Thanks girls....
Ahurani- if you could, that would be great....
But if it's the one I'm thinking of, it's not suitable for fertility.
Surprised- how much psoriasis does your DH have?
A lot of the treatments available, do not suit my DH as he has severe psoriasis- ie more than 90% of his body is covered.
He did used to take a tablet, but again not suitable doe fertility.
