How to Prevent Pregnancy Without Using Condoms or Rings?

For families who do not have plans for pregnancy, it is important to be mindful of the possibility of becoming pregnant during sexual activity. While pregnancy prevention can be achieved through methods such as wearing a condom or getting a ring, some individuals may prefer not to use these methods and still want to achieve the effect of pregnancy prevention. In general, men can ejaculate outside the body, but this method is not foolproof.

1. Safe Period Contraception Method

Safe period contraception is a method of avoiding pregnancy by abstaining from sexual activity during the ovulation period. The key to successful safe period contraception is determining the woman's ovulation date. The ovulation date generally occurs around 14 days before the next menstrual period. Sexual intercourse during the five days before and four days after ovulation is more likely to result in pregnancy, hence it is also known as the dangerous period. For those with regular menstrual cycles, determining the ovulation period is relatively simple, and can be estimated based on the menstrual cycle, specifically the 14th day before the next menstrual period. However, menstrual cycles can be affected by factors such as physical health, environmental changes, and emotional fluctuations, making the ovulation period estimated based on the menstrual cycle less accurate. Therefore, the failure rate of contraception is high, and this method is generally only suitable for those with normal menstrual cycles, who live together with their partner for a long time, and can correctly estimate the safe period. It is not recommended as the primary method of contraception.

2. Condom Contraception Method

The condom, also known as a safety cover, offers two main advantages in terms of safety. Firstly, compared to the safe period contraception method, it has a higher success rate in preventing pregnancy. If used correctly, the contraception rate can reach over 95%. Secondly, compared to methods such as oral contraceptives, the use of condoms has almost no side effects. Apart from preventing pregnancy, it can also prevent sexually transmitted diseases such as trichomoniasis, fungal vaginitis, bacterial vaginitis, genital herpes, genital warts, syphilis, and HIV/AIDS.

3. Oral Contraceptives

Oral contraceptives primarily consist of synthetic estrogens and progestins. They are classified into three types based on their duration of contraceptive effect: long-acting, short-acting, and emergency (for visiting relatives). Currently, the most commonly used are short-acting oral contraceptives. These contraceptives are easy to use, reliable in preventing pregnancy, harmless to the body, and do not affect future fertility. Typically, they are taken once a day for 21 days, starting on the 5th day of menstruation after dinner before bedtime, followed by a 7-day break before starting the next cycle. Emergency contraceptives are suitable for individuals visiting relatives for more than 10 consecutive days and can be taken after sexual intercourse, regardless of the menstrual cycle. If the visit exceeds two weeks, the contraceptive method should be changed.
