What Causes Blocked Fallopian Tubes NHS?

Fallopian Tubes

Blocked fallopian tubes, a condition known as tubal factor infertility, can result from various causes. The National Health Service (NHS) in the United Kingdom recognizes several factors that may contribute to blocked fallopian tubes. Some common causes include:

  • Pelvic Inflammatory Disease (PID): Infections, usually sexually transmitted infections (STIs) like chlamydia or gonorrhea, can cause inflammation and scarring of the fallopian tubes, leading to blockages. PID is a significant risk factor for tubal factor infertility.
  • Endometriosis: Endometriosis is a condition where tissue similar to the lining of the uterus grows outside the uterus. If endometriosis involves the fallopian tubes, it can lead to adhesions and blockages.
  • Previous Abdominal or Pelvic Surgery: Surgeries, such as those for ectopic pregnancies, ovarian cysts, or other conditions, can result in scar tissue formation that may block the fallopian tubes.
  • Tubal Ligation: Surgical procedures for permanent contraception, such as tubal ligation (having one’s tubes tied), can lead to intentional blockage of the fallopian tubes.
  • Hydrosalpinx: This is a condition where the fallopian tube is blocked and filled with fluid, often as a result of an infection or inflammation. It can affect fertility by preventing the egg and sperm from meeting.
  • Congenital Abnormalities: Some individuals may have congenital (present from birth) abnormalities in the structure of the fallopian tubes that can contribute to blockages.
  • Prior Ectopic Pregnancy: An ectopic pregnancy occurs when a fertilized egg implants outside the uterus, often in a fallopian tube. This can cause damage to the tube and lead to blockages.

It’s important to note that blocked fallopian tubes can be asymptomatic, meaning there may be no noticeable signs or symptoms. Some individuals may only discover the blockage when experiencing difficulty getting pregnant.

If a woman is having trouble conceiving and blocked fallopian tubes are suspected, healthcare professionals may recommend tests such as hysterosalpingography (HSG), laparoscopy, or hysteroscopy to assess the condition of the fallopian tubes. Treatment options may include surgery to repair or unblock the tubes, or in some cases, assisted reproductive technologies (ART) like in vitro fertilization (IVF) may be recommended.

If you have concerns about fertility or suspect blocked fallopian tubes, it’s advisable to consult with a healthcare professional or a fertility specialist for a thorough evaluation and personalized guidance.
