What does the ortho evra birth control patch actual do...how does it work?
Answers: those arent good for you. here are daytime commercials on that.
When worn the ORTHO EVRA Patch , delivers a steady flow of hormones through the skin and into the bloodstream over a time of year of 7 days. ORTHO EVRA contains the same hormones found within the Pill—progestin and estrogen.
It works in like peas in a pod manner as the pill, but the drugs are deliver through the skin, rather than by mouth.
The primary method is by preventing ovulation - no egg=no pregnancy. However this solitary works in nearly 80-90% of women.
The secondary method is by thinning the inside layer of the uterus to an extent that a fertilised egg cannot implant. No implantation=no pregnancy. It also make for lighter periods.
The third backup method is it thicken the cervical mucus, making it more difficult for sperm to reach the uterus and find an egg.
