While urinating exactly at the same time as ejaculating is uncommon, issues with the muscle that controls the bladder during ejaculation can lead to related conditions, such as semen flowing into the bladder.
The reference provided specifically describes the cause of retrograde ejaculation, a condition where semen travels backward into the bladder instead of exiting the body during climax. This is a related issue involving the same muscular control that prevents urine from mixing with semen or exiting during ejaculation.
According to the reference:
Retrograde ejaculation is caused by a problem with your circular muscle (called the bladder sphincter) that closes to let semen out and keeps urine in your body.
The Role of the Bladder Sphincter
During ejaculation, a critical circular muscle known as the bladder sphincter (specifically, the internal urethral sphincter) plays a vital role:
- It contracts tightly.
- This contraction seals off the bladder opening into the urethra.
- This prevents urine stored in the bladder from entering the urethra and mixing with semen.
- It also directs the semen forward out of the penis.
When this muscle doesn't close properly, it can lead to:
- Semen flowing backward into the bladder (retrograde ejaculation).
- Potentially, though less commonly described than retrograde ejaculation, a malfunction here could theoretically contribute to issues with urine control during ejaculation timing.
Why the Bladder Sphincter Malfunction Happens
Problems with the bladder sphincter causing retrograde ejaculation can stem from various factors:
- Certain surgeries (e.g., prostate surgery, bladder surgery).
- Some medications (e.g., for high blood pressure, prostate enlargement, or mood disorders).
- Nerve damage caused by conditions like diabetes, multiple sclerosis, spinal cord injuries, or certain surgeries.
Symptoms of Retrograde Ejaculation
The primary symptom of retrograde ejaculation is a "dry orgasm", meaning little or no semen is ejaculated from the penis. After ejaculation, the urine passed may appear cloudy because it contains semen.
Understanding the Distinction
While the user's question asks about urinating while ejaculating, the provided reference explains the cause of retrograde ejaculation – where semen goes into the bladder due to a sphincter problem. Both conditions involve the proper functioning of the bladder sphincter during ejaculation, highlighting the muscle's importance in controlling the flow of both urine and semen at different times.
