Development of prostate
prostate arises from a budding collection of tissue in the urogenital sinus.
The prostate develops from epithelial outgrowths form the prostatic segment of the urethra that grows into the surrounding mesenchyme.
This outgrowth and branching start at week 10 during embryo growth; by week 12, there are 5 groups of tubules that form the lobes of the prostate.
