fertilization
Sperm joins egg
Fertilization is the union of male and female reproductive cells to form a new organism.
In animals, sperm fertilizes an egg; in plants, pollen fertilizes an ovule.
The term extends to enriching soil with nutrients: The lawn needs fertilization every spring.
In vitro fertilization (IVF) achieves conception outside the body.
