A prostatic cyst is a fluid-filled sac tucked inside or next to the prostate. Most are small and silent, but when they enlarge they squeeze the urethra and nearby nerves, giving quiet but steady clues.

The first hint is a slow-starting stream. You wait a few extra seconds, then the flow is weak and stops and starts like a kinked hose.

Urgency shows up next. You feel a sudden “gotta go” signal, yet only a small amount comes out each time.

Deep pelvic pressure follows. It feels like a small golf ball parked between the legs, worse after sitting or ejaculation.

Ejaculate can change. The fluid may be less, slightly cloudy, or mixed with a few drops of blood at the end.

Some men notice a dull ache during sex or when having a bowel movement, as the cyst is pressed forward.

If the cyst blocks the urethra completely, you can’t empty the bladder and the lower belly swells—an emergency.
