Take Progestin To Prevent Pregnancy

Menstrual cycle is a process that occurs once every month to prepare a woman’s body for pregnancy. This is controlled by the hormonal changes. The reproductive organs which are affected by the menstrual cycle include the uterus, cervix, vagina, fallopian tubes and the ovaries. The ovaries produce two main hormones called Oestrogen and Progesterone. The oestrogen causes the ovaries to release an egg. This process is called Ovulation. Sexual intercourse during this period, the sperms from the man can fertilize the egg and initiate the beginning of pregnancy. In case the egg is not fertilized, the levels of the two hormones drop, causing menstruation. The most effective birth control pills are a combination of oestrogen and progestin. These maintain the levels of hormones inside the body at constant levels, thus preventing the onset of ovulation.
