In Vitro Fertilization (IVF) is a medical procedure used to help individuals or couples conceive a child. It involves fertilizing an egg with sperm outside the body in a laboratory, and then transferring the resulting embryo into the uterus. IVF is commonly used to treat infertility caused by various factors, including blocked fallopian tubes, low sperm count, or unexplained infertility. It offers hope to many who struggle to conceive naturally, and has helped millions of families around the world.
