Summary
Female ejaculation is a physiological phenomenon in women, not linked to detrusor overactivity or incontinence. Further investigation is unnecessary for women experiencing female ejaculation without other urinary symptoms.
Area of Science:
- Urology
- Female Sexual Health
- Lower Urinary Tract Symptoms
Background:
- Surveys indicate 40-54% of women report fluid expulsion during orgasm.
- This fluid is sometimes identified as female ejaculate, distinct from coital incontinence.
Purpose of the Study:
- To determine if female ejaculation is associated with detrusor overactivity.
- To assess if female ejaculation correlates with bothersome lower urinary tract symptoms (LUTS) like coital incontinence.
Main Methods:
- Recruited six women reporting female ejaculation and six controls.
- Utilized 3-day bladder diaries, Urgency Perception Scale (UPS), and Incontinence Impact Questionnaire (IIQ).
- Conducted provocative ambulatory urodynamics to detect detrusor overactivity.
Main Results:
- No detrusor overactivity was observed in any participant, regardless of female ejaculation status.
- Bladder diary and questionnaire results were within normal ranges for all women.
Conclusions:
- Female ejaculation may be a normal physiological event without associated urinary dysfunction.
- Women experiencing female ejaculation without other LUTS do not require urological investigation and can be reassured.

01:26The Micturition Reflex
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 urine...

01:19Anatomy of the Genitourinary System II: Bladder and Urethra
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...
01:23Urinary Bladder
The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

01:19Urodynamic Studies: Uroflowmetry
Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...
01:16Urethra
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 urethra is...

01:28Microbiota of the Urogenital Tract
The human urogenital system, once thought to be sterile in healthy individuals, is now recognized as a complex microbial habitat. Advancements in molecular sequencing techniques have revealed that even in healthy adults, the kidneys and bladder harbor microbial populations similar to those found in the distal urethra, albeit in much lower abundance. These resident microorganisms, while generally innocuous, can become opportunistic pathogens under conditions that alter the urogenital...
