Adding this to your germination water to improve female %

Two questions, 1. I read on some forum somewhere that if you add a birth
control pill to your germination water it will increase the amount of females.
Sounds kinda crazy, could this be true?
2. On some online grow store they had a product you can add to your germination water and it could help you to have more females, has anyone
seen this and if so what is the product called and/or what places offer it.
It's been a long time so I can't remember. Thanks :confused: for any help. Have a great day everyone.

3. I forgot the rest, but there was extencive research about it by a university. I read it in here some where
