The Skene's Glands & Female Ejaculation
 

Close up of the anatomy of the female G-Spot & related components

There has been a considerable amount of discussion, both here and in a variety of other places regarding two issues that are somewhat related – the G-Spot, and female ejaculation.  Over the course of the past few months, as I’ve been working to put together the CC web site, I’ve come across a variety of informational tidbits about this subject, and I’ve finally put together something that helps explain what is going on here.

The Clitoris


When most people think of the clitoris (clit), they only think of the little glans that is present and (usually) visible. In reality, the clitoris is a shaft that extends back into the pelvic region of the female. The clit/clitoral shaft derives from the exact same tissue that forms the penis in the male. In the image above, I have represented the clitoral shaft and its nerve bundle (that takes sensations from the clit to the brain) with a pink outline. And, although you cannot tell from this representation, it is actually a forked complex that travels along both sides of the urethral tube, and back into the pelvis. This position shown on the diagram is merely representative, and each person will have a different shape, different location, and different design in how the complex is constructed; not unlike the different shapes and sizes of males penises.

The G-Spot

Notice how the clitoral shaft/nerve comes very close to the internal wall of the vagina. Just as with the male penis, when a female experiences sexual arousal, the clitoral shaft and surrounding tissues become engorged with blood and swell. As this swelling takes place, you may feel it through the vaginal wall. This swollen spot is what you’re taught to feel for as the identifying mark of the “G-Spot.” Since the shaft may be in different locations, or even different sizes, this helps explain why some women have good response to G-spot stimulation and others don’t. If a woman’s clitoral shaft doesn’t come close enough to the vaginal wall, then she may not be able to enjoy G-Spot stimulation to the extent that other women do.

Female in the middle of an orgasmMany women report different “types” of orgasms – some clitorally induced, some vaginally induced, some G-Spot induced, etc.  This stems from the specific nerve bundles that are stimulated when each of those areas is toyed with.  The pundendal nerve serves the clitoris, and the pelvic nerve serves the internal vaginal and cervical areas.  They “feel” different because there are different mechanisms brought to bear at any give point in time to produce them. Stimulation of the just the clit (glans) itself results in a small (relative) orgasm for some women; whereas stimulation and muscular action against the greater concentration of nerves along the vaginal wall inside the body may produce a much stronger orgasm. For many women, their strongest orgasms result from the combined stimulation of both the clit and the G-Spot; this is often referred to as a "blended" orgasm. 

Even in males a similar force is at work; stimulation of just the head of the penis will produce a much weaker orgasm than one derived from stimulation of the entire length of the penis.   There are also a third and fourth set of nerves that may play a role in the female orgasm.  The vagus nerve serves the uterus and cervical areas in women.  The hypogastric nerve serves the same areas in women, and the scrotum in males (it also serves portions of the lower digestive system, which helps explain why males get nauseous when they get kicked or punched in the nuts).


The Skene’s Glands

The Skene’s Glands in women are formed from the same tissue that forms the prostate gland in males. The prostate gland produces seminal fluid – the watery component of semen that provides the substrate that allows sperm to live and thrive until and when ejaculation occurs. In women, the Skene’s Glands produce a fluid that is almost identical to the base components of seminal fluid (according to most chemical analyses).

As you can see in the diagram, the Skene’s Glands have several openings (ducts), both into the urethral tube and immediately adjacent to the urethral opening. It is through these ducts that the fluid produced by the glands is excreted. This is identical to the method through which seminal fluid is introduced into the urethra in the male as semen is ejaculated. The glands and the fluid they produce are not known to serve any useful purpose whatsoever in the female.

Female ejaculation

There has been a lot of debate, even in the medical community about whether women actually “ejaculate” or not. It appears that women can and do often ejaculate the fluid produced by the Skene’s Glands, through the ducts identified on the diagram above. This ejaculation appears to be caused by a combination of muscular contractions along and near the clitoral shaft (the PC muscles), and stimulation of the G-Spot. As you can see, the clitoral shaft passes near the glands, and it is not unrealistic to assume that massaging the G-Spot would force any liquid in those glands out. As with any other organ, different women will have different size glands. Therefore, some women may ejaculate greater amounts of fluid than others, depending on how big her glands are. Most women will ejaculate small amounts of this fluid that is hardly perceptible to anyone close enough to see what is going on. Some porn videos (as well as anecdotal evidence) suggest that some women can ejaculate massive amounts of fluid this way. It is not beyond comprehension that some women may have much larger glands than others, so, at least in theory, this appears to be possible (it has not been disproven).

The fact that the Skene’s Ducts are in and along the urethra would also support an explanation as to why some chemical analyses of the female ejaculate sometimes show it to contain urine or chemicals found in urine. Trace amounts of urine remaining in the urethral tube could be expected to mix in with the fluid as it is ejaculated and, indeed, even chemical analysis of male semen shows trace amounts of urine in it.

Summary

As you can see, there is a complex array of parts and processes at work here. The fact that each person is constructed differently, with varying sizes of one organ or another, makes it difficult to produce a “standardized” version of what takes place. The basic concepts outlined above are fairly well accepted by the medical and sexological communities now, however. Hopefully, this will give you some understanding of what is taking place as you discover your body (or that of your partner.)
