Introduction
The male and female reproductive systems develop initially "indifferently", it is the product of the Y chromosome SRY gene that makes the "difference". The mesonephric duct (Wolffian Duct) contributes the majority of male internal genital tract. The embryonic gonad development leads to the mesonephric/paramesonephric duct changes, while the external genitaila remain indeterminate in appearance through to the fetal period. Importantly its sex chromosome dependence, late embryonic/fetal differential development, complex morphogenic changes, long time-course, hormonal sensitivity and hormonal influences make it a system prone to many different abnormalities.
The prostate gland is generally recognised due to its late postnatal adult growth changes, rather than its embryonic development, and the health effects of prostate cancer.
There are also currently separate pages describing Spermatozoa Development | Testis Development | Prostate Development.

Mouse Prostate
Androgenic regulation of ventral epithelial bud number and pattern in mouse urogenital sinus.[2]
- begins in fetal mice ductal progenitors (or buds) emerge from urogenital sinus epithelium
- prostatic buds develop in response to androgens, which activate androgen receptors in UGS mesenchyme
- two rows of 3-4 prostatic buds at birth
