Antihistamines and sperm health

Hi all,

My husband suffers badly with hayfever. We are looking at going into another IVF cycle in the coming months and I’ve just read that antihistamines can have a negative impact on male sexual hormones in the testicles, including reduced sperm count, altered morphology and decreased motility.

He currently takes fexofenadine to help alleviate some of the hayfever symptoms but I am hoping someone in the know could advise if there are any ‘better’ options.

He did try a natural remedy last year but found he was allergic to that too! (A spoonful of local honey each day)

Any help or advice would be hugely appreciated!

Thanks
