This has been talked about since i was a teenager (im now in my early 50s so not personally affected any more) but it looks like American scientists may have cracked it. YCT-529 prevents sperm production without affecting testosterone levels or disrupting libido. It targets a protein called retinoic acid receptor alpha which plays a crucial role in making sperm. By blocking this receptor the drug stops sperm production without interfering with male hormones.
Im too old to worry about this now personally but if this had been available when i was younger i would have said no and continued with my own contraception being childfree by choice.
So would posters here think that men should share the burden of contraception re a Pill or would you want to stay in control?
