There are some great values here for unit conversion & stoichiometry questions for HS Chemistry. Eg. what is the minimum number of copper ions needed for an effective copper IUD that is used for 10 years? How many moles is that? #iteachchemistry #chemistryeducation

Today is #MenstrualHealthDay 🩸 To mark it, here's the second of my graphical collaborations with @periodically.bsky.social looking at the chemistry behind intrauterine devices and how they prevent pregnancy: wp.me/s4aPLT-iuds

Infographic on the chemistry of IUDs. Intrauterine devices (IUDs) are among the most effective forms of birth control. These devices are inserted into the uterus and do not need to be replaced for several years. There are two types of IUD available: copper IUDs and hormonal IUDs. Copper IUDs slowly release copper ions into the uterine fluid, reducing the movement of sperm cells. Hormonal IUDs release a synthetic form of the hormone progesterone to prevent ovulation.
