Spermatocyte maturation arrest

A type of spermatogenesis maturation arrest in which the block of developmental occurs in the spermatocyte stage. Testicular histology shows seminiferous tubules with Sertoli cells, spermatogonial cells and spermatocytes but no further differentiated cells like round spermatids.

6 genes linked to Spermatocyte maturation arrest

Changes in these genes cause rare conditions in which Spermatocyte maturation arrest is seen. Most people with this trait have none of those conditions, and a gene on this list says nothing about anyone's own genome.

How often is among people with one of the gene's conditions, the most often across them, as the Human Phenotype Ontology records it. These pages describe traits and the research behind them; they are not a diagnosis, and a doctor or genetic counsellor is the person to ask about symptoms.
