Intratubal insemination is a medical procedure that involves the injection of sperm into the woman's fallopian tubes. However, there are a few synonyms for intratubal insemination that are commonly used in the medical field. One of them is fallopian tube sperm perfusion, which is a technique where sperm is delivered to the tubes through a catheter. Another term used is tubal embryo transfer, which is a procedure where an already fertilized egg is transferred to the fallopian tubes. Finally, tubal flushing is another term used to describe intratubal insemination, which involves flushing the fallopian tubes with a special fluid to increase the chances of fertilization. Regardless of what term is used, the goal of these procedures is to increase the chances of pregnancy in women who have difficulty conceiving naturally.
