“The test measures the level of anti-Mullerian hormone (#AMH) in the blood and is known clinically as an AMH test.

AMH is produced by follicles in the ovaries (little fluid-filled sacs that contain immature eggs) and helps follicles and eggs grow during the menstrual cycle. Because the number of #follicles in the #ovaries drops with increasing age, the level of AMH also falls.”

Do you think about the mites that live in your #face #follicles and come out at #night while you #sleep? Maybe you should!

🧬 They’ve #evolved a tiny #genome.

💪🏻 Each leg segment is powered by only one #muscle cell.

😴 They follow your sleep cycles by responding to your #melatonin.

🧫 Lowest number of cells of any #arthropod.

If you find this intriguingly #weird, this paper is for you! 🤯
