KNOW HOW CONTRACEPTIVES WORKS. We have four types of contraceptive: 1:Hormonal contraceptives 2:Barrier contraceptives 3:Intrauterine devices(coils) 4:sterlirization Hormonal contraceptives primarily alters the reproductive hormones that are released during menstrual cycle,menstrualcycle is counted from day one of bleeding,the cycle ingeneral lasts 28days.The menstrual cycle is divided into three broad phases: 1:The follicular phase,(day 1-13) during this phase,the growth of a follicle in the ovary is stimulated by one of the reproductive hormones called )FSH)this hormone releases the ovumÖegg,FSH,also stimuleates the lining f uterusÖwomb,in preparation for pregnancy. 2:Ovulation phase(day 13-16)this phase is conception phase,a Luteinising hormone triggers the release of the ovum from a mature follicle,this reliease is the once reffered to as OVULATION,once released,the ovum travels to the fallopian tubes where if sperms are present,fertilisation takes place.A woman has just 3days per month which she can be pregnant. 3:The luteal phase(day 16-28)at this stage,3rd reproductive hormone,called progesterone is released,if the ovum was fertilised,progesterone sustains the pregnancy,if no fertilization took place,hormone progesterone stops and the lining of uterus is send as menstrual blood. #prince
