How do oral contraceptives work?
How this type work? Similar to other hormonal methods of contraception (e.g. patch, injection, ring), oral contraceptives work in 3 ways:
• They stop your ovaries from releasing an egg each month (ovulation)
• They change the lining of your uterus, making it thinner and more difficult for a fertilized egg to implant
• It changes the composition of your cervical mucous, which makes it harder for the sperm to enter the uterus.
The above prove sure that it work well to prevent from pregnancy; but if you want to protect from HIV AIDS and pregnancy both together, condom still is the best choice.
