Urethral Expulsions During Sensual Arousal and Bladder Catheterization in Seven Human Females

Gary Schubach, Ed.D.


A major area of continued controversy and debate among sex researchers, gynecologists and sex therapists has been and continues to be the question of the phenomenon known as “female ejaculation.”  The current study was an exploratory research experiment designed to provide information about this issue by catheterizing seven women, who reported that they regularly expelled fluid during sensual and/or sexual arousal.

Evidence from various studies of live subjects, involving in total less than fifty women, has shown, at least in these subjects, that what was being considered was a urethral expulsion.  However, with the total number of women studied being so small, it was impossible to rule out the possibility that some woman somewhere is expelling fluid other than through the urethra.  While the current experiment, based upon a review of previous studies, focused on the nature, composition and source of female urethral expulsions during sensual arousal, this researcher was certainly open to observing, capturing and analyzing any expulsions other than from the urethra.

With catheterization, the bladder could be isolated from the urethra so that it could be reliably determined which fluids came from which area.  The fluids obtained could then be analyzed for their individual composition, having lessened the possibility that they had been mixed in the urethra.

The entire experiment was videotaped with a medical doctor and/or a registered nurse present at all times.  The overall environment was designed to be as comfortable and natural as possible for the women subjects in order to increase the probability that there would be fluid to be collected.

The primary conclusion from the experiment was that almost all the fluid expelled from these seven women unquestionably came from their bladders.  Even though their bladders had been drained, they still expelled from 50 ml to 900 ml of fluid through the tube and into the catheter bag.  The only reasonable conclusion would be that the fluid came from a combination of residual moisture in the walls of the bladder and from post draining kidney output.

There was also a consistency of results that showed a greatly reduced concentration of the two primary components of urine, urea and creatinine, in the expelled fluid.  A review of previous literature leads to an inference that it is possible that the expelled fluid is an altered form of urine and that there may be a chemical process that goes on during sexual stimulation and excitement that changes the composition of urine.

On four occasions the research team saw evidence of milky-white, mucous-like emissions from the urethra outside of the catheter tube.  Although three of those emissions were recorded by the video cameras, the research team was only able to capture a small portion of the fluid for laboratory analysis.  An objective reading of the previous literature indicated the possibility of such an emission from the urethral glands and ducts.

In the past, the assumption has been that female urethral expulsions during sensual and/or sexual activity originated either in the bladder or from the urethral glands and ducts.  The current study, which documented expulsions originating in the bladder, also indicated the possibility that, in some women, there may also be an emission from the urethral glands and ducts.  That possibility seems promising enough to encourage future researchers to employ methodology similar to this study to resolve this age old controversy.
