Does Holding Back Ejaculation Cause Penile Blockage and Reduced Urine Flow? - Urology

Private inquiry?


When I masturbate, I worry about getting semen on my underwear, so I hold my foreskin to prevent ejaculation.
I would like to know if ejaculating too much semen could cause it to remain in the penis, leading to blockage and a decrease in urine flow?

Hello: It will not flow back into the penis, nor will it cause obstruction of the penis; it should be referred to as the urethra rather than the penis, and it will not significantly affect urine volume.
Wishing you peace and happiness.

Holding back ejaculation, or attempting to prevent semen from exiting the body during masturbation, is a practice that can lead to various physiological effects, but it is unlikely to cause penile blockage or significantly reduce urine flow in a healthy individual.
When ejaculation is inhibited, the semen produced by the seminal vesicles and prostate gland can accumulate in the reproductive tract. However, this accumulation does not typically lead to a blockage in the penis itself. The male reproductive system is designed to handle the production and expulsion of semen efficiently. If ejaculation is consistently withheld, it may lead to discomfort or a feeling of fullness in the testes or prostate, but it does not create a physical blockage in the penis.

Regarding urine flow, the urethra serves as the common passage for both urine and semen. In normal circumstances, the body has mechanisms to ensure that urine flow is not significantly obstructed by the presence of semen. The prostate gland and the muscles surrounding the urethra play critical roles in regulating the flow of urine and semen. When ejaculation occurs, the muscles contract to expel semen, and this process is separate from the mechanisms that control urine flow.

However, if a person frequently engages in practices that involve excessive pressure on the penis or urethra, such as squeezing the foreskin or applying significant force to prevent ejaculation, it could potentially lead to temporary discomfort or a sensation of reduced urine flow. This is not due to a blockage but rather a result of muscle tension or irritation in the area.
In some cases, if there is a significant buildup of semen due to prolonged abstinence from ejaculation, it may lead to a condition known as "seminal vesiculitis," which is inflammation of the seminal vesicles. This condition can cause discomfort and may affect urinary symptoms, but it is generally not a direct cause of a blockage in the penis.

If you are experiencing persistent issues with urination or discomfort in the genital area, it is advisable to consult a healthcare professional. They can provide a thorough evaluation and determine if there are any underlying conditions that need to be addressed.
In summary, while holding back ejaculation may lead to temporary sensations of fullness or discomfort, it does not typically cause penile blockage or significantly reduce urine flow. Maintaining a healthy sexual practice and being mindful of any discomfort can help ensure that your reproductive and urinary systems function optimally. If you have concerns about your sexual health or urinary function, seeking medical advice is always a prudent step.

Question: If incomplete ejaculation occurs, can it sometimes lead to ureteral obstruction, causing difficulty in urination, or is it due to bodily weakness resulting in weaker sperm, with some remaining in the urethra?


Dr. Li Xinyi reply Urology
Hello: The male reproductive and urinary tracts are only connected at the lower urinary tract, and they generally do not influence each other. Sperm does not cause urethral obstruction.

Does Holding Back During Masturbation Affect Sperm Retention?
