Iron Deficiency Flips Mouse Gender?!

Scientists just found that iron deficiency during pregnancy can actually cause male mouse embryos to develop female organs! Turns out, iron is crucial for activating the gene that makes male sex organs. Without enough iron, that gene gets blocked, and some XY embryos end up with ovaries instead of testes. Wild, right? This is the first time anyone’s shown nutrition can literally flip a genetic switch like this. No clue yet if it happens in humans, but it’s a total game-changer for how we think about development. #ScienceNews #Genetics #Pregnancy #Health #BodyHealth
