A rare, genetic male infertility due to sperm disorder characterized by the presence of spermatozoa with abnormal morphology, such as macrozoospermia or globozoospermia, in over 85% of sperm, resulting from mutation in a single gene known to cause teratozoospermia. It is a heterogeneous group that includes a wide range of abnormal sperm phenotypes affecting, solely or simultaneously, head, neck, midpiece, and/or tail.
Features include very common findings: Phenotypic abnormality, Increased circulating gonadotropin level, Abnormal spermatogenesis, and Decreased testicular size and others.
Phenotype severity distribution: 8 very common features.
No clinical trials have been registered for male infertility with teratozoospermia due to single gene mutation.
1 publication has been identified in PubMed for male infertility with teratozoospermia due to single gene mutation. Research spans Review / Meta-Analysis (100%).
