Our expert says:
Indeed there has been a revision of the bench mark for normal limits for sperm morphology and currently there is a proposal made to the WHO to accept 5% as normal. However this is not as yet universally accepted and more importantly the percentage of morphology should be viewed in combination with other parameters such as sperm concentration and motility factors as well as sperm DNA evaluation. It is quite possible that there is additional factor/s which may further confound the situation and it is always advisable to eliminate all contributing factors to the fertility problem. Even under the old criteria a morphology of 8% (provided that the sperm count and motility is good) is not entirely a major issue and therefore I would strongly urge you to have other factors looked at.
