How could somebody still have children if they have blocked fallopian tubes?

IVF. In vitro fertilization. That is a treatment where the eggs are removed from the ovary and the sperm is placed inside the eggs. The the early pregnancy (embryo) is placed inside the uterus. In other words, everything that is normally done inside the fallopian tube is now done without relying on the tube.
IVF. Ivf is the best choice for a woman with healthy eggs, sperm, and uterus, but blocked fallopian tubes. Surgery is an option to consider. Testing and effective treatment are available.
