What is the “O-shot” (PRP for sexual function) in clinical terms?
The “O-Shot” is a trademarked name for autologous platelet-rich plasma (PRP) injection therapy administered into the clitoris and anterior vaginal wall. It aims to enhance sexual arousal, improve orgasmic function, and reduce stress urinary incontinence by promoting tissue regeneration and nerve sensitivity through growth factors released from concentrated platelets. While emerging evidence shows promise, it remains an evolving treatment with variable outcomes and is not yet covered by NHS or most insurers.
Show Detailed Answer
The O-Shot involves drawing a small amount of your own blood, processing it in a centrifuge to separate and concentrate the platelets, then injecting this platelet-rich plasma into specific areas around the clitoris and the upper vaginal wall (often near the urethral opening and G-spot region). The procedure typically takes 30–45 minutes and is performed under topical anaesthetic cream to minimise discomfort.
Platelets contain multiple growth factors—including vascular endothelial growth factor (VEGF), platelet-derived growth factor (PDGF), and transforming growth factor-beta (TGF-β)—that theoretically stimulate angiogenesis (new blood vessel formation), collagen production, and nerve regeneration. The rationale is that improved blood flow and tissue vitality in these sensitive zones may enhance clitoral engorgement, vaginal lubrication, orgasmic intensity, and urethral support.
The Science: How PRP Works in Regenerative Medicine
PRP has been used for decades in orthopaedics, dentistry, and wound healing. When applied to gynaecology and sexual medicine, the hypothesis is that the growth factors can:
- Increase Local Blood Flow: New capillary formation may improve clitoral and vaginal engorgement during arousal.
- Stimulate Nerve Endings: Potentially heighten sensation and orgasmic capacity.
- Strengthen Connective Tissue: May offer modest structural support to the urethra, reducing mild stress incontinence.
- Enhance Lubrication: Improved tissue health may support natural secretions.
It is important to note that PRP does not contain hormones. It is distinct from oestrogen therapy and does not treat atrophy caused by menopause in the same way localised oestrogen does.
What Happens During the Procedure?
A typical O-Shot session follows this sequence:
- Blood Draw: 10–20ml of venous blood is taken from your arm, just like a routine blood test.
- Centrifugation: The blood is spun at high speed for 5–10 minutes to separate plasma from red and white blood cells.
- Topical Anaesthesia: A numbing cream is applied to the vulva and left for 15–20 minutes.
- Injection: The concentrated PRP is injected using fine needles into the clitoral glans, clitoral hood, and the anterior vaginal wall near the urethra. Multiple small injections are typically made.
- Recovery: You can leave immediately. Mild swelling, tenderness, or spotting may occur for 1–3 days.
Who Might Consider It?
The O-Shot is most commonly sought by women experiencing:
- Difficulty achieving orgasm or reduced orgasmic intensity
- Low sexual arousal or reduced clitoral sensitivity
- Mild stress urinary incontinence (e.g., leaking when coughing or laughing)
- Post-childbirth changes in sexual function
- Menopausal or perimenopausal sexual concerns not fully resolved by hormonal therapy
It is sometimes combined with laser vaginal rejuvenation, pelvic floor physiotherapy, or systemic hormone replacement therapy as part of a broader regenerative wellness plan.
Common Concerns & Myths
“Is it just cosmetic or vanity-driven?”
No. While aesthetic medicine providers do offer it, the clinical aim is functional improvement—better arousal, orgasm, and continence. Many women seek it after childbirth trauma or menopause-related sexual dysfunction, not simply for enhancement.
“Will it hurt? Is it invasive?”
Most patients report minimal discomfort thanks to topical anaesthetic. It is not a surgical procedure, and downtime is typically under 48 hours. Some describe a brief pinching sensation during injection.
“Does it work immediately?”
No. Growth factors take time to stimulate tissue changes. Most clinical protocols suggest assessing outcomes at 6–12 weeks. Some providers recommend a second session at 3–4 months for optimal results.
“Is it FDA or MHRA approved?”
PRP devices and kits are regulated, but the O-Shot itself is not a licensed medication. It is considered an autologous biologic therapy and falls into a regulatory grey zone. Always ensure your provider is medically qualified and follows aseptic technique.
Clinical Context
PRP for sexual function is part of the broader field of regenerative gynaecology, which also includes energy-based treatments (e.g., CO₂ laser, radiofrequency) and stem-cell therapies. While small pilot studies and case series have reported subjective improvements in arousal, orgasm, and incontinence scores, large-scale randomised controlled trials are still lacking. The treatment is not currently recommended in NICE guidelines and is considered investigational by many professional bodies. Patient selection, realistic expectation-setting, and integration with other therapies (pelvic physio, psychosexual counselling, HRT) are essential for success. Educational only. Results vary. Not a cure.
Evidence-Based Approaches
Self-Care & Lifestyle
Before considering PRP, foundational sexual health measures should be optimised:
- Pelvic Floor Training: Strengthening (Kegels) or relaxation exercises can improve both continence and orgasmic function.
- Lubrication & Moisturisation: Use high-quality, body-safe lubricants and vaginal moisturisers to reduce friction and dryness.
- Communication: Open dialogue with your partner about arousal needs, timing, and foreplay can significantly improve sexual satisfaction.
- Smoking Cessation: Smoking impairs microcirculation and may reduce the efficacy of regenerative therapies.
Medical & Specialist Options
Clinical pathways for sexual dysfunction typically include a stepwise approach:
- Hormonal Assessment: Check oestrogen, testosterone, and thyroid function. Topical oestrogen is first-line for menopausal atrophy.
- Pelvic Floor Physiotherapy: Specialist physios can assess tone, teach relaxation techniques, and address vaginismus or overactive muscles.
- Psychosexual Therapy: Cognitive-behavioural therapy (CBT) or sex therapy addresses anxiety, trauma, and relationship dynamics.
- Energy-Based Devices: CO₂ fractional laser or radiofrequency may complement PRP by stimulating collagen and improving vaginal tissue quality.
- PRP (O-Shot): Typically positioned as an adjunct for women with mild-to-moderate functional concerns who have not fully responded to conservative measures.

C. Red Flags (When to see a GP)
Seek medical review if you experience persistent pelvic pain, unexplained bleeding, painful urination, or new-onset incontinence. These may indicate infection, prolapse, or other conditions requiring investigation before considering elective procedures.

Clinical Insight: The O-Shot is not just for "libido." It is a regenerative therapy using Angiogenesis (new blood vessels) and Neurogenesis (new nerves) to treat atrophy and Lichen Sclerosus. However, taking Ibuprofen near your appointment will chemically block the treatment from working.
Additional Clinical Details
Clinically, the O-Shot is an Autologous Platelet-Rich Plasma (PRP) injection. It works by tricking the body into thinking there is an injury, triggering a massive repair response.
The "Alpha Granule" Release
- What happens: When platelets are activated, they degranulate, releasing powerful growth factors like PDGF (Platelet-Derived Growth Factor) and VEGF (Vascular Endothelial Growth Factor).
- Angiogenesis: VEGF stimulates the growth of new capillaries, increasing blood flow to the clitoris and vaginal walls. This directly combats dryness and atrophy.
- Neurogenesis: The factors stimulate the repair and growth of new nerve endings, which improves sensitivity and the sexual response cycle.
Beyond sexual function, PRP is increasingly used as a second-line therapy for Vulval Lichen Sclerosus (LS).
- Tissue Regeneration: Unlike steroids (which only suppress inflammation), PRP encourages the regeneration of healthy tissue in areas scarred or thinned by LS.
- Symptom Relief: Clinical studies show improvements in itching and pain for patients who have stopped responding to standard steroid creams.
The procedure targets two specific anatomical sites for maximum efficacy:
- The Clitoral Body: Not just the visible glans, but the body of the clitoris to enhance nerve sensitivity.
- The Anterior Vaginal Wall (O-Spot): The area often referred to as the "G-Spot" (Skene's Glands), to increase tissue thickness and lubrication.
Why you must stop Ibuprofen
- The Chemistry: NSAIDs (Anti-inflammatories like Ibuprofen, Aspirin, Naproxen) block the exact pathway (Cyclooxygenase) that platelets use to release their growth factors.
- The Rule: You must avoid these medications for 5–7 days before and 5–7 days after your treatment. Taking them will neutralize the effect of the O-Shot.
- Alternative: Paracetamol is safe to use as it does not affect platelet function.
