How does in vitro fertilization (IVF) differ from other assisted reproductive technologies, such as intrauterine insemination (IUI) or egg freezing, in terms of procedure, success rates, and potential outcomes for individuals or couples struggling with infertility?

IVF involves extracting eggs, fertilizing them in a lab, and implanting embryos into the uterus. IUI injects sperm directly into the uterus. IVF generally has higher success rates but is more invasive and costly.
In IVF, eggs are fertilized outside the body and embryos are transferred to the uterus, making it more complex and expensive than IUI, where sperm is simply inserted into the uterus. IVF tends to offer higher success rates.
IVF entails egg retrieval and in-lab fertilization before embryo transfer, unlike IUI which involves direct sperm insertion into the uterus, and egg freezing which preserves unfertilized eggs for future use. IVF typically shows higher success rates.
