I remember that the ancient sage Confucius once said that food and sex are human nature. When we have solved the problem of food and clothing, we will naturally think of sexual desire. This is the social reality. Therefore, when we face problems related to sex, we should accept them generously and reasonably. Grafberg and Dickens first described this erogenous zone in 1944, and he further elaborated on this area in the International Journal of Sexology in 1950. He wrote: "There is always a sexually sensitive area along the urethra on the anterior wall of the vagina. This sexually sensitive area seems to be surrounded by erectile tissue... During sexual stimulation, the female urethra begins to expand, and people can clearly feel that the sensitive area grows and protrudes into the vagina. When the peak of orgasm comes, it swells extremely and protrudes outward. After the orgasm, it returns to its original size." In fact, as early as 1672, a Dutch anatomist Graf introduced a glandular body or female "prostate". He pointed out that its function is to produce mucous serous secretions that can enhance female sexual desire. He has noticed that the pleasure produced by the female "prostate" when secreting this fluid is consistent with the pleasure caused by stimulating the male prostate. If men's prostate is massaged continuously, they can experience ejaculation and orgasm, so some people have proposed that men have two types of orgasms: penile orgasm and prostate orgasm. In 1978, Sefri and Bennett published a review entitled "On Female Ejaculation and the Female Prostate", in which they established that women do have a paraurethral or periurethral structure that swells during sexual stimulation. After learning of this theory, many gynecologists questioned why we have never discovered this structure clinically? Some explained that it is impossible to find it through routine gynecological examinations because the G-spot will only swell when it is fully stimulated, which is the same reason why urologists rarely see men's penis erection. The size of the G-spot varies from person to person, but is generally about the size of a coin. Reports indicate that the G-spot of postmenopausal women generally shrinks. The existence of the G-spot can be confirmed by stroking and stimulating the front wall of the vagina on both sides of the urethra with the index finger or the index and middle fingers. It often helps if you apply pressure above the pubic bone with your other hand. Women first report a feeling of urinary urge, but this feeling will quickly pass and turn into a feeling of sexual interest, which is often a completely new sensation for many subjects. At this time, the G-spot area begins to become solid, but has not yet become a whole. As stimulation of the G-spot continues, it will become as firm as rubber and feel particularly like prostate tissue. If stimulation continues and women reach orgasm, some women will ejaculate streams of liquid from the urethra. About 10-40% of women can ejaculate. Grafberg pointed out that "clonic fluid discharge often occurs at the peak of orgasm, and the two occur almost simultaneously. ... I tend to believe that the so-called 'urine' discharged during female orgasm in the literature is not real urine, but the secretion of the glands in the urethra. These glands are closely related to the sexually sensitive areas of the anterior wall of the vagina along the urethra." He put forward two assumptions: he believed that the female genitals also have spongy erectile tissue, so the anterior wall of the vagina will swell due to vascular congestion during sexual excitement; at the same time, the secretions of the female paraurethral glands will be equivalent to the prostatic fluid of men. These assumptions seem to be consistent with the development process of the human embryo. It is worth mentioning that Zhang Jingsheng, a modern sexologist in my country, proposed as early as the 1920s that women can ejaculate a "third kind of water" during orgasm. In 1981, Adhiago reported the results of an analysis of ejaculated fluid and urine samples from volunteers. The subjects were not allowed to come into contact with semen within 48 hours. They collected the samples at home, froze them immediately and sent them for testing quickly. The urea and creatinine levels in the ejaculate were significantly lower than those in the urine specimens, while the prostatic acid phosphatase and glucose levels were higher than those in the urine. This male-specific enzyme has never been detected in women before, but prostaglandins have never been found in ejaculate. Some scientists found that 10 out of 27 infertile women had orgasm and ejaculation after stimulating their G-spot. The fructose level in ejaculate is significantly higher than that in urine, but is still 10-15 times lower than the fructose content in male semen. Since the female reproductive system is also supposed to have the function of ensuring sperm survival and motility, it makes sense that female ejaculate would contain fructose. Another characteristic of female ejaculation orgasm is that the uterus descends to the vaginal opening, the upper part of the vagina is significantly tightened to form the "frame effect" described by Whipple and Perry, and the anterior wall of the vagina is significantly convex. This is completely different from the description of Masters and Johnson that the uterus rises into the false pelvis and forms a "tent effect" with the expanded upper vagina. They speculate that the two different types of orgasms are controlled by two different types of nerves: clitoral orgasm is stimulated by the pudendal nerve, while ejaculation orgasm is controlled by the pelvic and hypogastric nerves. Whipple participated in a collaborative study attempting to confirm the existence of the G-spot. The operation was performed by two female gynecologists who had heard of the G-spot but did not know much about it. They had neither prejudice nor strong belief in the G-spot, and Whipple gave them guidance before the examination. They examined a total of 11 women, performing gynecological examinations before and after the subjects' partners stimulated their G-spots. They found sensitive spots in 4 women, located between 11-13 o'clock, ranging in size from 2-4 cm, and with a hardness similar to that of a general swelling. Six of the women in this study ejaculated, but laboratory tests showed that the biochemical properties of ejaculate and urine were similar. For example, there was no evidence that the level of prostatic acid phosphatase was higher in ejaculate than in urine. In fact, the level of this enzyme in urine of three women was higher than that in ejaculate samples. Since the results of this study are different from those previously reported, more research is needed in this area because the sample size is too small to make any conclusive judgments. The differences in these laboratory studies seem to be related to the quality of the samples collected. Because the external sphincter of the female bladder is weak, the ejaculate may contain different proportions of urine in addition to the paraurethral gland fluid, so the test results will be quite different. Autopsy studies have shown that there is indeed glandular tissue opening into the urethra in the G-spot area, but the number of autopsies is too small and the results are inconsistent. The gland is rich in prostatic acid phosphatase and is surrounded by a complex network of blood vessels, the urethra and its glands, nerve endings, and tissue surrounding the bladder neck. The results of electron microscopy studies show that the molecular structures of prostatic acid phosphatase in men and women are different, and there are changes within the molecules, so it is relatively easy to distinguish between the two. This discovery has had a significant impact on forensic research. Generally speaking, people use the presence or absence of prostatic acid phosphatase to determine whether sexual assault and sexual injury have occurred. The existence of the G-spot and the phenomenon of ejaculation have many clinical implications. When a couple just reads the news about the G-spot, they will inevitably be excited to try to confirm its existence and location. However, some couples become disappointed because their search proves to be fruitless, which causes them to feel frustrated and have operational anxiety. At this time, we should point out to them the diversity of sexual feelings and responses. It is best not to set any established goals on sexual issues, and do not think that not having ejaculation and not finding the G-spot are abnormal. Regardless of how the final study determines the composition or source of ejaculate, people can draw the following conclusions from the current research: Firstly, many women ejaculate or secrete or 'leak' a secretion during orgasm, a finding confirmed by more than 5,000 letters received after a discussion of the G-spot on US television. Secondly, women who are able to ejaculate often feel uneasy and ashamed about it, thinking it is urinary incontinence, but when they realize that others experience this phenomenon, they become less nervous. They began to realize that this phenomenon represents a more interesting way of sexual response, whereas in the past they had always tried hard to suppress their orgasmic performance in order to avoid being looked down upon by men ("urinating"). Finally, when it is clear that the "patient"'s stress incontinence occurs only during orgasm, surgical treatment of the incontinence is no longer necessary. It should be explained to these women that this is a common problem for many women and that no surgical treatment is necessary. An interesting finding was that the pubococcygeus muscles of women who were able to ejaculate were much stronger than those of women who were unable to ejaculate. And when women complain of urinary incontinence during orgasm, doctors often tell patients to follow Kegel exercises to strengthen the strength and conditioning of their pubococcygeus muscles, which is counterproductive. It is not clear whether the G-spot is related to the orgasm platform in the outer third of the vagina, or whether they are different parts of the same area or two separate, unconnected areas. The outer 1/3 of the vagina is the orgasm platform, while the G-spot is in the middle 1/3 of the vagina. However, the basic congestion and swelling of the physiological reactions of the two are the same. Past medical theories always emphasized that the nerve distribution of the vagina is limited to the outer 1/3, while there are very few nerve endings in the inner 2/3, so there is no special feeling. However, the G-spot happens to be located in the middle 1/3. Why is this point so sensitive? Is there an area with dense nerve endings similar to the prostate nerves? It seems that the debate surrounding the G-spot and female orgasm ejaculation will continue, and people can only uncover this mystery through more in-depth research. |
