Someone suggested I discuss what was talked about with all the past people. So I will label these by parts. This is party one and will included the inventor of preseed, the acijell and vinegar study
I cant really recall the year it was, but when preseed first came out, the inventor/doctor had a forum. His forum was to handle questions about his product. This was very fascinating to me so I posted several time. We discussed the pH of the product, its reaction to sperm and its effect on swaying. His first comment was he didn't know about swaying so he couldn't comment on that lol. He did say that the small test sample he did found to favor girls. But 1 out of 4 people only turned in there surveys so the survey on this subject was not accurate. His next one was a detailed explanation of the pH and how it works. It was really fascinating! He spent many years working out the perfect pH to keep all sperm alive the longest. We talked about how some sperm can handle different levels of sodium and others can not. In conclusion i think pre-seed only slightly sways for a boy, maybe by 1-3% mainly because the pH is around 7. Do I think those ttc a girl should use it? Nope.
The inventor of aciell showed up on the baby center forums back when I was pg with dd2 so that had to be in 2005. He saw the interest in swaying and thought of it as a money maker. He posted here and their on the forum asking women questions then came up with his jell. However he found he could not market for swaying (fda or something not allowing it) and discovered he could use it to lower pH for women who have repeat infections. So he marketed it for that and dropped the swaying idea; however it was the same product. Now in 2009 the product was recalled due to a error in manufacturing. There has been no news if it will come back.
The vinegar study story is very long and complicated. I wont go into much, but lets just say we don't see eye to eye. I like his research and have imported parts of it into swaying.
