Currently, there is only one available birth control or contraceptive patch and this is the Ortho Evra birth control patch. The way that these contraceptive patches work is that they are applied to the surface of the skin, then the pregnancy is prevented through the release of estrogen and progestin hormones.
The woman generally applies the patch to the upper outside arm, abdomen, thigh, or buttocks. This application should take place on the first day of her menstrual cycle. It is from that day forward that she is to acknowledge this as her “patch change day”. This means that after one week, she will need to remove the patch and reapply a new one. She will need to repeat this again one week later, then on the final week, she does not wear a patch at all.
We can take a more in depth look at how the mechanism behind the birth control patch works. During ovulation, the female releases an oocyte (egg) that plays the crucial role in pregnancy. The birth control patch prevents a woman from ovulating, so without the release of the oocyte, the pregnancy is averted.
There is also another mechanism that takes place as a result of the birth control patch that deals with the sperm. Through changes in cervical mucus caused by the contraceptive patch, the sperm inhibited in its penetration.
When placed upon the skin, the Ortho Evra birth control patch releases a type of estrogen known as ethinyl estradiol and a type of progestin known as norelgestromin into the systemic circulation. This release is a gradual daily release.
