How to avoid pregnancy after sex

Sexual intercourse is a prerequisite for pregnancy. Pregnancy is possible only when healthy sperm and egg combine closely and the embryo implants successfully. If you don't want to get pregnant, you also need to pay attention to many things during sex. Because once an unexpected pregnancy occurs, abortion can cause great harm to women, so contraceptive measures are important. So, how can you prevent pregnancy by having sex?

How to prevent pregnancy during intercourse

1. Taking birth control pills: Many people know how to use birth control pills, but these hormonal birth control pills are only suitable for women under the age of 39. Because women over the age of 40 have ovarian decline and are prone to menstrual disorders or amenorrhea, taking the pills is more likely to cause menstrual disorders (such as non-menstrual bleeding) or amenorrhea.

This type of emergency contraception is effective if taken within 72 hours, and recent studies have shown that it is also effective within 120 hours, but the sooner the contraceptive is taken, the better the effect. The side effects of this drug are relatively mild, mainly nausea, vomiting, headache, dizziness, fatigue, and early or late menstruation. Therefore, birth control pills are not suitable for routine contraception.

2. Place a copper-containing contraceptive ring: Place a copper-containing contraceptive ring in the uterus within 5 days after sexual intercourse. In recent years, some studies have shown that delaying the placement until 7-10 days after sexual intercourse can also have a good effect of post-coital contraception. The placement of an IUD is suitable for those who have already become pregnant and want to use it as a long-term contraceptive.

However, it is not recommended for women who have not yet become pregnant to have an IUD inserted. Women with gynecological tumors, pelvic inflammatory disease or reproductive tract infection are not suitable for IUD insertion. And women who have had an IUD placed must undergo regular follow-up visits as prescribed by their doctor.

For women before pregnancy, they should choose contraceptive methods that are effective and will not affect future fertility, and mainly choose short-term contraceptive methods. The preferred method is the short-acting contraceptive made from thorn seeds. You can also use condoms, external spermicides and other methods, but the actual effect of contraceptive measures is slightly inferior to that of contraceptives. After giving birth, women are advised to use more convenient long-term contraceptive methods. The main choices are estrogen-releasing intrauterine contraceptive systems, IUDs, and subcutaneous implants. It is usually placed by a professional and its contraceptive effect can last for 5-10 years.

Poor sexual habits of the couple

In order to prevent urinary tract infections, some couples develop the habit of waking up and urinating immediately after sex. However, this is not a safe way for couples who are already difficult to conceive, because urination can cause a large amount of semen to flow out, reducing the probability of sperm and egg fertilization.

Infrequent sexual activity

That is, too much or too little sexual activity can lead to infertility. Frequent sexual intercourse can cause a decrease in sperm count, reduced sperm quality, or the production of anti-sperm antibodies, leading to decreased fertility or infertility. And if the couple has too little sex, because the man does not ejaculate often, it will lead to metabolic problems in the growth and development of sperm, making the sperm activity rate low and unable to get pregnant.

Poor chances of having a couple

The best time for sexual intercourse to get pregnant is a few days before the scheduled ovulation period, on the scheduled ovulation period, and one day after the scheduled ovulation period. This period is called the "fertile period", and for couples who want to take contraceptive measures, it is the "dangerous period of pregnancy". If you have sex during your non-ovulatory period, it is generally not easy to get pregnant because you do not ovulate.

Incorrect sexual techniques: such as not having vaginal sex, sexual postures that are not conducive to semen reaching the cervix, as well as men not ejaculating during sexual intercourse, reverse ejaculation, difficulty in ejaculation, etc.
