I came across a really interesting blog the other day, though I don't know how credible the author, Dr. Licciardi, is. This post in particular led me to the blog.
In this post, Dr. Licciardi explains how the classification of sperm has evolved. He states that since Dr. Kruger introduced "strict criteria" for classifying sperm morphology, andrologists have been pickier and pickier in their classification. He claims that the average morphology numbers are actually in the range of 2-6% and almost every male is below the target cutoff of 14%. In his next blog post, Dr. Licciardi claims that abnormal sperm can fertilize eggs and make babies.
So what does this mean? I have no idea, but maybe Josh is more average than we thought.
