Asthenoteratozoospermia is one of the most severe types of qualitative sperm defects.Most cases are due to mutations in genes encoding the components of sperm flagella,which have an ultrastructure similar to that of m...
Genetic factors play important roles in the etiology of male infertility.The routine clinical genetic testing for human spermatogenic failure is currently limited to abnormal karyotypes(e.g,47,XXY for Klinefelter synd...
