Question

what does fertilization mean in human . explain it briefly ​

Answer 1

Explanation:

Fertilization Definition

Fertilization is the process by which male and female gametes are fused together, initiating the development of a new organism.

The male gamete or ’sperm’, and the female gamete, ’egg’ or ’ovum’ are specialized sex cells, which fuse together to begin the formation of a zygote during a process called sexual reproduction.

Types of Fertilization

Fertilization in Animals

The fertilization process in animals can occur either internally or externally, a difference which is largely determined by the method of birth. Animals which use viviparous and ovoviviparous reproduction (embryos develop within the animal’s body), and oviparous animals which lay hard shelled eggs, use internal fertilization.

Internal fertilization involves the union of sperm and eggs within the body of the (usually female) parent. In order for internal fertilization to occur, the male must implant his sperm into the female reproductive tracts. Implantation can be achieved by either: copulation, in which sperm transfer is performed by insertion of the penis or other male intromittent organ and ejaculation into the vagina, or cloaca: or by a cloacal kiss, in which two birds press their cloacae together and sperm transfer takes place. Some animals, such as mollusks, arachnids, salamanders and certain insects, transfer a spermatophore, a bundle or capsule containing sperm, which is stored within the cloaca until oviposition takes place.

Answer 2

Answer:

Human fertilization is the union of a human egg and sperm, usually occurring in the ampulla of the fallopian tube . The result of this union is the production of a zygote cell, or fertilized egg, initiating prenatal development . The most common sequence begins with ejaculation during copulation, follows with ovulation, and finishes with fertilization.
