Which Statement with Regard to Sertoli Cells is FALSE

Question

Which statement with regard to Sertoli cells is FALSE?
A) They secrete hormones.
B) They are joined by tight junctions.
C) They form a blood-testis barrier.
D) They phagocytize discarded sperm cytoplasm.
E) They help move the sperm into the blood.

Accepted Answer

Sertoli cells do not help move sperm into the blood. Instead, they support and nourish developing sperm cells, form the blood-testis barrier, phagocytize discarded sperm cytoplasm, and are joined by tight junctions. Sperm are eventually released into the seminiferous tubule lumen, not the blood.
