Male infertility due to large-headed multiflagellar polypoid spermatozoa is a male infertility due to sperm disorder characterized by the presence, in sperm, of a very high percentage of spermatozoa with enlarged head, irregular head shape, multiple flagella, and abnormal midpiece and acrosome. It is generally associated with severe oligoasthenozoospermia and a high rate of sperm chromosomal abnormalities (polyploidy, aneuploidy).
Features include always present findings: Multiflagellar spermatozoa, Male infertility, and Macrozoospermia.

AURKC encodes aurora kinase C (309 aa). Serine/threonine-protein kinase component of the chromosomal passenger complex (CPC), a complex that acts as a key regulator of mitosis. Highest expression in Testis (85.3 TPM) and Brain Cerebellar Hemisphere (5.9 TPM).
Spermatogenic failure 5 is caused by mutations in the AURKC gene on chromosome 19.
AURKC is classified as a druggable target (Druggable Genome, Enzyme, Kinase, and Serine Threonine Kinase categories) with score 2.8.
Genetic testing for AURKC is available. Testing is considered confirmatory for diagnosis.
Biomarker and diagnostic research for spermatogenic failure 5 has been reported in the published literature.
Phenotype severity distribution: 3 always present features.
No clinical trials have been registered for spermatogenic failure 5.
33 publications have been identified in PubMed for spermatogenic failure 5. Research spans Basic Science / Preclinical (45%), Diagnostic / Biomarker (15%), and Review / Meta-Analysis (12%).
