The G-spot called the Gräfenberg spot, is characterized as an erogenous area of the vagina that, when stimulated, may lead to strong sexual arousal, powerful orgasms and potential female ejaculation. It is reported to be located 5–8 cm up the front vaginal wall between the vaginal opening and the urethra and is a sensitive area that may be part of the female prostate; the existence of the G-spot has the source of female ejaculation. Although the G-spot has been studied since the 1940s, disagreement persists over its existence as a distinct structure and location; the G-spot may be an extension of the clitoris, which together may be the cause of orgasms experienced vaginally. Sexologists and other researchers are concerned that women may consider themselves to be dysfunctional if they do not experience G-spot stimulation, emphasize that not experiencing it is normal. Two primary methods have been used to define and locate the G-spot as a sensitive area in the vagina: self-reported levels of arousal during stimulation, stimulation of the G-spot leading to female ejaculation.

Ultrasound technology has been used to identify physiological differences between women and changes to the G-spot region during sexual activity. The location of the G-spot is reported as being about 50 to 80 mm inside the vagina, on the front wall. For some women, stimulating this area creates a more intense orgasm than clitoral stimulation; the G-spot area has been described as needing direct stimulation, such as two fingers pressed into it. Attempting to stimulate the area through sexual penetration in the missionary position, is difficult because of the particular angle of penetration required. Women need direct clitoral stimulation in order to orgasm, G-spot stimulation may be best achieved by using both manual stimulation and vaginal penetration. Sex toys are available for G-spot stimulation. One common sex toy is the specially-designed G-spot vibrator, a phallus-like vibrator that has a curved tip and attempts to make G-spot stimulation easy. G-spot vibrators are made from the same materials as regular vibrators, ranging from hard plastic, silicone, jelly, or any combination of them.

The level of vaginal penetration when using a G-spot vibrator depends on the woman, because women's physiology is not always the same. The effects of G-spot stimulation when using the penis or a G-spot vibrator may be enhanced by additionally stimulating other erogenous zones on a woman's body, such as the clitoris or vulva as a whole; when using a G-spot vibrator, this may be done by manually stimulating the clitoris, including by using the vibrator as a clitoral vibrator, or, if the vibrator is designed for it, by applying it so that it stimulates the head of the clitoris, the rest of the vulva and the vagina simultaneously. A 1981 case study reported that stimulation of the anterior vaginal wall made the area grow by fifty percent and that self-reported levels of arousal/orgasm were deeper when the G-spot was stimulated. Another study, in 1983, examined eleven women by palpating the entire vagina in a clockwise fashion, reported a specific response to stimulation of the anterior vaginal wall in four of the women, concluding that the area is the G-spot.

In a 1990 study, an anonymous questionnaire was distributed to 2,350 professional women in the United States and Canada with a subsequent 55% return rate. Of these respondents, 40% reported having a fluid release at the moment of orgasm, 82% of the women who reported the sensitive area reported ejaculation with their orgasms. Several variables were associated with this perceived existence of female ejaculation; some research suggests that clitoral orgasms are of the same origin. Masters and Johnson were the first to determine that the clitoral structures surround and extend along and within the labia. Upon studying women's sexual response cycle to different stimulation, they observed that both clitoral and vaginal orgasms had the same stages of physical response, found that the majority of their subjects could only achieve clitoral orgasms, while a minority achieved vaginal orgasms. On this basis and Johnson argued that clitoral stimulation is the source of both kinds of orgasms, reasoning that the clitoris is stimulated during penetration by friction against its hood.

Researchers at the University of L'Aquila, using ultrasonography, presented evidence that women who experience vaginal orgasms are statistically more to have thicker tissue in the anterior vaginal wall. The researchers believe these findings make it possible for women to have a rapid test to confirm whether or not they have a G-spot. Professor of genetic epidemiology, Tim Spector, who co-authored research questioning the existence of the G-spot and finalized it in 2009 hypothesizes thicker tissue in the G-spot area. Supporting Spector's conclusion is a study published in 2005 which investigates the size of the clitoris – it suggests that clitoral tissue extends into the anterior wall of the vagina; the main researcher of the studies, Australian urologist Helen O'Connell, asserts that this interconnected relationship is the physiological explanation for the conjectured G-spot and experience of vaginal orgasms, taking into account the stimulation of the internal parts of the clitoris during vaginal penetration.

While using MRI technology, O'Connell noted a direct relationship between the legs or roots of the clitoris and the erectile tissue of the "clitoral bulbs" and corpora, the distal urethra and vagina. "The vaginal wall is, in fact, the clitoris," s

Magnesium gluconate is a compound with formula MgC12H22O14. It is the magnesium salt of gluconic acid. According to one study, magnesium gluconate showed the highest level of bioavailability of any magnesium salt which implies its viability as a supplement, although of the 10 salts studied, all increased Magnesium levels significantly, it has E number "E580". There are data on the pharmacological properties of magnesium gluconate. Gluconic acid is the initial substrate for the reactions of pentose phosphate path of oxidation of glucose, so it was suggested that it may affect the energy metabolism of mitochondria. In Ukraine, magnesium gluconate, together with potassium gluconate in the drug Rhythmocor is used to treat heart disease. Pilot studies have shown efficacy in various cardiac arrhythmia. Whether these effects are from the influence of gluconic acid on the metabolism of the heart or from the influence of magnesium and potassium on osmotic pressure is unknown
