Apharmaceutical company is promoting a new estrogen skin patch for birth control. they say it is better because a woman only wears the patch for one week and then wears no patch for three weeks. explain the logic behind this proposal.

The birth control patch prevents pregnancy by stopping sperm from meeting an egg (which is called fertilization). Like most birth control pills, the patch contains the hormones estrogen and progestin, which are similar to hormones our bodies make naturally. You wear the patch on certain parts of your body, and the hormones are absorbed through your skin.

The patch stops your ovaries from releasing eggs (called ovulation). No ovulation means there’s no egg hanging around for sperm to fertilize, so pregnancy can’t happen.

The patch’s hormones also thicken the mucus on your cervix. Thicker cervical mucus makes it hard for sperm to swim to an egg — kind of like a sticky security guard.
