Henggu

What is KI11?

KI11 (Henggu) is a Kidney-channel point on the lower abdomen, just beside the midline at the top edge of the pubic bone.

Its pinyin name, Henggu, means "pubic bone" and simply describes where it sits. It is the first point of the Kidney channel's abdominal section, and classical texts group it with the nearby points used for bladder and genital complaints.

In traditional Chinese medicine, KI11 is described as a place to work on the lower burner — the lower abdomen and pelvis in that system's map of the body. Traditional indications include difficulty passing urine, dribbling, genital pain, loss of sexual function, seminal emission and lower abdominal fullness. These are tradition's categories, not modern diagnoses, and they do not translate neatly into them.

Two things are worth saying once, clearly, before the rest of the page. First, the fact that a point has been taught for centuries is not evidence that pressing it does anything; long use and proven effect are different claims. Second, long use is not evidence that it is safe either, and KI11 sits over the bladder and lower bowel, which makes that point more than theoretical here.

The honest verdict on the evidence: there is essentially no human research testing KI11 specifically, by finger pressure or otherwise. Acupressure research as a whole is dominated by small, short, unblinded studies, and KI11 is not one of the points that has been studied even at that level. What you can reasonably expect from it is a warm, calming, self-soothing few minutes of gentle abdominal pressure — which some people genuinely find settling — and nothing that has been demonstrated beyond that.

Everything on this page is self-applied finger pressure on your own body. We do not describe needling, moxibustion or cupping, and you should not attempt them on yourself. Where a study needled a point, we say so, because that is what the study did.

Where is KI11 and how do you find it?

KI11 sits at the upper edge of the pubic bone, about half a thumb-width out to one side of the body's midline.

• Lie down first. Lie on your back with your knees bent and feet flat. This lets the lower abdominal muscles go soft, so you can feel bone instead of tense muscle.
• Find your navel. Put one fingertip in your belly button. This is the top of the measuring line you will use.
• Find the top of the pubic bone. Slide your fingers straight down the midline from the navel until you meet a firm, horizontal bony ridge low in the abdomen. That ridge is the upper border of the pubic symphysis — the joint at the front of the pelvis.
• Check the distance. In traditional measurement, navel to pubic bone is five cun, and KI11 sits at the bottom of that line. On most adults that is roughly 12 to 15 cm below the navel, but the bony ridge is the reliable landmark, not the number.
• Step off the midline. From the midline point on that bony edge, move about half a thumb-width — roughly 1 cm — to one side. That soft spot, right where the tissue meets the top of the bone, is KI11. There is one on each side.

The midline reference you are stepping away from is the Conception Vessel point CV2; KI11 is the pair of points just lateral to it. If you cannot tell whether you are on the bone or just above it, stay on the soft tissue at the upper border. Pressing directly onto the hard bone is uncomfortable and achieves nothing.

Body hair, scars and body shape all change how obvious the ridge feels. Take your time, use flat finger pads rather than nails, and stop hunting if the area is tender for reasons you have not had checked. Never use any sharp or skin-breaking tool here.

How do you apply pressure to KI11?

1. Empty your bladder first. KI11 lies directly over the bladder region. Pressing a full bladder is uncomfortable and can make you feel an urgent need to urinate.
2. Get comfortable and warm. Lie on your back with knees bent, in privacy, with warm hands. Cold fingers on the lower abdomen make the muscles tighten and guard.
3. Place flat finger pads. Use the pad of your index or middle finger on each side, or one hand at a time. No nails, no knuckles, no tools.
4. Press gently straight down. Sink slowly toward the top edge of the pubic bone. Aim for a firm but easy sensation — about three or four out of ten. The lower abdomen is soft tissue over organs, so this is not a place for deep digging.
5. Hold or circle. Either hold steady for 30 to 60 seconds, or make small slow circles for one to two minutes. Breathe out as you press in and let the belly soften.
6. Do both sides. KI11 is a paired point. Work one side, then the other, or both together with two fingers.
7. Repeat sparingly. One to three short sessions a day is plenty. There is no benefit to longer or harder.

Stop immediately and do not continue if you feel sharp or stabbing pain, a bulge that appears under your fingers, burning when you urinate, fever, or pain that spreads to your back or groin. Stop too if the area simply feels wrong or raw.

Keep total time short. Five minutes across the whole session is more than enough, and the lower abdomen can feel bruised and sore the next day if you overdo it. If you are not sure whether pressure here is sensible for you — because of pregnancy, recent surgery, a hernia or an unexplained lump — do not press and ask a clinician instead.

What is KI11 traditionally used for?

• Urinary complaints. Classical texts list KI11 for difficulty passing urine, dribbling and retention. No human trial has tested finger pressure on KI11 for any urinary problem, so this remains a traditional indication only. Urinary retention is a medical emergency and is not a self-care situation.
• Sexual and reproductive symptoms. Tradition names impotence, seminal emission and infertility among KI11's uses, because the Kidney channel is linked in that system to reproduction. There is no controlled human evidence that pressing KI11 affects erectile function, sperm, or fertility of any kind.
• Period pain. KI11 is sometimes added to lower abdominal routines for painful periods. Small trials of acupressure for period pain exist, but they overwhelmingly use SP6 on the inner ankle, not KI11, so they cannot be used to support this point.
• Lower abdominal fullness and hernia-type pain. Old texts describe KI11 for shan disorders — a broad traditional category covering groin and lower abdominal pain, including what we would now call hernia. A hernia is a structural problem that needs assessment, and pressing on a bulge is not safe.
• Pelvic tension and self-soothing. The clearest honest use is also the most modest. Slow, warm, light pressure on a relaxed lower abdomen with steady breathing can feel calming. That effect belongs to the warmth, the breathing and the attention as much as to the specific point.

The overall picture is a well-described traditional point with no specific human evidence behind it. Acupressure studies in general are small, short and unblinded, which makes it hard to separate a real effect from expectation and from the relaxing act of lying down. For KI11 the gap is bigger than that: the studies simply have not been done.

Treat KI11 as a comfort measure you may add alongside proper care, never as a replacement for it.

Are there tips for using KI11 effectively?

• Go to the toilet first. An empty bladder makes KI11 far more comfortable to press and avoids a false sense of urgency that has nothing to do with the point.
• Let the belly soften. Knees bent, feet flat, a pillow under the head. A guarded, braced abdomen hides the bony landmark and makes every touch feel sharper than it is.
• Warm the area first. A warm palm resting over the lower abdomen for a minute, or a covered warm pack, helps you relax before any pressure. Never use anything hot enough to redden the skin.
• Breathe out as you press. Sink on the out-breath and ease off on the in-breath. Much of what people enjoy about abdominal points comes from the slow breathing that goes with them.
• Go lighter than you think. This is thin tissue over bone on one side and organs on the other. Firm and comfortable beats deep and determined every time.
• Work both sides. KI11 is paired. Giving each side the same short time keeps the session balanced and stops one side getting sore.
• Keep sessions short and regular. One or two minutes per side, once or twice a day, is more sustainable than a long session you do once.
• Only on yourself. This is an intimate area close to the genitals. Keep it as self-applied pressure, and never press here on another person, including a partner or child.
• Write down what happens. Note the day, what you did and how you felt. Symptoms that come and go on their own are easy to mistake for a response to pressure, and a simple log helps you see the difference.
• Pair it with care that works. Use KI11 alongside your prescribed treatment, pelvic floor physiotherapy, or whatever your clinician has advised — not instead of it.

What do people get wrong with KI11?

• Expecting a cure. KI11 is marketed online for impotence, infertility and bladder problems. No point cures these, and no acupressure routine has been shown to fix them. Expecting that leads people to delay care that could actually help.
• Pressing on the bone. Landing on the hard front of the pubic bone instead of the soft spot at its upper edge. It hurts, it bruises, and it is not the point.
• Drifting to the midline. Pressing exactly in the middle lands on CV2, not KI11. KI11 is the pair of points about half a thumb-width out on either side.
• Measuring from the wrong landmark. Counting finger-widths down from the navel without ever feeling for the bony ridge. The ridge is the reliable landmark; the distance varies with body size.
• Pressing with a full bladder. This turns a mild technique into an unpleasant one and tells you nothing useful.
• Digging deep. Using knuckles, thumbs or a tool to push hard into the lower abdomen. Harder is not better here, and the area can stay sore for a day or two.
• Pressing over a lump or bulge. A swelling in the groin or lower abdomen may be a hernia or something else that needs examining. Pressure is not the answer and may make things worse.
• Treating retention at home. Being unable to pass urine at all is an emergency, not a point to press. People have waited hours with a full bladder trying acupressure first.
• Ignoring pregnancy. Low abdominal pressure beside the pubic bone is not worth any uncertainty during pregnancy, however gentle.
• Using it on someone else. This point sits in an intimate area. Keep it self-applied only.

What does the research on KI11 actually say?

We found no useful human research testing KI11 specifically, by finger pressure or by any other method. No controlled trial, no named case series, and no reliable study of this point on its own. That is the honest answer, and inventing a citation to fill the gap would make this page worse.

That does not mean KI11 has been tested and failed. It means the question has not been asked properly. Many classical points have never been studied individually, because research usually tests whole treatment protocols rather than single points.

Some context helps. Acupuncture studies for lower urinary tract problems — such as urinary retention after surgery, overactive bladder and incontinence — do exist, and some report modest benefit. Those trials used needling by trained practitioners, and they typically used midline abdominal points, sacral points over the lower back, and SP6 on the inner leg. They did not isolate KI11, and needling results do not transfer to finger pressure, which is a different intervention on a different scale.

The same gap applies to the sexual and fertility claims attached to KI11 online. There is no controlled human evidence that pressing this point improves erectile function, sperm quality or chances of conception. Claims of that kind in videos and articles are tradition repeated with confidence, not findings.

Acupressure research in general shares well-known weaknesses. Study groups are small, participants know what they are getting, outcomes are self-reported, and follow-up is often only days or weeks. Lying still, breathing slowly and receiving attention produces real short-term improvement on symptom scores, which is hard to separate from the point itself.

Practically, this means you can try gentle KI11 pressure as a low-cost comfort measure if it is safe for you, while expecting little and keeping your actual medical care in place. If a symptom is new, worsening, or stopping you doing normal things, that is a reason to be assessed, not a reason to press harder.
