Hydrosalpinx: What It Is, How It’s Diagnosed, and Its Impact on Fertility

Hydrosalpinx refers to a condition where one or both fallopian tubes become blocked and filled with fluid. This usually happens when the end of the tube near the ovary is sealed shut. As a result, fluid builds up inside the tube, causing it to swell.

In a healthy cycle, the fallopian tubes play a crucial role: they collect the egg from the ovary, facilitate fertilization, and transport the embryo to the uterus. When a tube is blocked by hydrosalpinx, this process is disrupted, making natural pregnancy difficult or impossible.

The most common cause is a previous infection or inflammation that damages the fallopian tubes. Over time, healing can lead to scarring, which can block the tube and trap fluid. Common hydrosalpinx reasons include:

• Sexually transmitted infections (STIs) such as chlamydia and gonorrhoea
• Pelvic inflammatory disease (PID)
• Endometriosis, which causes pelvic adhesions
• Previous pelvic or tubal surgery
• Severe abdominal infections, such as appendicitis

These conditions damage the delicate lining and fimbriae of the fallopian tubes, leading to blockage.

One of the biggest challenges with hydrosalpinx symptoms is that many people have none at all. The condition is often discovered during infertility testing. When symptoms do appear, they may include:

• Chronic or intermittent pelvic pain
• Pain that worsens during menstruation
• Unusual vaginal discharge

Hydrosalpinx discharge often looks watery, sticky, or slightly discolored, though not everyone experiences this symptom. In some cases, an ectopic pregnancy may be the first sign of tubal damage.

Accurate hydrosalpinx diagnosis requires imaging tests. Common diagnostic tools include:

• Hysterosalpingogram (HSG): A dye test that shows whether the tubes are open or blocked
• Hycosy: A test performed through a transvaginal scan using an echogenic foam that shows whether the tubes are open or blocked
• Pelvic ultrasound: A fluid-filled tube may appear enlarged and sausage-shaped
• Laparoscopy: A minimally invasive surgery that allows direct visual confirmation

HSG is most often the first test used to identify hydrosalpinx.

Hydrosalpinx can vary based on location and severity:

• Unilateral hydrosalpinx: One fallopian tube is affected
• Hydrosalpinx bilateral: Both fallopian tubes are blocked
• Mild vs severe: Based on the amount of fluid and the degree of tubal damage

Even small amounts of fluid can negatively impact fertility, especially during IVF cycles.

Hydrosalpinx and pregnancy are closely linked, as the condition significantly reduces fertility in several ways:

• Physical blockage prevents the sperm and egg from meeting.
• Toxic fluid inside the tube can damage sperm or embryos.
• Fluid may flow back into the uterus, interfering with implantation.
• Increased risk of miscarriage and ectopic pregnancy

Studies show that untreated hydrosalpinx can reduce IVF success rates by up to 50%.

While hydrosalpinx cannot be resolved on its own, medical and surgical treatments are effective. Common options include:

• Salpingectomy: Surgical removal of the affected tube (most effective before IVF)
• Salpingostomy: Opening and repairing the tube (higher ectopic risk)
• Aspiration or drainage: Temporary fluid removal (limited long-term benefit)

So, is hydrosalpinx treatable? Yes, hydrosalpinx is treatable, but treatment depends on fertility goals and tubal damage.

Hydrosalpinx treatment cost varies depending on:

• Type of procedure (laparoscopy vs open surgery)
• Hospital and geographic location
• Whether treatment is combined with IVF
• Insurance coverage

Your fertility specialist can provide guidance based on your individual situation.

Leaving a hydrosalpinx untreated can lead to permanent infertility and serious complications.

• Natural pregnancy is unlikely, especially if it is present bilateral
• IVF success rates are lower
• The risk of miscarriage doubles
• Ectopic pregnancy risk increases

IVF bypasses the fallopian tubes, making it the best option for many patients with hydrosalpinx. However, fluid within a damaged tube can still impair embryo implantation.

Medical evidence strongly supports removing the affected tube before IVF. This approach:

• Improves implantation rates
• Reduces miscarriage risk
• Does not harm ovarian reserve

For many patients, salpingectomy followed by IVF offers the highest chance of success.

You should consult a fertility specialist if:

• You have been trying to conceive for 12 months (6 months if over 35)
• You have chronic pelvic pain.
• You have a history of PID, STIs, or pelvic surgery.
