Prevention of fertilisation

Explanation:
The main idea here is preventing the meeting of sperm and egg. Contraception is the term for methods that stop fertilisation from happening. It includes barriers that block sperm from reaching the egg and hormonal approaches that stop ovulation or make fertilisation unlikely. Fertilisation is the actual fusion of sperm and egg, so it describes what happens if fertilisation isn’t prevented. Ovulation is simply the release of the egg, which is a precondition for fertilisation but not itself about prevention. Gestation refers to the development of a fertilised egg into a fetus, which occurs after fertilisation. So contraception best fits the concept of preventing fertilisation.
