Description:Humans[ edit ] The human sperm cell is the reproductive cell in males and will only survive in warm environments; once it leaves the male body the sperm's survival likelihood is reduced and it may die, thereby decreasing the total sperm quality. Sperm cells come in two types, "female" and "male". Sperm cells that give rise to female XX offspring after fertilization differ in that they carry an X-chromosome, while sperm cells that give rise to male XY offspring carry a Y-chromosome. Human sperm cells consist of a flat, disc shaped head 5. It has a compact nucleus with only chromatic substance and is surrounded by only a thin rim of cytoplasm. Above the nucleus lies a cap-like structure called the acrosome, formed by modification of the Golgi body and which secretes enzyme spermlysin hyaluronidase, corona-penetrating enzyme, zona eyesin, or aerosin.
