Doctor suggested to get blocked fallopian tubes removed before IVF. Why?

Hey, that's not wrong. IVF does bypass the fallopian tubes, but the concern is usually hydrosalpinx--a blocked tube that's filled with fluid.

That fluid can leak into the uterus and create a less favorable environment for an embryo to implant. Multiple studies have found that women with untreated hydrosalpinx have lower implantation, pregnancy, and live birth rates with IVF. Removing the affected tube or blocking it before IVF has been shown to improve outcomes in these cases.

That said, not every blocked tube needs to be removed. If the tube is simply blocked but isn't swollen with fluid, the recommendation may be different. It's worth confirming with your doctor if they saw evidence of hydrosalpinx and why they believe surgery would improve your specific chances of success.
