Answer:
In vitro fertilization (IVF)
Explanation:
In vitro fertilization is conducted when infertility is perceived in sexual partners trying to have a baby. It is the process whereby matured ova/eggs are removed from the female's reproductive system and is fertilized externally in a laboratory (usually in a glassware) using a male's sperm cell. It can be thought of as a procedure where the normal fertilization process that occurs in a female's reproductive tract (fallopian tube) is carried out outside the body, specifically in a laboratory.
In order for this procedure to be employed, the male and female must be able to produce their respective gametes. The female's ovary is usually stimulated by fertility drugs in order to yield numerous eggs, which are then extracted from her ovary and fertilized by a sperm externally (in a laboratory). The resulting fertilized egg called embryo is placed back into the female's womb to carry it as a normal pregnancy.
