In Vitro Fertilisation (IVF)
- In vitro fertilization (IVF) involves combining an egg with sperm in a laboratory.
- The term "vitro" is Latin for glass, referring to the laboratory glassware used.
- IVF steps:
- Administering follicle stimulating hormone (FSH) and luteinizing hormone (LH) to stimulate egg maturation.
- Collecting mature eggs from the mother using a long needle.
- Fertilizing the eggs with sperm in the lab to form embryos.
- Inserting one or two embryos into the mother's uterus using a needle.
- The sperm used can be from the father or a sperm donor.
- Advances in microscopy have enhanced IVF by improving the ability to see and assess the health of cells.
- IVF enables various family formations, including surrogacy and reciprocal IVF, popular in female same-sex relationships where one partner donates an egg and the other carries the pregnancy.
