How is it even possible to get pregnant while having an IUD?

77 viewsBiologyOther

I’ve read the effectiveness is over 99%, specially with hormonal IUDs like Kyleena. What happens to the rest of the people? Are they just built different? How is it possible that the egg still gets fertilised and implanted even with all those hormones making the uterus lining thin for implantation and the cervical mucus too thick for the sperm to get to the egg in the first place?

Most IUD failures are a result of the IUD getting dislodged out of place.
The most recent number I heard was 99.8% effective over 1 year (2 pregnancies in 1000 patients).
