You can read the story of 0+12 here. The inventor of o+12 use to post on bc many years ago. She found a study and it made since to her. This was before the 7 sway factors and she only did timing. Based on o+12 alone she got her daughter. She stayed around bc for a while before leaving.
When I was first looking into MSU and experimenting my first contact with a doctor was a complex one. I was on the chat forum on ig here (it use to be for all members) when a doctor from E. came into the chat room. This doctor was not happy that we were doing what they felt was E at home and not paying for it in a lab. The the words of the doc: how dare you sort sperm in your bathroom! You should be forced to pay for such services. Well at first I was shocked, but then I realized that a doc came, found me and confermeded what we were doing was sorting sperm! It was working! Later a different Doc from Ireland emailed me. He had looked over all my research and all my steps. This doctor was greatly impressed by our work and said it would work. He didn't think the % is as good as the studies I posted but with the combo of all 7 sway factors he felt we would be MORE successful than E. Finally a 3rd doctor looked over all the extreme methods and told me that they are all 100% safe, you can not damage sperm dna. That no amount of playing with sperm can cause mc.
Finally I made fast Friends with a biologist the bc board. There is way more info about this earlier in my blog. She helped me to come up with egs su/gdc and msu. She really knows her stuff.
