Autologous Fat / Hyaluronic Acid Injection

This technique is frequently performed in young females who are unmarried or without natural birth via vaginal delivery. Because these patients have vaginal muscles and skin with intact elasticity, vaginal mucosal resection or muscular stitching is saved to attain the tightening results, so autologous fat injection is employed to augment the inner wall of the vagina or the periphery of the vaginal opening to enhance the intimacy with male sexual organs during sexual intercourse. In this surgery, adipocytes should first be extracted from other body parts through liposuction and then be radially injected at multiple points and facets and annularly distributed in the vaginal wall. The injection scope extends 5 cm inside the vaginal opening, and the injection depth reaches the superficial tissues between the vaginal mucosa and muscular layer. If a patient has G-spot orgasm disorders, partial fats are also injected to the area near the G-spot to enhance stimulus to the G-spot.

Despite being an economic vaginal augmentation method, fat injection is replaced by the injection of high molecular weight hyaluronic acid (Macrolene or Sub-Q), if the patient does not have excess fats. This method utilizes large-dose hyaluronic acid, whose results last for approximately 6 months and whose costs and benefits greatly differ from those of fat injection.

Surgical conditions


  • Type of anesthesia: IV sedation + local anesthesia
  • Surgical incision: Approximately 4-5 needle holes at the vaginal opening and inner wall
    Wound for liposuction at the abdomen (umbilicus) or medial side of the thigh
  • Recovery: 1–2 days
  • Removal of stitches: No

General instructions

No food and water on the day of surgery

  • Avoid the surgery during the menstrual period.
  • Try to wear loose underclothes for 1 week postoperatively to avoid friction on wounds.
  • Avoid sexual behaviors for 2 weeks postoperatively.
  • Massage the area of liposuction for 1 month.

Ideal candidates

  • Patients with a relatively lax congenital vagina or vaginal opening
  • Those with vaginal slackness due to frequent sexual behaviors
  • Those with vaginal slackness but who have a relatively good contraction and elasticity of vaginal muscles
  • Young patients having no child birth from vaginal delivery
  • Patients with a mild vaginal looseness that has no need to undergo surgical correction
  • Those unable to accept the recovery of vaginoplasty

Potential complications

  • Irregular lumps
  • Fat absorption or loss
  • Uneven surface of the vagina (temporary)
  • Results short of expectation

Surgical advantages

  1. Only needle holes will persist, and no scar will be left on the vagina.

  2. The surgery is minimally invasive and traumatic and needs no period of recovery.

  3. The surgery is painless.

  4. The patient can have sexual intercourse within 2 weeks postoperatively.

  5. It can be repeatedly conducted.

Surgical drawbacks

  1. It can only enhance vaginal intimacy and has no actual tightening effects.

  2. A temporary particular prominence or irregularity may be left on the surface of the vagina.

  3. The self-resorption rate of fat may differ in individuals, and the long-term results are relatively unstable.

  4. Frequent sexual behaviors may accelerate fat or hyaluronic acid loss.

  5. The surgical results and durability cannot be quantified or predicted.

  6. Hyaluronic acid needs to be given every 6 months.
