Humans attach a great amount of importance to all matters related to pregnancy, childbirth and the reproductive system is general. It is no wonder really that already a significant quantity of work has been done in related fields. Man has never been able to understand the human reproductive system in the manner which we have witnessed in recent years. The progress of science in different parts of the world is largely responsible for it. Amongst the different stages involved in human reproduction, the process of fertilization is one of the most important. The process of human fertilization has been discussed below.
During sexual intercourse, the sperm of a man enters the female body's vagina via the cervix. The process of ovulation also has a very important role to play in human fertilization. It is during ovulation that a mature ovum is released into the fallopian tube. It is important for an ovum to be available for the process of fertilization to be initiated. It is the ovum which is fertilized by the sperm and which results in the formation of the zygote, embryo and finally the fetus.

During the sexual intercourse, millions of sperms are released. But only one of the sperms is able to fertilize the ovum or the female egg. The process of human fertilization of the ovum by the sperm takes place in the fallopian tube. Fertilization involves the fusion of the nuclei of the sperm and the ovum leading to the formation of the zygote. Once the zygote is formed, it moves towards the uterus. After numerous transformations, the zygote is transformed into an embryo which remains attached to the inner linings of the uterus. Finally the embryo develops into a fetus and about nine months later childbirth takes place.
