It is accompanied by changes in maturation markers in the oocytes (from OCT3/4, to deleted in azoospermia-like [DAZL], and then to VASA [also known as mouse vasa homolog, MVH], or DEAD [Asp-Glu-Ala-Asp] box polypeptide 4 [DDX4]) and in the GREL/granulosa cells (from replication markers to expression of FOXL2 [forkhead box L2]). Here, FOXL2 is linked to Azoospermia.
