The epicenter is an area of arousable tissue located in the vaginal wall between the cervix and the bladder, called in anatomic terms as ‘female degenerated prostate’. This nerve rich area is also called as; A-spot, T-spot, second G-spot, deep spot or simply the AFE zone i.e. anterior fornix erogenous zone. It is usually considered as the female counterpart of the male prostate as clitoris is considered as the female counterpart of penis. Stimulation of the epicenter will cause severe contractions of vulval and pelvic organs resulting in orgasm. The epicenter is not known to have post-orgasmic over-sensitivity like the clitoris.

            The existence of the epicenter was first identified by a Malaysian doctor in Kuala Lumpur during the 1990s. There were several reporting by many people related to the epicenter after that and many of them were proven wrong. The location of the epicenter was mispronounced by many reporters. It is actually located at the innermost part of the vagina just above the cervix. The cervix is the lower most part of the uterus protruding into the vaginal cavity from above. Because of its protrusion into the vaginal cavity, it creates a recess behind and around it by the top most portion of the vagina. The anterior part of this recess is called as the anterior fornix. The texture of this area is similar to the roof of the mouth or the raspberry. This area is very sensitive to pressure. Stimulation of this area instantly lubricates the vagina, even if the woman is previously non responsive to sexual stimulation. To ease the difficulty in reaching this deep area, now-a-days, AFE vibrators are available. It is long and slender angled with an upward curve to reach this area. Some active pupils of sexual physiology of women suggest that multi-orgasms can be achieved if all the four areas of the epicenter (anterior, posterior, and two lateral areas) are stimulated repeatedly one by one. But it really requires a well informed, skilled and concerned partner to do this to a woman.

            Detailed survey and subsequent study points out that around 65% of women do not achieve orgasm during sex by penile insertion. The study also points out only digital or lingual stimulation of the clitoris or vagina brings almost all women to orgasm. When multiple groups of couples were tested with various positions for stimulation of both the G-spot and the A-spot, 75% of the women among the tested groups had sustained vaginal orgasms.   


The vaginal fornices.


            The part of the vagina that is past the cervix and closer to the uterus is called as the vaginal fornix. The ‘fornix’ in Latin means 'vault' or ‘whoredom’ or ‘arch’. There are four sides to this area. The area that is closer to the vesicouterine pouch is called as the AFE zone while the area near the rectovaginal pouch is called as the cul-de-sac. On either sides of the cervix the recesses are called as the lateral fornices. Women vary in their opinions regarding forniceal stimulation. Some say it is arousing while few others say that the cervical touch by finger or penis or vibrator was painful.



Biography of discoverer.

            Dr.Chua Chee Ann, a Malaysian medical doctor, during his research in vaginal dryness identified this AFE zone and he was practicing this for nearly 13 years without publishing his discovery. He graduated from the University of Malaya in 1972 and obtained his masters in Public health from the University of Michigan , U.S.A. After his discovery and subsequent publication, he was invited to many international conferences like the 11th World congress of Sexology. Rio De Janeiro, Brazil, 1994; 3rd Asian Conference of Sexology, New Delhi, India, 1995; Meeting of the Thai, O&G Society, Bangkok, Thailand, 2002; 7th Asian conference of Sexology, Singapore, etc.

            His articles were published in the Journal of British Association for Sex and Marital Therapy, volume 12, No.4, Nov.1997.


 Description of the technique.


            Dr. Chua Chee Ann, in his books and seminars, prescribes applying pressure over the A-spot with scooping movement all around along with simultaneous stimulation of other parts of the vagina for greater sexual stimulation. He says this technique has to be done everyday a week for at-least 5 to 10 minutes per session. He says identification of the spot can be easily done by the starting of the arousal wave and instant lubrication of the vagina. He adds further that by this method intense orgasm can be achieved even with no foreplay.

            The proper technique of A-spot stimulation is to make the woman lie back with knees drawn up (advanced missionary position). Then the index and the middle fingers should be inserted into the vagina. The fingers should slide deep to feel the cervix. The cervix actually feels like the tip of the nose. The fingers should slid past the cervix to feel the spongy area. Then with in and out motion the area should be stroked. The entire area should be covered in circumferential motion. When the pleasure wave arises and when the vagina starts lubricating, one should realize that he or she has hit the area and should cling there for further stimulation.


The deep spot.

            David Shade, a seduction expert, as he names himself, have made a discovery similar to that of Dr.Chua Chee Ann. He identified a spot closer to the uterovesical pouch as erogenous and called it ‘deep spot’. Most likely the AFE and the deep spot are the same. But in his description he has mentioned that the deep spot is present as a cavity inside the cervix. But cervix has no cavity as it is a small straight tube leading to the lower part of the uterus designed to take the deposited sperm into the uterus. But in some other places he mentions that the deep spot is rugged ring like space around the cervix.

            The stimulation technique of deep spot he described is similar to that of Dr. Chua Chee Ann’s technique but varies only in that it involves stimulation of vagina at one place, at one point of time. He mentions the anterior part of the deep spot around the same area where AFE is located while he describes the posterior part around the cul-de-sac.                       



Misunderstandings of site.

            The A-spot is identified to be around the top most part of the vagina where it curves up to join the superior portion of the cervix. Some enthusiasts of the topic say that this deep spot is located at the posterior fornix, just against the G-area. But Dr. Chua Chee Ann shuns that all these claims were wrong. Some others say that this area in the posterior fornix could be another erogenous area discrete from the A-spot.


Relation to female genital anatomy.

            According to some people’s belief, this AFE zone and the anterior fornix are one and the same while some others believe that this zone is the area of degenerated female prostate contrary to the popular belief that the Skene’s glands and the G-area are the female prostate. Some experts believe that this area is a vortex of vaginal nerves and thereby explain the phenomenon of orgasm on stimulation of that area. Some theorize that the vesicouterine and the rectovaginal pouch possess the erogenous properties. 


Physiology of lubrication.

            As per Dr. Chua Chee Ann, stimulation of the A-spot redirects the ejaculatory fluid from the female prostate into the vagina, thereby lubricating the area. The vortex of nerves causes the arousal while the lubrication helps in better stimulation causing a complete sensual excitation promptly.


Orgasm through A-spot stimulation.            

            Some women say that the orgasm they achieve by this AFE zone stimulation is different from the clitoral orgasm, while some others say they are the same. Some women claim that orgasm by this method is stronger.
