There are plenty of reasons why you may need emergency contraception, but what isn’t clear to some women are the facts about how it actually works at preventing pregnancy. There are plenty of fallacies when it comes to emergency contraception that circulate the rumor mill – from horrendous side effects to infertility – that just aren’t true. If used correctly, emergency contraception is a safe way to decrease the risk of an unplanned pregnancy.
Holly Bullock, MD, an assistant professor in the University of Arizona Department of Obstetrics and Gynecology, who sees patients atBanner - University Medical Center Tucson，清除有关紧急避孕（EC）的三个神话，并分享了他们背后的真相。
Myth #1: The Morning-After Pill Is My Only Option
Not true, Dr. Bullock says. There are actually three options you can choose from:
1. Plan B One-Step and its generic versions is the most commonly used oral pill form of EC,根据to the American College of Obstetrics and Gynecologists (ACOG). This progesterone-only EC is available over-the-counter or behind-the-counter without age restrictions to men and women, but it isn’t your only option as a form of EC.
2. Another oral contraceptive pill is Ella, or ulipristal acetate, which requires a prescription. “Ella is more effective than Plan B or generics at delaying ovulation,” Dr. Bullock says. “and a prescription in advance should be offered to people before they need it. If your health care provider doesn’t offer it, be sure to ask for it!”
3. Copper intrauterine devices, like the Paragard in the US, can be inserted by a health care provider up to five days after unprotected sex, contraceptive failure, or after sexual assault.Accordingto ACOG, the copper IUD is the most effective method of EC.
“Sperm can live in the female reproductive tract for up to 6 days and the egg is available for fertilization for 24 hours,” Dr. Bullock says. “The copper kills the sperm and the oral ECs work to delay ovulation, so the sperm dies before the egg is released.”
Bullock博士补充说，关于铜宫宫的伟大之处是，它们可以作为EC以外的避孕药的长期形式。“只要您希望长达12年，它就可以使用。”
Myth #2: I Can’t Use EC More Than Once
多年的研究和经验表明，当EC多次服用EC时确实发生了怀孕的危险。但是Bullock博士说，也不会使您的定期节育形式形式。
“The oral EC methods, because they delay ovulation, are not recommended to be used more than once a cycle, and any sex thereafter should be protected,” Dr. Bullock says. “The copper IUD can continue to be used as a long-acting reversible contraceptive beyond its placement for EC.”
There are other reasons why EC shouldn’t become a habit.
- 其他方法更有效地预防怀孕。
- It can get costly and add up quickly. Even the generic form of Plan B can cost about $50 a dose.
- 有一些副作用。尽管无害，但您可能会遇到不规则时期，乳房压痛，恶心和呕吐等症状。
Myth #3: Taking EC Can Harm My Fertility
There’sno evidenceto suggest that EC has an adverse effect on your ability to get pregnant in the future. “Plan B and Ella both target the progesterone receptors and bind to them for a short while. Progesterone is a hormone found in birth control pills as well,” Dr. Bullock says. “There’s no harm done to your fertility or future plans to have children.”
However, these ECs do not protect against sexually transmitted diseases, such as herpes and HIV, which can affect pregnancy. Condoms are the only form of birth control that will protect you from STDs.
