Chances of Getting Pregnant with One Fallopian Tube
For many women trying to conceive, learning they have only one functioning fallopian tube can raise serious concerns about fertility. Whether due to surgery, ectopic pregnancy, or a congenital issue, the absence or damage of one fallopian tube might seem like a barrier to motherhood. However, it's important to know that getting pregnant with one fallopian tube is entirely possible—and quite common in many cases.
This article will explore the chances of conceiving with a single fallopian tube, what factors influence fertility, and what steps can be taken to improve outcomes for women in this situation.
Understanding the Role of Fallopian Tubes in Fertility
Fallopian tubes are essential reproductive organs that connect the ovaries to the uterus. Their primary role is to:
- Pick up the egg after ovulation
- Serve as the site for fertilisation by sperm
- Transport the fertilised egg to the uterus for implantation
If one tube is missing or blocked, the ovulated egg from the ovary on that side has no direct path to meet sperm. But that doesn’t mean conception is impossible. The body is often more adaptive than we realise.
Can You Still Get Pregnant with One Fallopian Tube?
Yes. Women with one healthy and functioning fallopian tube can still conceive naturally, provided other fertility conditions are favourable. In many cases, the remaining tube can compensate for the missing one, capturing eggs from either ovary.
For example, if a woman ovulates from the ovary on the side without the tube, the egg can sometimes still be picked up by the opposite fallopian tube. This process, called transperitoneal migration, is not guaranteed but has been documented in numerous cases.
Common Reasons for Having One Fallopian Tube
- Ectopic pregnancy: A fertilised egg implants outside the uterus, often in the tube, requiring surgical removal
- Tubal ligation reversal: A sterilisation procedure where tubes are cut or blocked, and only one is restored later
- Pelvic infections: Infections such as PID (pelvic inflammatory disease) can damage one or both tubes
- Congenital absence: Some women are born with one fallopian tube
- Endometriosis or fibroids: These may require surgical removal of one tube
Factors That Influence Fertility with One Tube
1. Condition of the Remaining Tube
The most critical factor is the health and functionality of the remaining tube. If it’s open, free from scar tissue, and capable of picking up an egg, chances of natural conception remain strong.
2. Ovulation Patterns
Ovulation typically alternates between ovaries each month, but it’s not always predictable. If ovulation occurs on the side without a tube, conception may be less likely that month unless transperitoneal migration occurs.
3. Age
As with all fertility concerns, age plays a significant role. Women under 35 with one tube and no other fertility issues often have good chances of conceiving naturally. Fertility begins to decline more sharply after 35.
4. Sperm Quality
Fertility is a two-person journey. Sperm count, motility, and morphology also affect the chances of successful fertilisation.
5. Underlying Conditions
Conditions like endometriosis, PCOS, or uterine abnormalities can compound fertility challenges. Comprehensive testing can help diagnose these issues early.
Medical Evaluation and Diagnosis
If you've had surgery, infections, or suspect damage to your reproductive organs, a fertility specialist may recommend the following tests:
- Hysterosalpingography (HSG): A type of X-ray that shows whether your remaining fallopian tube is open
- Ultrasound scans: To monitor ovulation and assess the uterus and ovaries
- Laparoscopy: A minimally invasive surgery to visually inspect the reproductive organs
- Hormonal tests: To assess ovulation, egg reserve, and thyroid function
Chances of Natural Conception
Studies suggest that women with one healthy fallopian tube and normal ovulation have a 60–80% chance of conceiving naturally within a year. This is comparable to women with two tubes, assuming no other fertility issues are present.
However, time and age are critical. If you’ve been trying for 6–12 months without success, especially if you’re over 35, it’s worth consulting a fertility specialist.
When to Consider Fertility Treatments
1. Ovulation Induction
Medications like Clomid or Letrozole can stimulate ovulation and may improve the chances of conception if ovulation is inconsistent.
2. Intrauterine Insemination (IUI)
Sperm is inserted directly into the uterus, timed with ovulation. This increases the chance that sperm will meet the egg near the healthy tube.
3. In Vitro Fertilisation (IVF)
IVF bypasses the fallopian tubes entirely. Eggs are retrieved, fertilised in a lab, and transferred to the uterus. IVF is particularly useful if:
- The remaining tube is blocked or damaged
- Other factors like endometriosis or low sperm count exist
- The woman is over 38 and has been trying unsuccessfully
Tips to Boost Fertility Naturally
- Track ovulation using basal body temperature or ovulation predictor kits
- Maintain a healthy weight and balanced diet
- Avoid smoking, alcohol, and excess caffeine
- Take prenatal vitamins with folic acid
- Manage stress with yoga, mindfulness, or therapy
- Have regular, unprotected sex during your fertile window
Success Stories and Hope
Case Study: “After an ectopic pregnancy and losing one fallopian tube, I thought my dream of motherhood was over. My doctor reassured me that I still had a strong chance. With tracking and patience, I conceived naturally within 9 months.” – Emily, 33
Thousands of women around the world have had successful pregnancies with one tube. With the right medical advice, emotional support, and patience, the journey to parenthood remains within reach.

FAQs About Pregnancy with One Fallopian Tube
Can I get pregnant naturally with one fallopian tube?
Yes, if the remaining tube is healthy and you're ovulating regularly, natural conception is very possible.
Does ovulation always alternate between ovaries?
Not always. Ovulation can be random or favour one side. Tracking ovulation helps identify your pattern.
What are the signs of a blocked fallopian tube?
Often there are no symptoms. An HSG test or laparoscopy is needed to confirm blockage.
Should I try naturally or go straight to IVF?
If you're under 35 with no other issues, try naturally for 6–12 months. After that, consult a fertility specialist.
Is one fallopian tube enough to have multiple children?
Absolutely. Many women with one tube go on to have more than one child with or without assistance.
