But the difference is that the child's mother is actually a cesarean section, after the baby is born, the doctor casually removes the IUD in the uterus, and then puts it in the baby's hand, and this photo appears, speaking of which many women begin to wonder, why can the mother get pregnant after birth control? The following obstetrics experts from the maternity hospital give you an explanation.

IUD "upper ring", medically our special term for intrauterine device, is a contraceptive device that can be placed in the uterine cavity, with safe, effective, simple, economical and reversible characteristics, its contraceptive rate is as high as 90%. But like ordinary contraceptives, although the contraceptive rate is high, there is still a chance of pregnancy, so there will be a very small number of people who will still get pregnant after placement.
Why do I get pregnant with a contraceptive ring?
Normally, the effect after the contraceptive ring is very good, the probability of unintended pregnancy is very small, but if there is no regular maintenance or the size of the contraceptive ring is not suitable, the contraceptive ring may fall or move, or the contraceptive ring has reached the service life and is not immediately removed, etc., which is likely to cause the contraceptive ring to be ineffective and increase the risk of unintended pregnancy.
What is the contraceptive mechanism of IUDs?
1. Prostaglandin effect
Due to long-term stimulation of the birth control ring, the endometrium secretes a large amount of prostaglandins. Prostaglandins promote uterine contractions, enhance fallopian tube peristalsis, and promote the rapid transport of fertilized eggs to the uterine cavity in advance, thereby affecting fertilized egg implantation. In addition, prostaglandins can enhance the effect of estrogen, inhibit the decidual reaction of the endometrium, and interfere with the implantation of fertilized eggs.
2. Interfere with the intrauterine environment
Placing the birth control ring into the uterine cavity not only acts as a mechanical obstacle, but also promotes an inflammatory response in the endometrium, which is not bacterial but mild, can increase the number of white blood cells, and affect the implantation of the fertilized egg.

3. Interference with the endometrium
The birth control ring in which progestogen is placed can slowly release progesterone in the body, disrupt the normal cycle changes of the endometrium, and promote the endometrium to be at high progesterone levels for a long time, which in turn causes gland atrophy.

At the same time, the slow release of progestogens can cause interstitial deciduation, affecting the implantation of fertilized eggs, or affecting the delivery and union of eggs by sperm in the woman's body; But the progesterone birth control ring also changes the nature of cervical mucus and prevents sperm penetration.
4. Increase endometrial inflammation
The steel birth control ring continuously releases copper ions in the body, causing aseptic inflammation of the endometrium, and also disrupts the endometrial enzyme system to prevent implantation of fertilized eggs. At the same time, it can also change the cervical mucus, affecting sperm activity and survival, thus serving the purpose of contraception.
[Breeze] [Breeze] Finally, warm reminder: In addition to intrauterine devices, there are many ways to do contraception, such as: oral contraceptives, condoms, etc., no matter which contraceptive method, it is less harmful to the body than having a last resort to abortion after contraceptive failure. So, if you don't have plans to have a baby, be sure to use contraception! Everyone must not follow this mother, because if you do not pay attention, pregnancy with a loop is very risky, not only will lead to amniotic water pollution, but also very easy to lead to miscarriage, fetal malformations and other problems.
