Introduction

Historic testis drawing

The male gonad is the testis. The initial difference in male and female gonad development are dependent on testis-determining factor (TDF) the protein product of the Y chromosome SRY gene. Recent studies have indicated that additional factors may also be required for full differentiation.

The seminiferous tubules are considered the parenchyma of the testis.
