When couples face difficulties in conceiving, the cause can often be traced to a range of underlying health issues—one of which is damage to the fallopian tubes. Blocked or scarred fallopian tubes are a significant yet sometimes overlooked factor in female fertility problems.
Understanding the role of these delicate structures in reproduction, what can go wrong, and how this can be diagnosed and treated is essential for women hoping to conceive.
What Are Fallopian Tubes and Why Are They Important?
The fallopian tubes are slender, muscular ducts that connect the ovaries to the uterus. Their main role in female fertility is to transport the egg from the ovary to the uterus. Crucially, fertilisation of the egg by sperm usually takes place within the fallopian tube itself. Once fertilised, the embryo travels down the tube and into the uterus, where it can implant and develop into a pregnancy.
When the fallopian tubes are blocked, narrowed, or scarred, this journey is disrupted. This can prevent fertilisation altogether, or result in an ectopic pregnancy, where the embryo implants in the tube rather than the uterus—posing serious health risks.
Causes of Blocked or Scarred Fallopian Tubes
Several conditions can lead to blockage or scarring of the fallopian tubes, many of which are linked to pelvic inflammation or previous infections. Common causes include:
1. Pelvic Inflammatory Disease (PID)
PID is often caused by sexually transmitted infections such as chlamydia or gonorrhoea. If left untreated, the infection can cause inflammation and scarring of the fallopian tubes, reducing their ability to function properly.
2. Endometriosis
Endometriosis occurs when tissue similar to the uterine lining grows outside the womb. If this tissue forms on or near the fallopian tubes, it can cause inflammation, adhesions, and blockages. While endometriosis is primarily associated with pelvic pain and heavy periods, it is also a major contributor to reduced female fertility.
3. Previous Surgery
Operations involving the pelvis or abdomen—such as surgery for ovarian cysts, fibroids, or even appendicitis—can lead to the formation of scar tissue (adhesions), that affects the fallopian tubes.
4. Ectopic Pregnancy
If a previous pregnancy developed in the fallopian tube (an ectopic pregnancy), it could leave lasting damage. This can affect the integrity and patency of the tube, increasing the risk of future fertility issues.
5. Tubal Ligation or Sterilisation
Although typically a permanent form of contraception, some women who have undergone tubal ligation may later seek reversal. However, this procedure can leave the tubes partially blocked or scarred, affecting natural conception.
Diagnosing Blocked or Scarred Fallopian Tubes
A thorough female fertility diagnosis is essential to determine whether the fallopian tubes are contributing to infertility.
Several methods can be used to assess tubal health:
1. HYCOSY
Also known as saline infusion sonography, this test uses ultrasound imaging to observe the movement of saline fluid through the uterus and fallopian tubes. It is less invasive and avoids radiation exposure.
2. Hysterosalpingogram (HSG)
This is a specialised X-ray procedure in which a contrast dye is injected into the uterus and fallopian tubes. If the dye fails to pass through the tubes, a blockage may be present. It’s a quick, outpatient test commonly performed during fertility assessments
3. Laparoscopy
A more invasive but definitive diagnostic tool, laparoscopy involves inserting a small camera through the abdomen to visualise the reproductive organs. It is particularly useful when endometriosis or pelvic adhesions are suspected.
Treatment Options for Damaged Fallopian Tubes
Once a diagnosis confirms blocked or scarred fallopian tubes, treatment options will depend on the severity and underlying cause of the damage, as well as other factors such as age and overall health.
1. Surgical Treatment
In some cases, surgery may be able to repair damaged tubes. This is more likely to be successful in cases of mild scarring or blockages close to the uterus.
Procedures may include:
-
Tuboplasty (removal of scar tissue or reopening blocked segments)
-
Fimbrioplasty (reconstructing the finger-like ends of the tube)
-
Adhesiolysis (removing pelvic adhesions caused by conditions like endometriosis)
Success rates vary, and surgery carries risks such as further scarring or ectopic pregnancy. It’s not always the best option, particularly if both tubes are severely damaged.
2. In Vitro Fertilisation (IVF)
For many women with significant tubal damage, IVF is the most effective route to pregnancy. IVF bypasses the fallopian tubes entirely by retrieving eggs directly from the ovaries, fertilising them in a lab, and transferring the embryo into the uterus.
IVF is especially recommended when both tubes are blocked, when tubal surgery has failed, or when additional fertility factors such as PCOS (Polycystic Ovary Syndrome) or endometriosis are present.
3. Tubal Removal Before IVF
In some cases, particularly where the fallopian tubes are filled with fluid (a condition known as hydrosalpinx), doctors may recommend removing the affected tubes before undergoing IVF. This is because the fluid can leak into the uterus and interfere with embryo implantation, reducing the success rates of IVF treatment.
Managing Other Underlying Conditions
It's also crucial to manage any coexisting conditions that may be impacting fertility:
-
PCOS can cause irregular ovulation and may require medication to stimulate egg release.
-
Endometriosis may need hormonal treatment or surgery to improve the chance of conception.
A holistic fertility treatment plan often involves addressing these conditions alongside tubal issues.
Final Thoughts
Blocked or scarred fallopian tubes are a common and potentially serious barrier to conception.
Fortunately, advances in female fertility diagnosis and treatment now offer many women a pathway to successful pregnancy—even in the presence of tubal damage.
Early diagnosis is key, so if you’ve been trying to conceive for over a year (or six months if you’re over 35), reach out to us here at IVF Matters to start the process of diagnosis and treatment. By identifying the root cause—be it tubal issues, endometriosis, PCOS, or another factor—you can take informed steps towards achieving your goal of parenthood.
