Causes
Blocked tubes and unexplained infertility
When the cause is a blockage, or is not found.
The fallopian tubes carry the egg to meet the sperm. Infection, endometriosis or previous surgery can block them, so they are checked with an X-ray dye test (HSG) or an ultrasound test. When every test is normal, infertility is called unexplained. This is common, and treatment still works.
- IVF bypasses blocked tubes
- A swollen, fluid-filled tube (hydrosalpinx) may be treated before IVF
- Unexplained infertility often responds to ovulation induction with IUI
- IVF is offered if simpler treatment has not worked
