Interstitial cells are also called
a)	Leydig cells	b)	Rete testis	c)	Vasa efferentia	d)	Spermatocytes

Leydig’s Cells

(Interstitial Cells)

Sertoli Cells

(Sustentacular Cells)

They are present in between the seminiferous tubules.

Leydig’s cells are found in small groups and are rounded in shape.

They secrete andogens (  testosterone) male sex hormones

They are present in between the germinal epithelial cells of the seminiferous tubules.

Sertoli cells are found singly and are elongated

They provide nourishment to the developing spermatozoa (sperms). Sertoli cells secrete ABP (Androgen Binding Protein) that concentrates testosterone in the seminiferous tubules. It also secretes another protein inhibin which suppresses FSH synthesis
