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 #ChemSky 🧪

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.

Workplace support for menstruation and menopause

The chemical industry and universities are doing more to give chemists what they need to manage their menstrual health

Last Friday @elbafeo.bsky.social presented on PERIODically at the Supramol25 conference hosted by the Australian National University. We had the chance to speak to some amazing people afterwards and it was great to see people excited to talk about periods! Thank you to Supramol25 for having us! ❤️🧪🩸

What are the chemical triggers for menstruation? And what causes period cramps? This graphic, a collaboration with @periodically.bsky.social, looks at the chemistry behind the menstrual cycle: bit.ly/3ZkpqMz #ChemSky 🧪

Infographic on the chemistry of the menstrual cycle. The graphic highlights the two sub-cycles, the ovarian cycle and the uterian cycle, and the varying hormone levels during them.

Follicle stimulating hormone stimulates the growth of a follicle in the ovaries. After ovulation, levels drp to prevent development of multiple follicles.

Luteinising hormone triggers the release of an egg from the ovaries and starts the conversion of the follicle to a corpus luteum which is essential for establishing and maintaining pregnancy.

Estrogen, produced by the ovaries, causes the uterine lining to grow and triggers the production of luteinising hormone. Low levels of estrogen and progesterone cause the top layers of the uterine lining to break down - this is menstruation.

The corpus luteum releases progesterone which stimulates thickening of the uterine lining and the production of prostaglandins. Prostaglandins cause contractions which shed the uterine lining and cause cramps.
