The studies that people point to when it comes to phytoestrogen is the one that found that it reduces sperm count.
However if you look at the study, you notice that the conclusions are misleading. Sperm count is reduced because soy stimulates the prostate gland into creating more ejaculate volume. The number of sperm remains the same, but if you take a 1ml sample for instance and compare it, it will appear to be less. When in reality the overall sperm count is unaffected.
There isn't really any other studies that soy or phytoestrogens are necessarily bad for male health or fertility.
