Patient's question:
What is the most effective method of contraception?Doctor's answer:
Hello:I. Safe Period Contraception
There are two methods for calculating the safe period:
1. Counting backward 14 days from the next menstrual period to determine the ovulation period. The 10 days before and after this period (5 days before to 4 days after) are considered the fertile period, while the remaining days are the safe period.
2. Continuously measuring basal body temperature for 2–3 menstrual cycles to understand the ovulation pattern and avoid sexual activity 5 days before and 5 days after ovulation.
Precautions: Not suitable for irregular menstrual cycles. Higher risk of unintended pregnancy.
II. Barrier Contraception
The most common form of barrier contraception is the intrauterine device (IUD). There are various types, including the T-shaped IUD (TCu380A), Mirena, Mirena, Gyni Ring, and ring-shaped IUD, etc.
Female barriers such as vaginal diaphragms and cervical caps require high usage accuracy and can be cumbersome and inconvenient.
Precautions: Before insertion, a doctor should examine the individual and determine if the IUD can be placed, as well as help select the most suitable type of IUD.
III. Hormonal Contraception
Hormonal contraceptives are categorized based on their duration of action into short-acting, rapid-acting, long-acting, emergency contraceptives, and contraceptive slow-release systems.
(1) Combined Short-Acting Oral Contraceptives (COCs): The earliest and most widely used method. Particularly suitable for newly married couples who do not wish to have children temporarily. Domestic brands include COC-1, COC-2, and COC-0. Other options include Marvelon, Microgynon-35, etc.
Precautions: Do not miss any doses during the medication period. If a dose is missed, take it the next morning.
