Getting Pregnant with a Blocked Fallopian Tube

By Dr (TCM) Attilio D'Alberto | Traditional Chinese Medicine Practitioner, Wokingham

Being told that one of your fallopian tubes is blocked is an unsettling result, but it does not mean you cannot conceive naturally. Provided the other tube is patent and functioning, ovulation is occurring, and there are no other significant fertility issues, natural conception is realistic — published data suggest natural conception rates of around 50% of normal within six to twelve months of trying. The question is whether the blockage has a treatable cause, whether the open tube is fully functional (not just patent), and how to optimise everything else in the conception equation. Traditional Chinese medicine has been used for tubal disorders for centuries, and modern research now supports its role in pelvic inflammation, blood stasis, and adhesion-related infertility.

How the fallopian tubes work

The fallopian tubes are two thin, muscular tubes about 10 cm long, running from the upper outer corners of the uterus to the ovaries. Each month, the fimbriae at the ovarian end of the tube sweep over the ovary at ovulation and pick up the released egg. The tube then transports the egg towards the uterus, while sperm travel up from below. Fertilisation normally happens in the outer (ampullary) third of the tube, and the resulting embryo is gently moved by ciliated cells and muscular contractions back to the uterus over the next 5-7 days. If the tube is blocked, scarred or damaged, any of these steps can fail.

What causes tubal blockage?

The most common causes I see in clinic include:

• Pelvic inflammatory disease (PID) — usually following untreated chlamydia or gonorrhoea infection. The leading global cause of tubal damage.
• Endometriosis — endometrial tissue and adhesions distort and seal the tubes, even when the tubes themselves are not directly infiltrated.
• Previous abdominal or pelvic surgery — appendicectomy with peritonitis, ovarian cyst surgery, ectopic pregnancy surgery, or caesarean section can leave adhesions.
• Hydrosalpinx — fluid-filled, dilated and blocked tube, often the long-term outcome of past PID. The fluid is toxic to embryos and reduces IVF success.
• Previous ectopic pregnancy — even when the tube is preserved, scarring is common.
• Tubal ligation — surgical sterilisation; not all reversal attempts succeed.
• Congenital abnormalities — rare; one tube absent or malformed from birth.

How tubal blockage is diagnosed

Tubal patency is usually assessed in one of three ways:

• HyCoSy (hysterosalpingo-contrast sonography) — outpatient ultrasound with foam contrast through the cervix. Often the first-line test.
• HSG (hysterosalpingogram) — X-ray with iodinated contrast. Has a small but real "flushing" effect, with a few months of slightly improved fertility afterwards.
• Laparoscopy with dye test — gold-standard surgical assessment, used when imaging is inconclusive or other pelvic pathology (endometriosis, adhesions) is suspected. Allows treatment at the same time.

It is important to understand that "patent" is not the same as "fully functional". A tube can be open to dye but have lost its ciliated lining or muscular co-ordination from past inflammation, which is why some women with one or both tubes "open" still struggle to conceive.

Chances of natural conception with one blocked tube

Several factors determine the realistic chance of natural pregnancy:

• Which tube is blocked — the body does not always ovulate from the side with the patent tube each month, but the patent tube can usually pick up an egg from the contralateral ovary.
• Cause of the blockage — adhesions and PID often affect both tubes to some degree, even if only one is fully blocked.
• Age and ovarian reserve — over 35 or with low AMH, time matters more.
• Sperm quality — half the equation; always test before assuming the tubes are the limiting factor.
• Other pelvic factors — endometriosis, fibroids, ovulation disorders.

Most fertility guidelines suggest 6-12 months of trying with one patent tube before escalating to assisted conception in younger women, and 6 months in women over 35.

TCM patterns behind tubal blockage

Chinese medicine sees tubal disease as obstruction of the uterine collaterals. The main patterns are:

• Blood stasis — the dominant pattern. Old, congealed blood and adhesions block the channels. Signs: fixed sharp period pain, dark clotted flow, purple tongue.
• Phlegm-dampness — common in hydrosalpinx and post-PID inflammation. Signs: heavy discharge, weight around the middle, oily skin, sluggish digestion.
• Damp-heat in the lower jiao — the residue of past pelvic infection. Signs: yellow discharge, urinary symptoms, lower abdominal heaviness.
• Cold in the uterus — particularly in women with painful periods relieved by warmth. Cold causes blood to congeal and tubes to constrict.
• Kidney deficiency — the underlying terrain in many cases, especially with low AMH.

How acupuncture supports tubal fertility

Acupuncture works on tubal-related infertility through several documented mechanisms:

• Improved pelvic blood flow — Doppler studies show reduced uterine artery resistance after acupuncture, improving the inflammatory environment around the tubes.
• Anti-inflammatory effects — reduction of pelvic inflammatory markers; relevant in PID-related and endometriosis-related tubal disease.
• Improved endometrial receptivity — even when tubes are the issue, optimising the implantation environment helps when fertilisation does occur.
• Stress and HPO-axis modulation — better cycle regularity and ovulation, which matters when only one ovulation per month leads to a usable egg.

Typical treatment is weekly for three months, with extra sessions around ovulation if natural conception is the goal. Core points include CV 4, CV 6, ST 29, SP 6, SP 8, LR 3 and LI 4, with extras for the dominant pattern.

Chinese herbal medicine and pelvic circulation

A 2014 systematic review in the journal Evidence-Based Complementary and Alternative Medicine found that Chinese herbal medicine, particularly when combined with external herbal application or retention enemas, improved tubal patency in women with mild to moderate obstruction. Common base formulas:

• Gui Zhi Fu Ling Wan — moves blood and resolves masses; the workhorse formula for fibroids, endometriomas and adhesions.
• Ge Xia Zhu Yu Tang — strong blood-moving formula for fixed lower abdominal masses.
• Modified Shao Fu Zhu Yu Tang — for cold and blood stasis in the lower abdomen.
• Wen Jing Tang — warms the channels and moves blood; helpful where cold and deficiency coexist.

Key herbs include Dan Shen (salvia), Dang Gui, Tao Ren, Hong Hua and Yi Mu Cao for blood-moving; Fu Ling and Cang Zhu for damp; Bai Hua She She Cao and Lian Qiao if heat is present. I prescribe pharmaceutical-grade granules from Sun Ten in Taiwan, tailored to pattern and reviewed monthly.

Diet and lifestyle for tubal health

• Anti-inflammatory diet — reduce refined sugar, vegetable oils and alcohol; build meals around oily fish, vegetables, olive oil and whole grains.
• Quit smoking — tobacco directly damages tubal cilia and accelerates ovarian ageing.
• Maintain healthy weight — obesity worsens systemic inflammation and pelvic congestion; very low body weight suppresses ovulation.
• Castor oil packs — applied warm to the lower abdomen, three to four times per week between menstruation and ovulation; widely used in fertility traditions to improve pelvic circulation.
• Treat any current infection — get a full STI screen if not already done; persistent low-grade infection sustains inflammation.
• Self moxibustion — over CV 4, CV 6 and ST 29 between period and ovulation can warm the lower abdomen and improve circulation in cold/stasis patterns.

Timing intercourse and tracking ovulation

With one tube blocked, every ovulation matters. Maximise your chances by:

• Tracking ovulation with basal body temperature, OPK strips, or fertility apps.
• Aiming for intercourse every 1-2 days from cycle day 10 through ovulation, regardless of which side you suspect is ovulating — the patent tube can often pick up eggs from the contralateral ovary.
• Optimising sperm quality: full semen analysis, three months of preconception care, and reasonable lifestyle (alcohol, heat, smoking).

When IVF is the better option

IVF bypasses the tubes entirely and is the right choice when:

• Both tubes are blocked.
• One tube has hydrosalpinx — the toxic fluid significantly reduces IVF success unless the tube is removed or clipped first (salpingectomy or proximal occlusion).
• Significant adhesions or severe endometriosis are present.
• Male factor or low ovarian reserve also coexist.
• Six to twelve months of natural trying with one patent tube has not succeeded.

Even when IVF is the chosen route, three to four months of acupuncture and Chinese herbal medicine before the cycle improves egg quality, endometrial thickness, and uterine receptivity — see my pages on acupuncture for IVF.

Frequently asked questions

Can one fallopian tube get me pregnant?

Yes. As long as the remaining tube is patent and functional, ovulation is occurring, and sperm parameters are reasonable, natural conception is achievable. Published data suggest about 50% of normal natural conception rate over 6-12 months.

Does it matter which side ovulates each month?

Less than people assume. The patent fallopian tube can usually retrieve an egg from the contralateral ovary by sweeping across the pelvis, which is why women with one tube and the opposite ovary still conceive. Aim for intercourse around every ovulation, not just the "good" side.

Can acupuncture and Chinese herbs unblock a fallopian tube?

For mild to moderate inflammatory adhesions, yes — published Chinese trials show improved tubal patency on follow-up imaging after combined oral and external herbal treatment. For dense scarring after severe PID, hydrosalpinx, or surgical occlusion, no — but TCM still optimises pelvic circulation, ovulation and the uterine environment for natural conception or IVF.

How long should I try naturally before considering IVF?

If you are under 35, 6-12 months of trying with one patent tube is reasonable. Over 35, escalate at six months. Over 40, or with low AMH, IVF is usually the more time-efficient option.

Should hydrosalpinx be removed before IVF?

Yes — current guidelines (NICE, ESHRE) recommend salpingectomy or proximal tubal occlusion before IVF in hydrosalpinx, because the toxic fluid otherwise reduces implantation rates by around 50%.

Can endometriosis be the reason for blocked tubes?

Yes. Endometriotic adhesions can encase or distort the tubes, and severe disease can occlude them outright. Combined surgical and TCM management is often needed.

Will an HSG itself improve my chances?

Yes, modestly. HSG with oil-based contrast has been shown to improve natural conception rates for several months afterwards (the "flushing effect"). It is not a treatment in its own right, but the timing window after the test is a useful trying period.
