Key insights from an educational webinar with Carolyn DeLucia, MD
During a recent educational webinar hosted by APEX Biologix, board-certified obstetrician and gynecologist Carolyn DeLucia explored the clinical landscape of genitourinary syndrome of menopause (GSM) and the emerging use of autologous platelet-rich plasma (PRP), including PRP combined with protein concentrate. The session examined GSM pathophysiology, patient evaluation, procedural considerations, and current clinical evidence, with a focus on how regenerative approaches are being evaluated and applied in practice.Genitourinary syndrome of menopause (GSM), previously referred to as vulvovaginal atrophy or urogenital atrophy, describes a constellation of vaginal, urinary, and sexual symptoms associated with hypoestrogenic states, most commonly postmenopause.
According to Dr. DeLucia, GSM is highly prevalent, affecting a majority of postmenopausal women, though many do not report symptoms unless directly asked. Unlike vasomotor symptoms such as hot flashes, GSM tends to progress over time, driven by sustained estrogen deficiency and reduced blood flow to genital tissues.
Decreased collagen, elastin, and vascularity
Thinning and fragility of vaginal epithelium
Loss of glycogen, contributing to elevated vaginal pH
Increased susceptibility to recurrent UTIs, bacterial vaginosis, and yeast infections
Reduced pelvic floor strength and tissue tone
These changes may contribute to symptoms such as vaginal dryness, dyspareunia, urinary urgency or stress incontinence, reduced sensation, and diminished sexual function often with a significant impact on quality of life.
Dr. DeLucia discussed the importance of proactive, sensitive patient communication while also highlighting that many patients do not volunteer sexual or urinary concerns unless clinicians create a safe and intentional space to ask.
Clinical history may include:
Pain with penetration or entry
Decreased lubrication or sensation
Urinary leakage with coughing, sneezing, or urgency
Vaginal laxity or structural changes following childbirth
Orgasmic dysfunction or reduced sexual satisfaction
Understanding which symptoms are most impactful for the patient helps guide both counseling and procedural planning.
The webinar reviewed a range of therapeutic tools used in GSM management, including:
Local vaginal estrogen and DHEA
Energy-based devices (e.g., radiofrequency)
Autologous fat transfer (with noted invasiveness and risk considerations)
Platelet-rich plasma (PRP) and PRP with protein concentrate (PC)
PRP was discussed as an autologous biologic therapy, derived from the patient’s own blood, processed in-office, and reintroduced to targeted tissues. Because PRP is autologous, it is categorized as an autograft, distinct from allograft or perinatal tissue-derived products.
Dr. DeLucia emphasized that while PRP has been used for decades in orthopedics and other specialties, its mechanisms are still being actively studied. PRP contains platelets rich in alpha granules, which release growth factors and cytokines involved in tissue signaling.
Growth factors discussed included:
Platelet-derived growth factor (PDGF)
Insulin-like growth factor (IGF)
Transforming growth factor-β (TGF-β)
Vascular endothelial growth factor (VEGF)
Fibroblast growth factors
Collectively, these signals are associated with cell proliferation, differentiation, collagen synthesis, and angiogenesis, with angiogenesis highlighted as a key factor in genital tissue health.
A structured timeline for tissue response was outlined:
~3 days: Acute tissue response related to volume and injection
1–3 weeks: Relative lull as early biologic processes begin
3 weeks–3 months: Active tissue remodeling and growth phase
~12 weeks: Peak observed response in many patients
Clear patient education around this timeline was emphasized to support realistic expectations.
The webinar also explored PRP combined with protein concentrate, using APEX processing technology.
Protein concentrate is derived from platelet-poor plasma (PPP), a fraction typically discarded in standard PRP preparation. Using a specialized filtration process, excess plasma water is removed, allowing concentration of naturally occurring anti-inflammatory and regulatory proteins such as:
Alpha-2-macroglobulin (A2M)
Platelet Derived Growth Factor (PDGF)
Soluble cytokine receptors
This concentrated protein fraction may then be recombined with PRP to enrich the biologic environment delivered to tissue.
Injection location was described as indication-dependent, with examples including:
Clitoral tissue for orgasmic dysfunction
Suburethral/anterior vaginal wall for stress urinary incontinence
Vaginal walls for dryness or dyspareunia
Introital and perineal regions for entry pain or scar-related discomfort
Pain-management strategies discussed included topical anesthetics, local anesthetic infiltration, ice, and patient-controlled nitrous oxide, depending on tissue sensitivity and indication.
Multiple studies were reviewed, including:
Pilot and randomized controlled trials evaluating PRP for vulvovaginal atrophy
Studies demonstrating improvement in validated scores such as the Female Sexual Function Index (FSFI) and Vaginal Health Index (VHI)
Reviews assessing PRP in GSM, stress urinary incontinence, pelvic organ prolapse, and lichen sclerosus
Across studies, PRP was consistently described as promising, minimally invasive, and generally well tolerated, with authors uniformly noting the need for larger, standardized trials.
GSM is a progressive condition driven by estrogen deficiency and reduced genital blood flow
PRP is an autologous biologic therapy being actively studied for GSM-related symptoms
Protein concentrate may further enrich PRP by concentrating anti-inflammatory plasma proteins
Clinical evidence to date suggests potential benefit, while emphasizing the need for continued research
Patient selection, counseling, and expectation-setting are critical components of care
