Hi Dutchie, I had heard the same as BDT with regards to the % take home rate from clinical trials and I have had my DH on it for the last month and although they say that you should be using it for 3 months we have just done our 1st IVF cycle and got a fert rate of 14 out of 15 and I definitely think that it has to do with the Menevit.. (DH not the healthiest human I know).. It works out at about $1.00 a day and I figure for the cost of our IVF it was nothing and ditto to BDT again for only having DH take one tablet... Good luck Dutchie..
