Description

What is it? Fertilization is the primary step for making a baby. It occurs when the sperm from the male partner combines with the egg of the female partner, creating an embryo as a result. This process involves the following: Uterus Fallopian Tubes Sperm Healthy eggs Role of the Follicles Follicles are fluid-filled sacs present in the ovaries that contain one egg each and the cells that are necessary to prepare the egg for the early embryo development. The brain produces a hormone called Follicle Stimulating Hormone (FSH) that tells the follicles to grow and get bigger. When one of the follicles reaches a size of about 20mm, all of the others disintegrate. This big follicle will produce estrogen that will make the lining of the uterus t grown and prepare itself for pregnancy. The brain will then respond by producing the Luteinizing Hormone (LH) and it is present in the body for only a day per month.
