Clinical information of the acephalic spermatozoa syndrome patients
Sperm motility and the percentages of morphologically normal and abnormal spermatozoa were evaluated according to the World Health Organization guidelines (26). Most of the SUN5 mutation–associated spermatozoa were acephalic sperm with low motility. PR, progressive motility; NP, non-progressive motility; IM, immotility.
