Male squirting: Analysis of one case using color Doppler ultrasonography

Abstract

Introduction There is no scientific evidence for the mechanism of male squirting, although the term is common in mass media. Here, we describe the first recording of male squirting using color Doppler ultrasonography. Case presentation We recruited a 25‐year‐old male volunteer who was able to have male squirting. A transrectal ultrasound probe was inserted into the rectum and male squirting was observed following normal ejaculation. With penis stimulation for a further 20 s after ejaculation, translucent misty fluids with a creatine level similar to that of urine came from the extraurethral orifice for about 60 s. Color Doppler ultrasonography recorded strong contraction of the prostate and pelvic striated muscles just before male squirting, and then the stream went from the urinary bladder through the prostatic urethra. Conclusion In male squirting, urine in the bladder gushes out from the external urethral orifice due to strong contraction of the prostate and pelvic striated muscles.

Enhanced visualization of female squirting

“…The squirting phenomenon in males involves the release of urine after ejaculation. 10 If the same is true for females, the first fluid to be released during squirting will have a high concentration of PSA. If the fluid is collected before the squirting phenomenon occurs, it is possible to obtain the first portion of liquid, which may contain prostatic fluid.…”

“…It is not known if the ejaculatory fluid is emitted during the squirting phenomenon or if the ejaculatory fluid is released first, followed by urine. The squirting phenomenon in males involves the release of urine after ejaculation 10 . If the same is true for females, the first fluid to be released during squirting will have a high concentration of PSA.…”
