Detailed explanation-1: -Fertilization is the natural life process, which is carried out by the fusion of both male and female gametes, which results in the formation of a zygote. In humans, the process of fertilization takes place in the fallopian tube.

Detailed explanation-2: -Fertilisation is the fusion of the nucleus of a male gamete with the nucleus of a female gamete. In humans, each gamete has half the number of the total 46 chromosomes that the body requires. The 23 chromosomes within a gamete are referred to as a haploid.

Detailed explanation-3: -During fertilization, the sperm and egg unite in one of the fallopian tubes to form a zygote. Then the zygote travels down the fallopian tube, where it becomes a morula. Once it reaches the uterus, the morula becomes a blastocyst. The blastocyst then burrows into the uterine lining-a process called implantation.

Detailed explanation-4: -There are three main stages in fertilization: sperm capacitation and acrosome reaction, sperm-egg binding and fusion, and cortical reaction and oocyte activation. Briefly, sperm capacitation occurs in the female genital tract and prepares sperm cells for the acrosome reaction.
