Introduction
In humans, the male accessory glands are the seminal vesicles, prostate gland, and the bulbourethral glands. The male gonad, the testis, differentiates embryonically initially under the influence of the Y chromosome. Later under the influence the gonad-derived fetal testosterone acting through androgen receptors, a region of the urogenital sinus (UGS) mesenchyme differentiates to form the primordial prostate buds. The buds then signal back to the overlying epithelium, inducing duct formation, this was one of the early studied (1970's) example of an mesenchymal-epithelial interaction in development. Interestingly, the female equivalent gland originally called Skene's gland, then paraurethral gland has now also been renamed the female prostate.
There are also currently separate pages describing Genital - Male Development | Spermatozoa Development | Testis Development | Prostate Development.

Genital Development Overview
Three main stages during development, mesonephric/paramesonephric duct changes are one of the first male/female differences that occur in development, while external genitaila remain indeterminate in appearance for quite a while.

Pages where the terms "Historic" (textbooks, papers, people, recommendations) appear on this site, and sections within pages where this disclaimer appears, indicate that the content and scientific understanding are specific to the time of publication. This means that while some scientific descriptions are still accurate, the terminology and interpretation of the developmental mechanisms reflect the understanding at the time of original publication and those of the preceding periods, these terms, interpretations and recommendations may not reflect our current scientific understanding.
