In vitro fertilization
In vitro fertilization (or fertilization; IVF) is a type of assisted reproductive technology used for infertility treatment and gestational surrogacy in cases like: Blocked or damaged fallopian tubes; Male factor infertility including decreased sperm count or sperm motility. It is a process by which an egg is fertilized by sperm outside the body: in vitro ("in glass"). The process involves monitoring and stimulating a woman's ovulatory process, removing an ovum or ova (egg or eggs) from the woman's ovaries and letting sperm fertilize them in a liquid in a laboratory. The fertilised egg (zygote) is cultured for 2–6 days in a growth medium and is then transferred to the same or another woman's uterus, with the intention of establishing a successful pregnancy.
