Why can I still get pregnant after having an IUD? It may be due to these factors

Many people wear IUDs because they don’t want to get pregnant, but some people still get pregnant even after wearing the IUD. At this time, most people don’t know why they can still get pregnant even though they have an IUD. In this case, it is likely that the IUD has expired or is in an abnormal position.

1. The validity period has expired

"If you get pregnant with an IUD, one of the factors to consider is that the IUD has passed its 'use period'. Or different types of IUDs for ectopic pregnancy have different use periods. Stainless steel metal IUDs can be placed for about 20 years and removed six months after menopause; plastic or silicone rubber IUDs can be placed for 3 to 5 years; plastic-steel hybrid rings can be placed for 5 to 10 years; copper IUDs can be placed for 3 to 5 years; those with copper sleeves instead of steel wires can be placed for 10 to 15 years; progesterone IUDs generally have their progesterone hormones almost completely released after one year and need to be replaced year by year. So we should be wary of IUDs 'overdue' and women who have IUDs should have regular checkups and replace them on time."

2. Why can I still get pregnant when the contraceptive ring is within its validity period?

The expert explained: "In fact, some pregnancies are caused by the IUD falling off quietly, but the women don't know it has fallen off. In addition, clinically, about 10% to 15% of women are pregnant with the IUD. There are roughly two types of pregnancy with the IUD, intrauterine pregnancy and ectopic pregnancy."

3. Others

There are many reasons for pregnancy with an IUD: the IUD is positioned ectopically in the uterine cavity; the inert IUD itself has insufficient anti-fertility effect; the IUD is deformed, which reduces its contact area with the endometrium; the IUD is placed before the uterine cavity has returned to normal after delivery or abortion; severe cervical lacerations can cause the internal cervical os to deform and relax, and change the morphology of the uterine cavity, resulting in the shape and size of the IUD not matching the shape and size of the uterine cavity and its position lowering; the endometrium covers the IUD; uterine malformations, etc.
