Menstrual cups are a popular, sustainable option for managing a period, but they often raise questions about daily routines. New users frequently ask if the cup needs to be removed every time they use the toilet. The answer is that you can urinate without needing to take out the menstrual cup. Understanding the basic anatomy of the pelvis explains why this is possible.
The Direct Answer: Anatomical Separation
You can easily urinate with a menstrual cup inserted because the cup and the urinary tract are anatomically separate systems with distinct exit points. The female pelvic region features three separate openings: the urethra, the vagina, and the anus. Urine exits the body through the urethra, a small opening located just above the vaginal opening.
The menstrual cup sits securely inside the vaginal canal, a muscular tube that extends inward and is a completely different structure from the urethra. Since the cup only collects menstrual flow from the vagina, it does not obstruct the urethra or interfere with urine flow. This structural arrangement is comparable to two adjacent, independent pipes, where something placed in one does not block the flow through the other.
Practical Considerations During Urination
While the cup does not block the urethra, some users may notice a slight change in the urination experience. The vagina, urethra, and bladder are located in close proximity within the pelvis. If a menstrual cup is firm, large, or positioned too low, it may exert subtle pressure on the bladder or the urethra.
This pressure might manifest as a reduced or slower urine flow, or create a sensation of needing to urinate more frequently. If discomfort or difficulty emptying the bladder is felt, gently adjusting the cup’s position or trying a softer cup material can often resolve the issue. It is not necessary to remove the cup simply to pass urine, and standard hygiene practices, such as wiping front to back, should be maintained.
Comparison to Bowel Movements
The experience of having a bowel movement while wearing a menstrual cup differs from urination due to the anatomy and muscle engagement involved. The rectum, which leads to the anus, is located directly behind the vaginal canal. When bearing down or straining during a bowel movement, the pelvic floor muscles contract, which can put pressure on the adjacent vaginal wall.
This internal pressure can sometimes cause the menstrual cup to shift lower in the vaginal canal or partially break its suction seal. For some people, the cup may feel like it is being pushed out, especially if it is a soft cup. If the cup consistently shifts or causes discomfort during defecation, a user might choose to remove and reinsert it. However, this is a matter of personal preference and not a requirement for safe use.
