What Is The Process Of Fertilization?

Fertilization happens a week after your menstruation cycle has ended or 14 days after your last menstrual cycle. After about 7-10 days the fertilized ovum gets planted in to the lining of the womb. By the end of another week it is firmly attached by its primal placenta which links the developing embryo to its mother.

The ovum is released from the surface of the ovary around the 14th day of the cycle. It is caught in the funnel shaped end of the Fallopian tube and is propelled along it by muscular contractions.Fertilization by one sperm occurs about a third of the way along the tube. The fertilized cell divides in two within twenty four hours.

With repeated cell divisions a ball of cells is formed. The egg continues to divide as it is swept along the tube. An empty opening, known as the blastocyst, forms on the ball of cells, which reaches the cavity of the uterus.Implantation begins around day 7 and is most commonly in the upper part of the uterus on either side depending on whether the left or right ovary ovulated. By day 10 the embryo is firmly implanted.
