In Vitro Fertilization (IVF) is a fertility treatment where eggs and sperm are combined in a laboratory to create embryos, which are then carefully placed into the uterus to achieve pregnancy.

IVF is used when natural conception is difficult due to blocked tubes, low sperm count, PCOS, endometriosis, advanced age, or unexplained infertility.

Not always - many couples can conceive with simpler treatments such as lifestyle changes, fertility medications, or procedures like IUI, depending on the cause.
