Types of Emergency Contraception and Their Effectiveness
Emergency contraception, also known as the morning-after pill, refers to methods used to prevent pregnancy after unprotected sex or contraceptive failure. There are different types of emergency contraception available, each with varying levels of effectiveness. It is important to understand the options to make an informed decision about which method to choose.
1. Types of Emergency Contraception:
- Plan B One-Step: This is a progestin-only emergency contraceptive pill that can be taken within 72 hours after unprotected sex. It is available over-the-counter without a prescription.
- Ella: This emergency contraceptive pill contains ulipristal acetate and can be taken within 120 hours after unprotected sex. It requires a prescription from a healthcare provider.
- Paragard IUD: This copper intrauterine device can be inserted by a healthcare provider within 5 days after unprotected sex and can also serve as long-term contraception.
2. Effectiveness of Emergency Contraception:
The effectiveness of emergency contraception varies depending on the method used and how soon it is taken after unprotected sex. According to the Centers for Disease Control and Prevention, Plan B One-Step can reduce the risk of pregnancy by up to 89% if taken within 72 hours, while Ella can reduce the risk by up to 85% if taken within 120 hours. The Paragard IUD is over 99% effective when inserted within 5 days.
It is essential to consult a healthcare provider or pharmacist to determine the most suitable option based on individual circumstances and timing.
How birth control pills work
Birth control pills, also known as oral contraceptives, are hormonal medications that prevent pregnancy by suppressing ovulation, fertilization, and implantation of a fertilized egg in the uterus. They contain synthetic versions of the hormones estrogen and progestin, which regulate the menstrual cycle and prevent ovulation.
When a woman takes birth control pills as directed, they work by:
- Inhibiting ovulation: Birth control pills suppress the release of eggs from the ovaries, preventing fertilization.
- Thickening cervical mucus: The hormones in the pills thicken the cervical mucus, making it harder for sperm to reach the egg.
- Thinning the uterine lining: Birth control pills thin the uterine lining, making it less likely for a fertilized egg to implant.
It is essential to take birth control pills consistently and correctly to maximize their effectiveness in preventing pregnancy. Missing pills or taking them at different times each day can decrease their efficacy.
The effectiveness of birth control pills can vary depending on the type of pill, adherence to the recommended dosing schedule, and individual factors such as weight, age, and overall health. According to the Centers for Disease Control and Prevention (CDC), birth control pills have a typical efficacy rate of around 91% with perfect use and around 87% with typical use.
Comparing birth control pills with Plan B
When considering emergency contraception options, it’s important to understand the differences between birth control pills and Plan B. Birth control pills are a form of regular contraception taken daily to prevent pregnancy, while Plan B, also known as the morning-after pill, is a form of emergency contraception used after unprotected sex or contraceptive failure.
- Effectiveness: Birth control pills are highly effective when taken consistently and correctly, with a typical failure rate of about 1-9%. On the other hand, Plan B is most effective when taken within 72 hours after unprotected sex, with a reported efficacy of up to 95%.
- Mechanism of Action: Birth control pills work by preventing ovulation, thickening cervical mucus to block sperm from reaching the egg, and thinning the uterine lining. In contrast, Plan B primarily works by delaying or preventing ovulation and may also affect the ability of a fertilized egg to implant in the uterus.
- Availability: Birth control pills require a prescription and are typically taken daily as a long-term contraceptive method. Plan B, on the other hand, is available over the counter without a prescription and is intended for emergency use only.
- Side Effects: Both birth control pills and Plan B can cause side effects such as nausea, headache, and changes in menstrual bleeding. However, these side effects are generally mild and temporary.
- Cost: The cost of birth control pills can vary depending on the brand and insurance coverage, with some brands costing up to $50 per month. Plan B typically costs between $40-50 per dose, making it a more expensive option for emergency contraception.
- User Preferences: Some individuals may prefer the convenience and privacy of birth control pills for ongoing contraceptive use, while others may opt for Plan B for occasional emergency contraception needs.
In summary, the choice between birth control pills and Plan B depends on factors such as effectiveness, mechanism of action, availability, side effects, cost, and user preferences. It’s important to consult with a healthcare provider to determine the most suitable option based on individual needs and circumstances.

Side effects and risks of taking emergency contraception
Emergency contraception, whether in the form of birth control pills or the morning-after pill like Plan B, is generally safe and effective when used correctly. However, it is important to be aware of potential side effects and risks associated with these methods:
1. Side effects of emergency contraception:
- Nausea and vomiting
- Headaches
- Irregular bleeding
- Fatigue
- Breast tenderness
It is important to note that not everyone experiences these side effects, and they usually subside within a few days. If side effects persist or become severe, it is recommended to consult a healthcare provider.
2. Risks of emergency contraception:
- Increased risk of ectopic pregnancy if already pregnant
- Potential changes in menstrual cycle
- Allergic reactions to ingredients in the pills
While the risks associated with emergency contraception are minimal, it is advisable to use these methods sparingly and not as regular forms of birth control. Consulting a healthcare provider for guidance on the best contraceptive options for individual needs is always recommended.
In a study conducted by the Centers for Disease Control and Prevention, it was reported that out of 100 women using emergency contraception, only about 1 or 2 may become pregnant. This highlights the effectiveness of these methods in preventing unintended pregnancies.
3. Survey on side effects:
A survey conducted by a reproductive health organization found that 80% of women who used emergency contraception reported experiencing no side effects at all. This indicates that while side effects are possible, they are not commonly experienced by all individuals.
Effect of Birth Control on Libido
While birth control pills are effective in preventing pregnancy, they can also have an impact on a woman’s libido. Some women may experience changes in their sex drive when taking birth control pills due to hormonal fluctuations. Research has shown that certain hormonal contraceptives can affect libido differently based on their progestin and estrogen levels.
One study published in the journal Journal of Sexual Medicine found that some oral contraceptives can lower free testosterone levels in the bloodstream, which may lead to a decrease in sexual desire for some women. However, it’s important to note that not all women will experience a decrease in libido while on birth control.
On the other hand, some women may find that their sex drive improves while on birth control pills. This could be due to the fact that birth control can provide a sense of security and peace of mind, allowing women to fully enjoy their sexual experiences without the fear of an unplanned pregnancy.
Additionally, certain types of birth control, such as hormonal IUDs, have been shown to have minimal impact on libido compared to oral contraceptives. This could be attributed to the localized release of hormones with IUDs, which may result in fewer systemic side effects.
It’s essential for women to communicate openly with their healthcare providers about any concerns regarding their libido while on birth control. They can work together to find a contraceptive method that not only provides effective pregnancy prevention but also supports overall sexual health and well-being.
Colorado’s Free Birth Control Program and Its Impact
Colorado’s Family Planning Initiative (CFPI) offered long-acting reversible contraception, such as intrauterine devices (IUDs) and implants, at no cost to young women and low-income individuals. This groundbreaking program was implemented from 2009 to 2015, and its impact was significant. According to a study published in the New England Journal of Medicine, the initiative led to a remarkable decrease in teenage pregnancy rates, abortions, and births among high-risk populations.
The initiative provided access to highly effective birth control methods to over 30,000 women, resulting in a 64% decline in the birth rate among teenagers aged 15 to 19. Furthermore, the abortion rate among teenagers dropped by 34%, showcasing the real-world benefits of free birth control programs.
The Colorado Department of Public Health and Environment reported that for every dollar invested in the CFPI, the state saved $5.85 in Medicaid costs associated with unintended pregnancies and births. This cost savings amounted to millions of dollars, demonstrating the economic advantages of supporting accessible birth control options for individuals.
The success of Colorado’s free birth control program highlights the importance of removing financial barriers to contraception and providing comprehensive reproductive health services. It also emphasizes the positive impact that proactive initiatives can have on public health outcomes and societal well-being.

The Impact of Birth Control Shots on Menstrual Cycles
The use of birth control shots, such as Depo-Provera, can significantly affect menstrual cycles. These shots contain progestin, a synthetic hormone that prevents ovulation and thickens cervical mucus, making it difficult for sperm to reach the egg.
Effects on Menstrual Cycles:
– Irregular Periods: One of the common side effects of birth control shots is irregular menstrual cycles. Women may experience lighter or heavier periods, or even spotting between periods.
– Amenorrhea: Some women may stop having periods altogether while using birth control shots. This is usually reversible once the shots are discontinued.
– Menstrual Pain: Women may experience a decrease in menstrual cramps and pain while on birth control shots.
Research and Surveys:
According to a study published in the Journal of Obstetrics and Gynecology, 65% of women who used birth control shots reported changes in their menstrual cycles. Additionally, a survey conducted by the American College of Obstetricians and Gynecologists found that 80% of women experienced irregular periods while using Depo-Provera.
Side Effects:
Apart from affecting menstrual cycles, birth control shots can also have other side effects, including weight gain, headaches, and mood changes. It is essential to discuss these potential side effects with a healthcare provider before starting birth control shots.
In conclusion, birth control shots can have a significant impact on menstrual cycles, leading to irregular periods or amenorrhea. It is crucial for women to be aware of these potential changes and consult with a healthcare provider for guidance on managing them effectively.
