    Intracytoplasmic Sperm Injection pp Cite as. Background: Sperm morphology is an important factor impacting male fertility potential. Thus, the assessment of this parameter is a key step during the infertility diagnosis and in real-time selection of sperm for intracytoplasmic sperm injection ICSI. In recent years, one interesting subject in sperm morphology analysis SMA involves use of an automated algorithm. These algorithms can accelerate detection of typical and atypical forms. This chapter presents one of the most successful SMA algorithms for use in real-time analysis of human sperm selection.

    What Does Sperm Motility Mean?

    The assessment of the percentage of spermatozoa having an 'ideal' morphology using so-called strict method is the method recommended in the latest edition of the World Health Organization WHO laboratory manual for semen analysis. This recommendation is a result of the statistical association between 'ideal' sperm morphology and fertility, and of the current general belief that sperm morphology assessment should be used primarily as a fertility tool. The notion of an 'ideal' sperm morphology has persisted despite the very low percentage of such spermatozoa in the semen of fertile men, a subject of intense controversy. The detailed categorization of each abnormal spermatozoon has thus, for a long time, been considered optional and partially redundant, an idea which is reflected in the earlier editions of the WHO manual. However, several recent studies have shown the importance of carefully assessing abnormal sperm morphology for use in the diagnosis of infertility, to determine fertility prognosis, and for basic or public health studies. One approach, which combines videomicroscopy and computer vision, and is the only approach able to assess the continuum of sperm biometrics, has been used successfully in several recent clinical, basic and toxicology studies. In summary, the visual assessment of detailed sperm morphology—including the categorization of anomalies allowing arithmetically derived indices of teratozoospermia—and the more modern computer-based approaches, although often considered to be redundant, are in fact complementary.
