Sperm consists of three main structural sections: the head, the midpiece (or neck), and the tail. Sperm morphology disorder, or teratospermia, refers to the presence of structural abnormalities in any of these sections (head, midpiece, or tail) that deviate from the normally expected form. Currently, the evaluation of semen samples is performed on prepared slides under a microscope using special staining techniques. According to the World Health Organization (WHO) criteria, a sperm count with normal morphology of at least 4% of the total sperm count is considered healthy.
