Part 1 of this article established that the pelvic floor has always been within the acupuncture scope. Our classical texts mapped channels through the pelvis with precision. CV 1 and GV 1 are physically located in the pelvic floor musculature, with indications spanning the full range of conditions our pelvic health patients present with. And the population that needs us, more than 25% of women and more than 15% of men struggling with pelvic pain or dysfunction, is already in our waiting rooms. The case is clear. Now let us look at what the research shows.
What the Research Tells Us
The body of research supporting acupuncture for pelvic health conditions has grown substantially over the past decade. The evidence is not perfect, and where methodological limitations exist, honesty requires us to say so. But the trajectory is clear, and the strongest studies are worth knowing well.
Overactive Bladder and Urinary Incontinence: Many of us have seen a client who uses pads for leak protection, who plans her route before she leaves the house based on where the bathrooms are, who declines invites to avoid embarrassment. A 2024 umbrella review in the Arab Journal of Urology, the highest available level of evidence synthesis, suggested that acupuncture effectively regulates OAB symptoms including urgency, frequency and voiding dysfunction.1
A 2023 systematic review in Frontiers in Neurology discussed the possible mechanism: Acupuncture suppresses uninhibited bladder contractions by modulating motor neurons in the brainstem that govern urogenital activity, passing information via sensory ganglia through the spinal cord.2 This is neuromodulation. It operates through the same neural pathways our sacral foramina points were reaching long before we had the imaging to see it.
For stress urinary incontinence, a 2025 meta-analysis in Frontiers in Medicine found that both electroacupuncture and manual acupuncture significantly reduced urine leakage and improved quality of life on the ICIQ-SF.3 Acupuncture combined with pelvic floor muscle training outperformed pelvic floor muscle training alone. Acupuncture as monotherapy outperformed sham. The pelvic floor responds to the needle.
Chronic Pelvic Pain: Chronic pelvic pain is one of the conditions most likely to arrive in our practices without a name. Clients describe it as pressure, heaviness, a general wrongness they have stopped mentioning because no one has known what to do with it.
A 2023 meta-analysis in Healthcare evaluated 17 RCTs encompassing 1,455 patients and found acupuncture monotherapy demonstrated higher treatment efficacy than Western medication, TCM medication, physiotherapy, health education, and sham acupuncture.4 Not equivalent to conventional options – acupuncture is superior to them.
A 2024 systematic review and meta-analysis in PLoS One found that acupuncture, used alone or alongside routine care, produced significantly greater abdominal pain relief in pelvic inflammatory disease than routine care alone.5
Endometriosis and Dyspareunia: Endometriosis affects an estimated 10 to 15% of women of reproductive age. It causes dysmenorrhea, chronic pelvic pain, dyspareunia, and infertility, and there is no conventional cure.6 These are patients who have often been told their pain is normal. That surgery is the only option. That intimacy is going to hurt and that is simply how it is. It is not simply how it is.
A 2024 systematic review and meta-analysis found acupuncture significantly reduced endometriosis-related pain on VAS/NRS (SMD = 1.10, p < 0.001), improved clinical response rates and decreased serum CA-125, a biomarker of endometrial tissue activity.6 A 2025 meta-analysis of nine RCTs confirmed acupuncture as monotherapy significantly reduced pain scores compared to non-acupuncture interventions (mean difference = 1.67, p = .006) with improved clinical response rates.7
On dyspareunia specifically, a 2024 study on deep infiltrating endometriosis found the percentage of women with moderate to severe disability from painful intercourse dropped from 73.3% to 36.9% over a structured course of treatment.8 Acupuncture changed their experience of their bodies. It changed their intimate lives.
How Acupuncture Reaches the Pelvic Floor
The research tells us what is happening. The mechanisms tell us how.
Neuromodulation is the most consistently documented pathway. Electroacupuncture at the sacral foramina, particularly UB 32 through 34, directly stimulates sacral nerve segments and inhibits pain at the segmental spinal cord level. The sacral nerve roots innervate the pelvic floor, external urethral sphincter, external anal sphincter, posterior hip rotators and the sensory fields of the perineum, genitals and posterior thigh.9
When we needle the sacral foramina with electroacupuncture, we are not approximating the nerve. We are at the nerve.
Anti-inflammatory and circulatory effects operate through a second pathway. Acupuncture modulates chronic pelvic pain through neuroimmune regulation, reducing inflammatory mediators, improving local blood flow and restoring pelvic floor muscle tone.4 The tissues of the pelvic floor, like all musculoskeletal tissue, are exquisitely responsive to changes in circulation and neurochemical environment. Acupuncture creates those changes.
Pelvic floor muscle regulation itself is the third pathway. Both electroacupuncture and manual acupuncture have demonstrable effects on pelvic floor muscle tone and recruitment, the same tissue that houses CV 1 and GV 1, the same tissue that our classical texts were directing us toward for millennia.
Case Closed
As acupuncturists, we are asked regularly to consider whether a particular condition or population falls within our scope. The answer, for pelvic health, is not a matter of interpretation or expansion. It is a matter of returning to what the tradition has always held.
Our channels were mapped through the pelvis with precision. Our most foundational extraordinary vessels originate and converge there. We have classical points documented in the pelvic floor tissue itself, with clinical indications spanning the full range of conditions that modern research is now confirming we can effectively treat. We have a growing body of RCTs and meta-analyses demonstrating efficacy in overactive bladder, stress urinary incontinence, chronic pelvic pain, endometriosis, dyspareunia and fertility support. We have mechanisms that explain how the needle reaches the tissue and what it does when it arrives.
Acupuncturists who treat pelvic health are not approximating care with nearby points. We are working a territory that was mapped for us by our predecessors, documented in our classics and increasingly confirmed by the research Western medicine colleagues are beginning to pay attention to.
The question is not whether the pelvic floor is in our scope. It is and it always has been. The question is whether we have given ourselves the clinical training to meet what has always been ours to treat. Patients are waiting. The gap is ours to close.

Fertility acupuncture sometimes gets presented as a narrow protocol: a handful of reproductive points applied uniformly across patients. What this case reinforced for me: The most powerful work happens when we read the whole picture. The hormone data, the constitutional tendency, the sleep, the digestion, and the menstrual pattern, so we can treat the environment the ovaries live inside.
Mast cell activation syndrome (MCAS) affects more than 15% of the U.S. population but evades most practitioners’ radar. Just five years ago, it wasn’t even on my radar, despite already having 20 years of experience as a clinician at that time. The more I dug (similar to leaky gut and post-COVID syndrome), the more I found my patients were suffering from this disorder.
The motivation behind our practice of medicine is important, impacting not just our experience but also the experiences of those we treat. It is perhaps for this reason that the aspiration to help not just some, but all beings heal, has historically been an important part of the medical tradition. To explain this, we need to consider how medicine is interwoven with other social domains.
