In an earlier study by Han et al., teratozoospermia datasets were intensively screened to find three potential biomarkers, namely, AGBL4, FAM172A, and RUNDC3B, in the teratozoospermia patient group [11], while another study identified differentiated genes in the case of patients suffering from azoospermia [24]. Here, RUNDC3B is linked to Abnormal sperm morphology.
