Please ask again?


Which is more effective for contraception, taking oral contraceptives or using condoms? What is the effectiveness rate of condoms? What are the reasons for failure? If used correctly throughout the entire intercourse without any breakage, what happens? Does the pharmacy sell these products?

Xin, 10~19 year old female. Ask Date: 2010/01/27

Dr. Lü Lizheng reply Obstetrics and Gynecology


Hello: The effectiveness of taking pre-coital contraceptive pills and using condoms is both very high, achieving up to 99% effectiveness.
The main reason for condom failure is using them too late; they must be used from the very beginning and throughout the entire intercourse.
Each pharmacy may carry different brands of contraceptive pills, so it is advisable to try several options.
Wishing you health and happiness.
Sincerely, Dr.
Li-Cheng Lu, Attending Physician, Department of Obstetrics and Gynecology, Taoyuan General Hospital, Ministry of Health and Welfare.

More Info


When comparing contraceptive methods such as birth control pills and condoms, it's essential to understand their effectiveness, mechanisms, and potential drawbacks.
Effectiveness:
Birth control pills, when taken correctly, are about 99% effective at preventing pregnancy. This means that fewer than 1 in 100 women will become pregnant in a year of perfect use. However, typical use, which accounts for missed pills or taking them at irregular times, reduces this effectiveness to about 91%.
On the other hand, condoms have a typical use effectiveness of around 85%, meaning that about 15 out of 100 women will become pregnant in a year of typical use. With perfect use, condoms can be about 98% effective. The effectiveness of condoms can be compromised by incorrect usage, breakage, or slippage during intercourse.

Reasons for Failure:
The failure of both methods can be attributed to various factors. For birth control pills, common reasons include forgetting to take a pill, taking pills at inconsistent times, or interactions with other medications that may reduce their effectiveness.
For condoms, failure can occur due to improper application, using expired or damaged condoms, or not using them throughout the entire sexual encounter. Even with careful use, there is still a small risk of breakage or slippage, which can lead to unintended pregnancy.

Combination Use:
Using both methods together can significantly increase contraceptive effectiveness. This dual method not only provides a high level of pregnancy prevention but also offers protection against sexually transmitted infections (STIs), which birth control pills do not.

Availability:
As for the availability of contraceptive methods, birth control pills can be obtained through a prescription from a healthcare provider, while condoms are widely available over-the-counter at pharmacies, grocery stores, and online. You can find them at your local pharmacy, including places like 悅姿藥局 (Yuezi Pharmacy).

Conclusion:
In summary, while birth control pills offer a higher effectiveness rate when used perfectly, they require consistent daily intake and a prescription. Condoms, while slightly less effective, provide the added benefit of STI protection and are easily accessible. For optimal protection against pregnancy and STIs, consider using both methods together. Always consult with a healthcare provider to determine the best contraceptive method for your individual needs and circumstances.
