Tubal Factor Infertility
March 20, 2025- Tubal factor infertility involves any factor preventing a woman from becoming pregnant and completing the pregnancy until delivery. In fact, the occurrence of some obstruction in the fallopian tubes contributes to about 30-40% of female infertility cases. The role of the fallopian tubes is to conduct the egg from the ovary to the uterus for fertilization. Hence, when these tubes are blocked or injured, the sperm may not reach the egg, causing infertility.
- The degree of fertility impairment due to tubal factor infertility can be enormously high. When the fallopian tubes are unable to work, the chances of conceiving naturally fall alarmingly low.
- Understanding the causes of tubal factor infertility and the available treatments is important for enhancing the likelihood of a successful pregnancy.
What is Tubal Factor Infertility?
- Tubal factor infertility happens when the fallopian tube(s) obstruct sperm from getting towards the egg for fertilization or stop a fertilized egg (embryo) from getting to the uterus for pregnancy.
- If the fallopian tube is harmed, irregularly shaped, or obstructed, sperm and egg cannot meet, leading to infertility. On the other hand, if the tube is damaged but still permits fertilization to occur, the embryo may fail to reach the uterus and instead remain within the tube (ectopic or tubal pregnancy).
A blockage in the fallopian tube is categorized based on its location, which influences both the degree of obstruction and the approach to treatment.
- Proximal Tubal Blockage: This blockage is near the uterus and can happen due to tubal spasms, a mucus obstruction, or scarring in that area.
- Midsegment Tubal Blockage: This blockage is in the middle part of the fallopian tube. It is often caused by surgery to ligate the tubes or surgery to reverse that ligation.
- Distal Tubal Blockage: This blockage is at the end of the tube near the ovary, which can be partially or fully blocked. A blockage at this end often causes a build-up of harmful fluid known as hydrosalpinx.
Causes of Tubal Factor Infertility
The leading cause of fertility issues arising from tubal factors is infection. Other common causes that can block or scar the tubes include:
- Endometriosis is a condition where tissue typically found inside the uterus starts to develop outside of it.
- Pelvic inflammatory disease (PID) is an infection affecting the female reproductive system.
- Sexually transmitted infections (STIs), particularly chlamydia and gonorrhea.
- Ectopic pregnancy is a condition where the embryo implants outside of the uterus, typically in the fallopian tube.
Individuals are at a higher risk of experiencing infertility from fallopian tube complications if they have undergone abdominal surgery, including procedures for a ruptured appendix or ectopic pregnancies. Given the nature of these conditions, there is a greater probability of developing issues related to the fallopian tubes.
Treatment Options for Tubal Factor Infertility
Tubal factor infertility happens when the fallopian tubes are either blocked or injured, preventing the sperm's ability to reach the egg or stopping the fertilized egg from traveling to the uterus. However, multiple treatment options can assist couples in addressing tubal factor infertility. The treatment options are as follows:
Medication
- The first line of treatment for tubal factor infertility often involves medications. The goal of the treatment is to address any underlying issues, such as infections or inflammation, that may be contributing to this problem. Doctors often prescribe antibiotics to fight infections and anti-inflammatory medications to reduce swelling in the fallopian tubes.
Surgery
- Another potential solution for infertility resulting from fallopian tube problems is surgical intervention. The required surgical procedure is determined by the extent of the damage to the tubes and the specific location of that damage.
- If there is a minor obstruction or additional tissue in the tubes, physicians may opt for a minimally invasive approach known as laparoscopic surgery. In this surgery, the doctor uses a thin tube with a camera to see the tubes and remove any blockages.
- If the tubes are completely blocked or very damaged, a more complicated surgery called tubal ligation reversal or tubal reconstruction might be needed.
Assisted Reproductive Technologies (ART)
- Assisted reproductive technologies (ART) are special treatments that help couples who have trouble getting pregnant because of tubal factor infertility. The most common ART is in vitro fertilization (IVF).
- In IVF, doctors take eggs from a woman's ovaries and fertilize them with sperm in a lab to create embryos. These embryos are then placed in the woman's uterus. Since IVF doesn't use the fallopian tubes, it is an effective treatment option for couples with this type of infertility.
- There are other options, like intracytoplasmic sperm injection (ICSI) and gamete intrafallopian transfer (GIFT), which might be used based on the severity of the condition.
Bottom line
- Tubal factor infertility is becoming common, and examining the level and area of damage to the fallopian tubes will influence the treatment options suggested by our fertility expert. However, tubal surgery carries certain risks, such as the possibility of ectopic pregnancy, an increase in scar tissue in the reproductive area, and the risk of infection. Therefore, surgery might not always be the preferred option.
- If the damage is significant or there is a high chance of an ectopic pregnancy, our expert doctors at Apollo Fertility will probably suggest IVF instead of surgery. This treatment method for tubal factor infertility offers a promising chance of achieving success.
- Our expert doctors, gynecologists, and endocrinologists will assess the condition and help you guide throughout the treatment procedure. Book your appointment for an effective treatment approach!
