Urethra Capacity Test

Pinch the urethra spout shut and slowly fill with urine. Stop when you've reached your capacity.

✅ Drain the urine into a jar, this is your internal capacity volume.

Generate a load of ejaculate and release into a second container.

• If the ejaculate volume is less, go with the No Pocket 'extra-grip' version for longer hold.
• If the ejaculate volume is more, go with the Pocket Tip version for extra storage and comfort.

IF your capacity and ejaculate volume is average, Jiftip will work for you.

Relax—your body's built for this.

Dr. Kenji Tanaka, urology specialist, confirms: "the male urethra can comfortably contain 4 to 6 ml, while the average male ejaculation volume is only 2 to 4 ml."

Pocket Tip: Built-in pocket expands to provide additional storage space and greater comfort.

No Pocket: Extra secure grip that holds everything inside, more suitable for average capacity (2-4 ml).
