The IUD produces mechanical stimulation of the endometrium, which can change the intrauterine environment and thus inhibit fertilization of the egg. It can be said that the IUD has the advantages of being safe, effective and long-lasting. However, there is still a possibility that pregnancy with an IUD may occur. Studies have shown that the chances of spontaneous miscarriage, premature birth, stillbirth, stillbirth and abnormal fetal development after conception with an IUD are greater than in normal pregnancies. Therefore, it is best to have an abortion as soon as possible in the event of a pregnancy with a ring. If you want to continue the pregnancy, you should intensify pregnancy checkups and be aware of the risks of pregnancy. The diaphragm is a water-soluble film made of a very strong spermicidal drug that can be used by both men and women. For men, it can be applied to the head of the penis and pushed deep into the vagina, while for women, it can be hand-delivered deep into the vagina and the film can be dissolved after 2 minutes for intercourse. If the film fails, abortion should be performed as soon as possible because the drugs in the film can affect the sperm and have a negative effect on the growth and development of the fertilized egg.
