What is fertilization in animals?

Fertilization is preceded by copulation in which the erect penis is inserted into the vagina.
This leads to ejaculation of semen.
The sperms swim through the female’s genital tract to the upper part of the oviduct.
The head of the sperm penetrates the egg after the acrosome_ releases lytic enzymes dissolve the egg membrane.
The tail is left behind.
