G-Shot: How to Avoid Complications—The Basics of Vaginal Hyaluronic Acid, Safety, and Choosing a Doctor
After engaging in general obstetrics and gynecology practice, including infertility treatment, perinatal care, and other insured treatments, I decided to shift my career to free practice and gynecological aesthetics, with the hope of “supporting women to enjoy their life as a woman” after my own experience fighting against illness. Today, while still being involved in insured medical care as an obstetrician/gynecologist, I am facing women's health issues based on medical evidence through "real femtec" such as gynecologic plastic surgery, Vaginal Growth® injections, and vaginal hyaluronic acid injections, based on my deep anatomical knowledge and skills. We are a leading provider of gynecological services in Japan.
She is also committed to social activities related to the dissemination of sex education, HPV vaccine awareness, and the improvement of women's quality of life. He is also actively involved in educating the public about medical knowledge, such as writing Chapter 7, "Vaginal Hyaluronic Acid Injection," in his specialty book, "The Basics of Cosmetic Surgery," which is the first book he reads when he becomes a cosmetic surgeon.
"I'm thinking about getting a G-shot, but what if it doesn't work out?"—I often hear people express this kind of anxiety.
There is a wealth of information available, particularly about Tokyo and Ginza, and while the benefits tend to leave a strong impression, the pitfalls and risks to avoid often go unnoticed.
In this article, we’ll explain the mechanism behind vaginal hyaluronic acid injections (commonly known as “G-Shots”) in simple, easy-to-understand terms from a professional perspective. We’ll also carefully outline strategies to minimize the risk of perceived “failure” and provide guidance on how to choose a doctor to ensure your procedure is safe—including tips on finding one in Ginza, Tokyo.
Keeping in mind that results, pain, downtime, and duration of effects vary from person to person, we provide information that will put your mind at ease so you can feel comfortable “asking for a consultation.”
[Doctor’s Point]
The first thing I want to make clear is that the G-Shot is not a “magic injection.”
Whether you’re receiving treatment in Tokyo, Ginza, or anywhere else, it’s very important to thoroughly understand the clitoris—the center of sexual sensation—as well as the anatomy of the vagina and the condition of your pelvic floor, so you can determine the approach that’s right for your body.
What Is a G-Shot? How It Works and Common Misconceptions
A "G-shot" is a procedure in which a small amount of hyaluronic acid is injected into a part of the anterior vaginal wall—commonly known as the "G-spot"—to create a slight bulge, making it easier for a finger or penis to make contact with it.
Simply put, the goal is to influence sensitivity by altering “ease of stimulation (contact)”; it does not directly create sexual sensation itself.
If you misunderstand this point, your expectations may get ahead of you, making it easy to feel like you've "failed the G-shot."
Anatomy of the Clitoris and Basics of Sexual Response
The clitoris shares the same embryological origin as the male genitalia and has similar functions.
Not only are there small parts visible from the outside, but inside, the legs (leg sections and leg columns) and the corpus spongiosum extend throughout the area, and they react to sexual arousal by increasing blood flow.
For many people, reaching orgasm through penetration alone is not easy, so stimulating the clitoris (foreplay) is important.
In other words, if you focus solely on the G-spot without sufficient foreplay or mental preparation, it doesn't necessarily mean your sensitivity will increase dramatically.
The G-Shot is a "technique designed to make it easier to reach orgasm"; it is not meant to replace the underlying arousal response (clitoral response).
Situations That Are Easily Perceived as G-Shot Failures
There are various reasons why people may feel that the treatment has failed. For example, “I don’t feel as much of a change as I expected,” “I experienced discomfort or pain,” or “It actually feels uncomfortable during intercourse.”
In many cases, the underlying causes include a failure to properly assess suitability, inaccuracies in the injection site or depth, excessive injection volume, and overlooking pelvic floor issues (such as prolapse or mild cystocele).
If your expectations are too high, or if there is a lack of communication or foreplay with your partner, the sensation may feel lacking, and you may be more likely to feel like you've "failed to achieve the G-shot."
A Simple Guide to the Indications and Contraindications of Vaginal Hyaluronic Acid
Guidelines for Who This Is Suited For
-
For those who enjoy the pleasure of clitoral stimulation but want to enhance the "feeling of contact" during penetration a little more
-
For those who feel that stimulation in a specific area of the anterior vaginal wall is lacking and would like to try adjusting the intensity slightly
-
Individuals who can understand the explanation provided by a specialist after a comprehensive evaluation of their sexual function, including its underlying factors (hormones, pelvic floor, and psychological aspects)
People who want to consider this carefully
-
Women who have or are suspected of having pelvic organ prolapse or sagging after childbirth (injection may worsen the sagging)
-
People with stress urinary incontinence (who may have a cystocele, which can be exacerbated by irrigation)
-
People whose primary goal is to improve urinary incontinence (Note: The G-Shot is not a treatment for urinary incontinence)
-
People who are strongly advised to undergo deep injection (as described below, this carries a high risk and makes the procedure more difficult)
Injection Sites and Techniques—Important Considerations for Safety
Reasons Not to Inject Deep into the Vagina
The inner part of the vagina is naturally spacious, and it expands even further during orgasm. Therefore, the idea that “since it’s spacious inside, you can go deeper” doesn’t make sense.
In fact, the deep parts of the vagina and the areas at the 3 o'clock and 9 o'clock positions on either side have a rich blood supply, which increases the risk of embolism (blockage of a blood vessel) and other complications.
Since it is difficult to maintain a clear line of sight in the deep layers and to manage complications if they arise, you should exercise caution with doctors who readily recommend deep injections.
There is little clear benefit to creating an uneven surface like a herring roe ceiling, and it may only increase the risks.
The vagina is H-shaped—injecting horizontally is dangerous and serves little purpose.
The vagina is shaped like the letter "H." Injections designed to add volume horizontally not only increase the risk by going against the body's natural anatomy but are also unlikely to improve the sensation.
Let's prioritize safety and consider the minimum necessary scope and quantity.
You should avoid G-shots intended to treat urinary incontinence
If too many G-Shots are administered to individuals with stress urinary incontinence, it may cause the anterior wall to prolapse further, leading to discomfort and a worsening of symptoms.
If you have a bladder hernia, your risk of the condition worsening is even higher. Be cautious of clinics that advertise treatments for urinary incontinence.
Although there is plenty of information available in Tokyo and Ginza, urinary incontinence is generally evaluated and treated at women’s urology clinics or OB/GYN clinics that specialize in pelvic floor disorders; therefore, the G-Shot should not be considered an appropriate treatment for this condition.
Key Points for Choosing Materials—Fillers That Don’t Melt Are a No-Go
Although they are marketed as “hyaluronic acid,” some injectables used actually do not dissolve or remain in the body for years.
These materials are difficult to remove in cases of infection, obstruction, or the formation of lumps, and they can also affect pregnancy and childbirth plans as well as the risk of future prolapse.
We recommend that you avoid seeing any doctor—even a specialist—who uses non-dissolving fillers.
As a basic safety precaution, you should choose only approved medical-grade hyaluronic acid, which can be dissolved with hyaluronidase in the event of an emergency.
Choosing a Doctor or Clinic
The key is to choose an obstetrician-gynecologist or a female urologist who can thoroughly examine the anatomy of the pelvic floor and the pelvic floor muscles.
While Tokyo offers a wide range of options, which is reassuring, it can also make it difficult to discern the right choice. There are doctors who, although they once practiced in obstetrics and gynecology, have since switched to cosmetic surgery but still present themselves as obstetricians and gynecologists, as well as doctors who claim to specialize in women’s health despite having no experience in obstetrics, gynecology, or female urology.
Furthermore, even among urologists, there are some who have little to no experience with female urology; in such cases, it cannot be said that they have sufficiently honed their skills in women’s healthcare.
Be sure to verify their qualifications, professional affiliations, and specific experience in treating women’s pelvic floor conditions.
It’s reassuring to check whether medical facilities certified by professional societies in Tokyo and specialized clinics in the Ginza area disclose information about their treatment services, surgical history, and experience in female urology.
How to Interpret "Before & After" Images and Manage Expectations
The "Before & After" photos are just a reference; however, sensitivity and pain perception vary greatly from person to person, so the experience can differ even with the same injection volume.
Don’t base your decision solely on photos or personal accounts; be sure to discuss your own pelvic floor condition, vaginal anatomy, clitoral response, and even your relationship with your partner.
Information portals for Tokyo and Ginza are convenient, but their advertising claims tend to be exaggerated. Please place importance on the personalized explanations you receive during your consultation.
Estimated Downtime, Complications, and Duration
Mild swelling and discomfort usually subside within a few days to a week, though this varies from person to person.
Bruising, lumps, infection, excessive volume, and embolism are theoretically possible.
The duration of the effects varies depending on the formulation used, the dosage, and individual metabolism, but they are not permanent. If you experience any concerning symptoms, please contact your treating physician as soon as possible.
Frequently Asked Questions (Common Questions Raised During Consultations in Ginza, Tokyo)
Will this help with urinary incontinence?
Urinary leakage, particularly postpartum stress urinary incontinence, may be associated with a bladder prolapse or anterior wall prolapse.
G-Shots should be avoided because they are not a treatment for urinary incontinence and may actually make the condition worse.
If you see an advertisement in Tokyo or Ginza that mentions urinary incontinence, please first seek an evaluation at a women’s urology clinic or an obstetrics and gynecology clinic that specializes in pelvic floor disorders.
I'd like to improve my sexual function. How can I do that?
Sexual function is determined by a combination of clitoral response, pelvic floor tension and relaxation, a sense of psychological security, and communication with your partner.
The G-shot is one of several techniques designed to make it easier to achieve orgasm. Without sufficient foreplay and caressing, the physical sensations will be limited. Consult a specialist with expertise in sexual function to discuss the issue from a holistic perspective.
Where should I go for advice in Ginza, Tokyo?
Choose a medical facility staffed by an obstetrician-gynecologist who can evaluate the pelvic floor and pelvic floor muscles, or one that specializes in female urology and clearly states its experience in treating female urological conditions.
It’s reassuring to look for indicators such as accreditation by a public medical association in Tokyo or whether a clinic in the Ginza area offers outpatient services for women’s pelvic floor issues.
Summary
The G-Shot is an option for improving the "responsiveness" of the anterior vaginal wall; it is not intended to replace the clitoral response, which forms the foundation of sexual sensation, or the condition of the pelvic floor.
Injections into deep tissues or in a lateral direction carry high risks and should be avoided for the treatment of urinary incontinence.
Avoid using non-dissolvable fillers, and make your decision with an eye toward pregnancy, childbirth, and future sagging. Prioritize suitability and safety.
Advice
If you are considering treatment in Tokyo or Ginza, please consult an OB-GYN or a female urologist who has a thorough understanding of the anatomy of the pelvic floor and sexual function and can tailor treatment to your specific symptoms.
Be wary of doctors who use misleading descriptions of their past positions or who lack sufficient training in women’s health.
If you're wondering whether this is right for you, let's start by having a calm consultation so we can work together to find options that fit your body and lifestyle.
Whether you’re seeing a doctor in Tokyo or Ginza, please make sure to prioritize an environment where you feel comfortable speaking openly.
