Description : In the evaluation of male infertility, the Sertoli cell-only (SCO) syndrome is diagnosed
on testicular biopsy when either no germ cells are visible in any seminiferous tubules
(SCO type I) or germ cells are present in a minority of tubules (SCO type II). It
is believed that the latter variant arises from a failure to complete differentiation
and maturation of spermatocytes and spermatids, leading to degeneration of germ cells
within most tubules (Sargent et al., 1999). Another, possibly X-linked, form of Sertoli
cell-only syndrome has also been reported (305700). - Heterogeneity of Spermatogenic
Failure See 415000 for a general discussion of the AZF region of the Y chromosome
and Y-linked nonobstructive spermatogenic failure. For a discussion of phenotypic
and genetic heterogeneity of spermatogenic failure, see SPGF1 (258150).;
