Answer:
Explanation:
1 Hormonal birth control methods prevent the ovaries from releasing eggs, thicken the mucus of the cervix to prevent sperm from entering the uterus, and thin the lining of the uterus to prevent implantation.
2 Typical use means how well the method works to prevent pregnancy when people use it in real life, while perfect use means how well the method works when it is being tested in a clinical trial. by people who are following the instructions to the letter always and for a full year. For example, a perfect use effectiveness rate of 99% means that over the course of a year, on average, 1 out of 100 people who used this method as directed will get pregnant.
Since life is not a clinical trial, we recommend that more attention be paid to numbers that reflect typical use of the method. But you can get closer to the perfect number if you learn to use the method correctly and consistently.
Some methods, such as the IUD and the implant, have a typical use rate very similar to the perfect use rate. This is because in these methods there is very little room for error because the person does not have to do or remember anything, they just have to change it from time to time. Other methods, such as condoms, have a more drastic difference between typical and perfect use rates, because there is more opportunity to make a mistake when using these contraceptive methods.
3 Blood pregnancy tests are about 99% accurate. The blood test is often used to confirm the results of a home pregnancy test.
