Because spermatogonia don't begin to divide and produce spermatocytes until puberty, spermatocyte-and sperm-specific proteins are not present for a significant portion of the time when the immune system is eliminating self-reactive cells. Thus, it is not impossible to find sexually mature males with high levels of anti-sperm antibodies. Such antibodies can be shown to react against and interfere with sperm in vitro. These same males, however, are not necessarily infertile due to features of:


A. spermatogonia.
B. myoepithelial cells.
C. endothelial cells.
D. Leydig cells.
E. Sertoli cells.

Sertoli cell has been called the "mother" or "nurse" cell. Translocation of germ cells from the base to the lumen of the seminiferous tubules occurs by conformational changes in the lateral margins of the Sertoli cells.

During the maturation phase of spermiogenesis, the Sertoli cells consume the unneeded portions of the spermatozoa
