What is The Difference Between IVF and IUI?

IVF (in vitro fertilization) and IUI (intrauterine insemination) are two types of assisted reproductive technologies (ART) used to treat infertility. The main difference between the two procedures is where fertilization occurs.

In IUI, sperm is collected, prepared in a laboratory, and then inserted directly into the uterus through a catheter. This increases the chances of fertilization, as the sperm is placed directly into the fallopian tubes where it can potentially fertilize the egg. IUI is typically used when there are mild fertility problems, such as low sperm count, or when the cause of infertility is unknown.

In contrast, IVF involves removing eggs from a woman’s ovaries and fertilizing them with sperm in a laboratory dish. The resulting embryos are then transferred to the uterus, where they can implant and develop into a pregnancy. IVF is often used when there are more serious fertility issues, such as blocked fallopian tubes or severe male factor infertility.

While both IVF and IUI can be effective in helping couples conceive, IVF is typically more expensive and invasive than IUI. IVF also has a higher success rate per cycle, but it may require multiple cycles to achieve pregnancy. The choice between IVF and IUI depends on the specific fertility issues of the individual or couple and should be discussed with a fertility specialist.
