In order to achieve a pregnancy, the egg has to be fertilised by the sperm. Fertilisation is the fusion of an egg and a sperm to form an embryo. Fertilisation can occur in-vivo (inside body such as conceiving by natural means) or in-vitro (outside the body). Fertilisation that occurs outside the body is known as in-vitro fertilisation.
The most common fertility treatments are:
- Intracytoplasmic sperm injection (ICSI) in In-vitro Fertilisation (IVF) treatment
- Intrauterine Insemination (IUI) treatment
