Abstract excerpt
Primary ciliary dyskinesia (PCD) is a severe sperm defect, leading to male infertility. PCD affects both respiratory function and sperm motility, as motile cilia and sperm flagella rely on axonemal architecture. Multiple morphological abnormalities of the sperm flagella (MMAF) is a distinct form of asthenoteratozoospermia, characterized by a heterogeneous spectrum of flagellar defects. In recent years,...
