For so long, contraception has been a woman’s burden. The pill. The IUD. The implant. The patch. While condoms and vasectomies exist for people who produce sperm, the responsibility for preventing pregnancy has overwhelmingly fallen on those with ovaries.
But what if that changed?
Luke Baz at The University of Melbourne is working on a non-hormonal contraceptive that targets sperm. He is trying to block the specific proteins – molecular “on switches” – that sperm need to fertilise an egg. It’s about precision. It’s about reversibility. And it’s about finally shifting the load.
This week, we’re swimming in the science of sperm, the biology of fertilisation, and the cutting-edge research that could revolutionise reproductive autonomy. The future of birth control could be more equitable than ever before. And it starts with understanding sperm.
