Conception

The start of pregnancy, when a fertilised egg implants in the womb lining.

Fertility basics

Conception covers the sequence in which sperm fertilises an egg, the resulting embryo travels down the fallopian tube and then attaches to the lining of the womb. In everyday use people say 'conception' to mean the moment of fertilisation, while clinically pregnancy is only established once implantation has occurred and hCG can be detected.

Also known as: falling pregnant, getting pregnant
