Overview
• Anatomy
• Non Urinary Origin
– Female Ejaculate
• G Spot
• Ejaculate Fluid
– Pooled Vaginal Fluid
• Urinary Origin
– Stress Urinary Incontinence
– Detrussor Contraction
The Female Ejaculate
Anatomical Considerations
– Skene’s Gland or ducts analagous to the male
prostate
Non Urinary Origin - History
Grafenberg in ‘50 postulates the existence
of an ejaculate of non urine fluid during
orgasm .
Addiego ’81 finds a higher level of prostatic
acid phospahtase and also coins the Term
“G Spot”
Grafenberg E. The role of the urethra in female orgasm. Int J Sexology 1950;3:145-8
Addiego F, et al Female ejaculation: a case study. J Sex Res 1981;17:1-13
The G Spot - ? Connection with
Female ejaculation
• G spot refers to a small highly sensitive
area on the anterior vaginal wall near
opening
• G spot and ejaculation considered
together because stimulation of spot leads
to a more intense orgasm with resultant
ejaculation
Goldberg DC et al. The G spot and female ejaculation: a review of initial hypotheses. J Sex Marital Ther
1983;9:27-37
G Spot Review
Hines writes on the G spot
Reviews literature from several perspectives
and
concludes “ the G spot will remain a sort of
gynae UFO: much searched for, much
discussed, but unverified by objective
means”

Pooling of vaginal fluid
Coital Incontinence Urinary
Origin
• Mechanisms of urine loss during
sexual activity
– Multi-factorial
but common 23 to 34%
– Leakage with deep penetration and
abdominal pressure 77%
– Leakage with orgasm 74%
– Leakage with clitoral stimulation 50%

Korda and Hilton studies
Detrussor Contraction
Conclusion
• Skene Glands ejaculate
• Pooling of fluid and levator contraction
with orgasm
• Coital / Stress urinary incontinence /
Detrussor Contraction
And the G spot?
Probably most easily found at the end of the
word “shoppinG”
