Vaginal Stem Cell Therapy vs PRP: What Is the Difference?
PRP is platelet-rich plasma: your own blood, spun the same day to concentrate platelets and growth factors, containing no stem cells. Stem cell therapy means living cells, taken from fat or bone marrow and often cultured in a laboratory, or donor-derived. PRP is cheaper, lower-risk and slightly better studied; cultured cells face strict Korean regulation and unknown long-term effects. Neither is proven, and neither repairs structural laxity. Somssi Women's Clinic in Gangnam explains both.

Key facts
The essentials, based on how Somssi Women's Clinic performs this procedure or answers this question. Your plan is confirmed at consultation.
- PRP source: Your own blood, prepared in minutes, same day
- Stem cell source: Your fat or bone marrow, or donor cells, often cultured for weeks
- Contains stem cells? PRP no; cell therapy yes
- Evidence: Both investigational; PRP has more small studies
- Regulation in Korea: PRP performed as a procedure with approved kits; cultured cells are regulated cell-therapy products
- Durability: Both temporary; neither tightens muscle or lifts a prolapsed uterus
- Reviewed by: Dr. Yoon Ho-joo, MD, PhD, OB/GYN specialist
PRP and vaginal stem cell therapy differ in what is injected: PRP is a concentrate of your own platelets and growth factors with no cells in it, while stem cell therapy uses living cells, usually harvested from fat or cultured in a laboratory. Many clinics blur the two by calling PRP a stem cell treatment. Knowing the difference protects your health and your wallet.
What PRP is
Platelet-rich plasma is prepared by drawing a small volume of your blood and spinning it in a centrifuge so the platelets concentrate in one layer. Platelets are cell fragments that carry growth factors, the signals your body uses to heal wounds. The concentrate is injected into the vaginal wall, vestibule or clitoral area within the hour.
Because PRP is your own blood, minimally processed and used immediately, it carries low risk and modest cost. The O-Shot is a branded PRP protocol aimed at sensation and mild stress incontinence.
What stem cell therapy is
Stem cell therapy means injecting living cells with the potential to develop into other cell types. In gynecology marketing it usually refers to one of three things: fat harvested by liposuction and injected whole or lightly processed, which contains a small fraction of stromal stem cells; cells taken from your fat or bone marrow and expanded in a laboratory over weeks; or cells from a donor source such as umbilical cord tissue.
Each is a different product with different risks. Laboratory-cultured and donor-derived cells are regulated in Korea as cell therapy products under the Ministry of Food and Drug Safety, and approval for vaginal injection is generally not something a clinic can show. See what vaginal stem cell therapy is for a fuller explanation of each.
Side-by-side comparison
| Feature | PRP | Stem cell therapy |
|---|---|---|
| What is injected | Concentrated platelets and plasma | Living cells: fat-derived, cultured or donor |
| Contains stem cells | No | Yes |
| Preparation | Blood draw and centrifuge, same day | Fat harvest same day, or weeks of laboratory culture |
| Proposed action | Growth factors stimulate repair | Cells release growth factors and may integrate into tissue |
| Evidence for vaginal use | Small studies, some randomized, short follow-up | Case series and very small studies |
| Main risks | Soreness, bruising, rare infection, no benefit | As PRP plus contamination, immune reaction, unwanted tissue growth, unknown long-term effects |
| Regulation in Korea | Procedure using MFDS-approved preparation kits | Regulated cell therapy product; approval for vaginal use generally absent |
| Cost | Lower | Higher, especially for cultured cells |
| Durability | Months; repeated | Unknown; claimed longer, not demonstrated |
| Fixes structural laxity or prolapse | No | No |
Why the words get mixed up
'Stem cell' sells. PRP contains growth factors, and growth factors are involved in how stem cells behave, so some clinics describe PRP as 'stem cell activating' or simply as stem cell therapy. Others mix PRP with fat and call the mixture stem cell treatment. There is no deception in using PRP; the problem is pricing or promising it as something it is not.
A simple test: ask whether the product contains living cells. If the answer is no, it is not stem cell therapy, whatever the brochure says.
Which is better?
For most women who are reasonable candidates for a regenerative injection, PRP is the more sensible choice: lower cost, lower risk, same-day preparation from your own body, and a slightly larger, though still weak, evidence base. Cultured stem cells add expense and uncertainty without demonstrated extra benefit in vaginal tissue, and they raise regulatory questions that your own blood does not.
The more important point is that neither treats the problems women most often hope to fix. A loose vagina, a descended uterus or a gaping perineum are structural and need surgery. Dryness from menopause is hormonal and responds best to estrogen. Our guide on whether these treatments are proven sets out the evidence.
How Somssi approaches the choice
Somssi Women's Clinic is a surgical gynecology clinic in Gangnam, Seoul, founded in 2000 and led by Dr. Yoon Ho-joo, MD, PhD. We do not inject cultured stem cells into the vagina. Our intimate regenerative options use your own plasma or fat, with every ingredient named in writing, and our stem cell program is an intravenous autologous NK immune-cell program unrelated to vaginal treatment.
Before any recommendation, Dr. Yoon takes a sexual-function history, measures the vagina, tests the pelvic floor and scans the pelvis. If the finding is a thin, dry lining in a well-supported vagina, a plasma-based or hormonal option is discussed. If the finding is a stretched posterior wall or a descended uterus, we explain autologous-tissue vaginoplasty, which thickens the wall with your own tissue and restores support, and why no injection would do the same.
Bottom line
PRP is your own platelets, prepared the same day, with no stem cells in it; stem cell therapy uses living cells with more cost, more regulation and more unknowns. If a regenerative injection is reasonable for you, PRP is usually the better-judged option. If your problem is structural or hormonal, neither is the answer. Contact Somssi for an examination that sorts out which applies to you.

Questions patients ask
Frequently asked questions
Short, honest answers. For anything personal, a consultation is the right place to ask.
Is PRP a type of stem cell therapy?
No. PRP contains platelets, which are cell fragments carrying growth factors, and plasma. It contains no stem cells. Clinics sometimes market it as stem cell therapy because growth factors influence cell behavior, but the two are different products with different risks, regulation and prices.
Does stem cell therapy last longer than PRP?
That is claimed but not demonstrated in vaginal tissue. Both are investigational and both are usually repeated. Cultured cells cost more and carry more unknowns, so paying extra for a longer effect that has not been shown is a poor bargain. Durable change in vaginal structure comes from surgery, not from either injection.
Can PRP and stem cells be combined?
Some clinics mix PRP with fat and call the mixture a stem cell treatment. Combining products makes it impossible to know what helped and adds the risks of each. If you are offered a combination, ask for every component to be named and its approval status shown.
Which has more side effects?
PRP has mainly short-term local effects: soreness, bruising, spotting. Cultured or donor cells add the possibility of contamination, immune reaction and unwanted tissue growth, with unknown long-term rates. Fat transfer adds harvest-site bruising and partial absorption. None of these is a reason to panic, but all are reasons to know what you are receiving.
Does Somssi offer PRP or stem cells?
Somssi offers plasma-based and fat-based options prepared from your own body, with full disclosure, and does not inject cultured stem cells into the vagina. Our NK immune-cell program is an intravenous immune-support treatment, not a vaginal one. For structural problems we recommend autologous-tissue surgery.
