The Micturition Reflex01:26

The Micturition Reflex

966
Urination, or micturition involves the coordination of the bladder's detrusor muscle and two sphincters to ensure controlled bladder emptying.
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating...

External Female Genitals01:15

External Female Genitals

11.5K
The vulva encompasses the external structures of the female reproductive system. At the forefront is the monpubis, a cushion of fatty tissue atop the pubic bone. Once puberty sets in, this area typically grows hair. Extending from just behind the mons pubis are the labia majora (labia = 'lips'; majora = 'larger'), which are larger skin fs olds coated with hair. Nestled within are the labia minora (labia = 'lips'; minora = 'smaller'), which are thinner, more...

Anatomy of the Genitourinary System II: Bladder and Urethra

186
The lower urinary system consists of the urinary bladder and urethra, which are essential in storing and expelling urine from the body. Together with the internal and external sphincters, these structures work together to regulate urination effectively.Anatomy of the BladderThe urinary bladder is a muscular, stretchable organ behind the pubic bone and in front of the rectum. In females, the bladder is positioned anterior to the vagina and inferior to the uterus, while in males, it is located...

Imaging Studies VI: Voiding Cystourethrography and Cystography

94
Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

Urethra01:16

Urethra

1.6K
The urethra is a hollowed tubular organ through which urine is expelled from the body. This structure extends from the bladder to the external opening, allowing urine to be released.
The anatomy of the urethra differs between males and females. In females, the urethra is short, measuring about 3–4 cm in length, and opens anterior to the vaginal opening. In males, the urethra is longer and passes through the penis, serving dual purposes: expelling urine and ejaculating semen. The male...

Male Sexual Response: Erection & Ejaculation01:17

Male Sexual Response: Erection & Ejaculation

4.3K
Sexual stimulation can take various forms, such as physical touch and visual or auditory cues. When this happens, the parasympathetic reflex in the sacral portion of the spinal cord is activated. This reflex stimulates the release of nitric oxide (NO), which then dilates the arterioles in the penis, increasing blood flow to the erectile tissues - the corpora cavernosa and corpus spongiosum.
The blood filling the erectile tissues compresses the veins, which helps to prevent blood from leaving...

Summary

Female squirting involves the expulsion of fluid from the urethra, primarily composed of urine. This study confirmed urine as the main component, with some fluid potentially originating from Skene's glands.

Area of Science:

  • Female sexual response and anatomy
  • Urology
  • Gynecology

Background:

  • Squirting, the expulsion of fluid from the female urethra during sexual arousal, is a phenomenon not fully understood.
  • The exact physiological mechanism and composition of the expelled fluid remain subjects of scientific inquiry.

Purpose of the Study:

  • To elucidate the mechanism of female squirting.
  • To determine the origin and composition of fluid expelled during squirting.

Main Methods:

  • Five women capable of squirting participated in the study.
  • A bladder catheter was used to empty the bladder, followed by injection of a blue-dyed saline mixture.
  • Sexual stimulation was applied, and expelled fluid was collected, videotaped, and analyzed for prostate-specific antigen (PSA) and glucose levels.

Main Results:

  • The expelled fluid was blue in all participants, confirming the bladder as the source.
  • Prostate-specific antigen (PSA) was detected in the fluid of four out of five participants.
  • The women experienced squirting through manual or penetrative sexual stimulation.

Conclusions:

  • The primary component of fluid expelled during squirting is urine.
  • Fluid from Skene's glands (female prostate) may also contribute to the expelled fluid.
  • This study enhanced the visualization of squirting and provided evidence for its origin from the bladder.
