Lecithin = Estrogen?

[GrumpyOldMan]

I want to increase my sperm volume and I see that Lecithin is one of the magic ingredients. But I was wondering about the Soy and Estrogen link, since Lecithin is made from Soy beans. I could not see any major links when I googled. I plan to take between 1tsp to 1 tbsp of granules in my shake daily.
