Revise: Reproductive technologiesIn vitro fertilisation (IVF) is another reproductive technology. It can be useful when fertilisation is unlikely to happen naturally, for example if the oviducts are blocked or there is a sperm problem. FSH and LH are given to stimulate several eggs to mature and become ready for collection, rather than relying on the single egg usually released in a cycle.
