Alesse is a drug that women take regularly to prevent pregnancy. The medicine contains an estrogen and a progestin. Due to such combination of hormones the ovulation doesn’t occur. The fluid from the vagina gets thicker and prevents ovum fertilization. The drug doesn’t also let the fertilized egg attach to the womb. When the egg doesn’t attach, it will surely leave the body during the menstruation. Pills help to make the menstruation more regular, kill the periodic pain and reduce the amount of blood loss. They are effective in acne treatment and in preventing the risk of ovarian cysts.
