Sertoli cells are regulated by the pituitary hormone known as
a)	FSH	b)	GH	c)	Prolactin	d)	LH

(a)

Sertoli cells are the cells that line the seminiferous tubules in the testis. These cells protect the spermatids and convey nutrients to both the developing and mature spermatozoa. Sertoli cells are regulated by FSH (follicle stimulating hormone) as the FSH receptors are confined to the sertoli cells.
