Meaning
In Vitro Fertilisation is a fertility treatment in which the sperm and ovum are combined outside the body.
About In Vitro Fertilisation
In vitro fertilisation requires several steps.
- An ovary is injected with follicle stimulating hormone to cause several ova to mature.
- The ova are extracted from the ovary while a semen sample is provided by the male.
- The ova and sperm are mixed in a petri dish where the sperm fertilise the ova.
- The fertilised ovum is then inserted into the lining of the uterus for implantation.
