I read a LOT of things about test being used as the male contraceptive in other countries, so I thought Id experiment myself as we wanted a baby anyway. Wife got pregnant instantly! So I wouldnt even say mine were reduced, but I guess you cant really tell just from that!

I have heard that if you look at your sperm, thick n white means high sperm count and ony patches of white, and wuite thin means low sperm count - mine was high all the time going by this
