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

Chapter 6

CONCLUSIONS

The analyses of the post draining fluid that came through the catheter tube into the storage bags raised some interesting questions.  While the results were consistent with the earlier studies done in the 1980ís showing lowered urea and creatinine levels, no signs of any prostatic components such as fructose or glucose were detected.  What is different here is that, because of the catheter, it can be assumed that this fluid came from the bladder.  In the earlier studies where no catheter was used, it was possible that the fluid obtained was a combination of urine from the bladder and fluid expelled from the urethral glands and ducts, mixed together in the urethra.  The earlier lab tests also showed the presence of substances not at the time thought to be present in female urine and present in male prostatic fluid such as fructose.

Therefore, the primary conclusion from the experiment is that, at least for these seven women, all knowledgeable and experienced ejaculators, the fluid expelled through the catheter tube and into the storage bag unquestionably came from their bladders.  Even though their bladders were 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 seem to be that the fluid came from a combination of residual moisture in the walls of the bladder and from post draining kidney output.  While fluid intakes were not monitored, it should be noted that the subjects were given water or soft drinks as requested and that no one was viewed drinking large quantities.

It is important to note the consistency of results that showed a greatly reduced concentration of urea and creatinine in the expelled fluid.  The clear inference is that the expelled fluid is an altered form of urine and that there is a process that goes on during sensual/sexual stimulation and excitement that changes the chemical composition of urine.  There have been some indications, and this is certainly a basis for a follow up study, that the hormone aldosterone and/or elevated blood pressure during sensual/sexual activity might contribute to a lowering of urea and creatinine levels.

While on several occasions there was evidence of milky-white, mucous-like emissions from the urethra outside of the catheter tube which were recorded on video tape, only a small portion of this fluid could be captured for laboratory analysis.  An objective reading of the previous literature, particularly the pathology reports from Zaviacic, indicates the possibility of such an emission from the urethral glands and ducts which would hypothetically be merging with the expelled fluid from the bladder in the urethra.  This seems promising enough to encourage future research employing this studyís methodology of arousing the subjects and then utilizing a Foley catheter to segregate the urethra from the bladder.

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 would indicate, as was suggested by Zaviacic60 and in the Beth Israel study,61  that both may be the case.  In some women, there may be an emission from the urethral glands and ducts which merges in the urethra with fluid from the bladder.  This would explain the seemingly contradictory results from previous studies.  In the cases where prostatic fluid components were discovered, a urethral expulsion may have also taken place.  In other instances, where there was just fluid with lowered amounts of urea and creatinine, an expulsion from the bladder only may have been involved.  In the subjects in the Goldberg, et al, study where there were neither prostatic fluid components nor lowered urea and creatinine levels, the authors may have been correct in their explanation that the subjects may have simply been nervous and may not have been sufficiently aroused to alter urea and creatinine levels.62
