My OH has a low sperm count too,
He is now taking Sanatgen Pre Natal (His) tablets with added zinc to help his swimmers.
He has started riding to work every day, he is quite fit anyway, cut down on alcohol, both trying to eat more healthily - more fruit etc. I have heard that tomato soup helps although not tried it!!
The lady that gave my OH the test results said that the worry and stress of doing the test can affect the sperm count as it is not a nice thing to have to do!
We have been referred to a fertility specialist so we will see how that goes, has his doctor also done this? Have you had any tests done?
Just keep reminding yourself, it only takes one!!! xx
