The principle of contraceptive ring

For normal couples, the most important thing in their sexual life is the issue of children. If they do not want children, they usually use an IUD, which is the most direct and effective contraceptive method that will not harm the female body, and removal will not affect the reproductive function. The IUD is a common contraceptive device. Next we will introduce to you in detail the contraceptive principle of the IUD.

1. The copper ions in the copper intrauterine contraceptive ring aggravate the aseptic inflammatory response of the endometrium and interfere with the activity of the enzyme system necessary for implantation, which is not conducive to the implantation of the fertilized egg and the development of the blastocyst.

2. Copper ions may also change the biochemical properties of cervical mucus, affecting sperm activity and capacitation, thereby further enhancing the contraceptive effect. Copper ions can also directly kill sperm and fertilized eggs.

3. The role of prostaglandins: Long-term stimulation of the IUD causes the endometrium to produce prostaglandins. On the one hand, prostaglandins can enhance uterine contraction and fallopian tube peristalsis, causing fertilized eggs that are not sufficiently developed and divided to be sent to the uterine cavity prematurely, thus affecting implantation.

4. A large amount of prostaglandins can enhance the effect of estrogen, inhibiting the decidual reaction of the endometrium during pregnancy, which is not conducive to the implantation of the fertilized egg.

5. The ring can interfere with the normal cyclic changes of the endometrium, which is not conducive to implantation; it can also affect the transport or capacitation of sperm. Intrauterine devices containing high doses of levonorgestrel may also inhibit ovulation, change the properties of cervical mucus, and hinder sperm penetration.

The above contents are about some principles of contraceptive rings. When newlyweds do not want children to disturb their world of two, and are not ready to have children, the contraceptive ring can successfully solve everyone's problem. However, it should be noted that when using the contraceptive ring, women must go to a regular hospital for surgery.
