tes·tic·u·lar dys·gen·e·sis

[MIM*305700]
a congenital derangement of seminiferous tubular structure and function, resulting in male infertility; the defect in spermatogenesis may be incomplete, as in maturational arrest or premature sloughing, or spermatogenesis may be completely absent, as in the Sertoli-cell-only syndrome.
