In vitro fertilisation

In vitro fertilisation (IVF) is a technique in which egg cells are fertilized outside the woman's body. IVF is a major treatment in infertility where other methods of achieving conception have failed.

Developments

Intracytoplasmic sperm injection (ICSI) is a more recent development associated with IVF which allows the sperm to be directly injected in to the egg using micromanipulation.

This is used for sperm that have difficulty penetrating the egg and when sperm numbers are very low. ICSI results in success rates equal to IVF fertilization.
