ml of urine in women and 700 ml in men. People already feel the need to urinate (pee) when their bladder has between 200 and 350 ml of urine in it.
The human bladder can hold a fair amount of liquid: About 2.3 cups for the average woman and up to 2.9 cups for the average man, according to Germany's Institute for Quality and Efficiency in Health Care (opens in new tab). That's about 17 ounces (500 milliliters) for women and 23 ounces (700 ml) for men.
Summary: University of Pittsburgh researchers compared data taken from women between the ages of 22 and 90 and found that although the bladder does deteriorate as women age, it may not shrink, as has been commonly believed.
A full bladder can actually push some arousing and sensitive areas like clitoris and its branches. Most importantly, the G- spot is around the entrance of the bladder which contributes to the increased sexual experience if your bladder is full.
The detrusor is thicker in men than women, as greater voiding pressure is needed to empty the bladder through the longer urethra of males [7]. The ratio between SM and connective tissue does not differ between women and men of any age [8].
Levels of urinary metabolites, including UDP-glucuronic acid, α-ketoglutarate, and 2-hydroxyglutaric acid, were found to be higher or lower in females than in males (Fig. 3). We further hypothesized the biology associated with sex-specific metabolites detected in urine samples is linked with sex hormones.

For healthy men, no difference is found in any of the urodynamic parameters. In patients with LUTS, the sitting position is linked with an improved urodynamic profile.
Expert answer. Thanks for your question. In general, most adults urinate about once every two to four hours when awake, for a total of about six to eight times in a 24-hour period.
Bladder. This triangle-shaped, hollow organ is located in the lower abdomen. It is held in place by ligaments that are attached to other organs and the pelvic bones. The bladder's walls relax and expand to store urine, and contract and flatten to empty urine through the urethra.
A healthy bladder can hold about 2 cups of urine before it's considered full. It takes your body 9 to 10 hours to produce 2 cups of urine. That's about as long as you can wait and still be in the safe zone without the possibility of damaging your organs.
Normal functional bladder capacity in adults ranges from approximately 300 to 400 ml (58,59).
Urinary incontinence in men is often related to prostate problems. As men age, the prostate gland grows larger, squeezing the urethra and pushing the neck of the bladder out of position. These changes can lead to incontinence.
Functionally, when you stand up, there is a little bit of urine left in the urethra, which empties as you stand and gravity takes over. You weren't able to fully relax your pelvic floor muscles and completely void. (If you have pinched a straw with water in it and let go, a similar thing is happening).
The elastic tissue becomes stiffer and the bladder becomes less stretchy. The bladder cannot hold as much urine as before. The bladder muscles weaken. The urethra can become partially or totally blocked.
When you do pass stool however, the relaxation of the stronger anal sphincter also decreases tension in the weaker urinary sphincter, allowing urine to pass at the same time. But this isn't always the case – it is possible, but difficult, to do one without doing the other.
“A lot of guys sit to pee if they can't fully evacuate their bladder. When you sit down, you can use your abdominal muscles more, and you get your last few squirts out and feel like you've emptied better.” In fact, this is something that helps Mills diagnose patients who might have problems peeing.
Sitting allows the pelvic floor muscles to relax, which reduces pressure on the urethra (the urine tube that carries pee to the outside world) and allows smooth voiding.
