Question

Describe the process of fertilisation in human beings by zigya

Answer 1

process of fertilization involves a sperm fusing with an ovum. The most common sequence begins with ejaculation during copulation, follows with ovulation, and finishes with fertilization. Various exceptions to this sequence are possible, including artificial insemination, in vitro fertilization, external ejaculation without copulation, or copulation shortly after ovulation.[3][4][5] Upon encountering the secondary oocyte, the acrosome of the sperm produces enzymes which allow it to burrow through the outer jelly coat of the egg. The sperm plasma, then fuses with the egg's plasma membrane, the sperm head disconnects from its flagellum and the egg travels down the Fallopian tube to reach the uterus.

Answer 2

Answer:

• Fertilization is defined as the process in which there is a fusion of male

gamete and female gamete.

• The male gametes or sperms are released from the male reproductive

organ called the penis.

• The sperms release and enter the female body through the vagina.

• From the vagina, sperms travel through the fallopian tubes where they

meet the eggs.

• From there on, the process of fertilization takes place in the fallopian

tube.

• The male gamete cell (sperm) and female gamete cell (egg) fuse

together to form a zygote.

• The zygote divides rapidly to form a group of cells called morula, which

becomes the embryo after approximately five days. The foetus is

present for about eight weeks after the fertilization.
