What is IVF (In Vitro Fertilisation)?

IVF is a fertility treatment in which eggs are collected from the ovaries and fertilised with sperm in a laboratory, with the resulting embryo (or embryos) transferred into the uterus. It's used to treat various causes of infertility, including blocked fallopian tubes, low sperm count, endometriosis, unexplained infertility, or when other treatments haven't worked.

A typical cycle involves hormone injections to stimulate the ovaries, egg collection, fertilisation in the lab, and embryo transfer, usually over several weeks. Success rates vary depending on factors like age and the underlying cause of infertility, and many people need more than one cycle.
