I dont have any help really with MALE psoriasis, but I have psoriasis, and the meds I am on (methotrexate and prednisolone) can't be taken while pregnant or breast feeding. I know the methotrexate effects folate.. which I know is important for a women during TTC, but I am not sure about a man ???

Mine is immune/hormone based psoriasis caused by pregnancy (so we think) it started randomly after i had my daughter, and the only meds that work are immune suppresants (creams do jack all) and it flares with my monthly cycle.

So sorry, probably not any help, but just thought i would share

Hopefully your FS can help!!!
