A urogenital sinus anomaly is also a rare birth defect in women where the urethra and vagina both open into a common channel. [ 3 ] [ 4 ] A persistent cloaca is a disorder where the rectum , vagina , and urinary tract meet and fuse, creating a cloaca , a single common channel.

m, m. Right and left Müllerian ducts uniting together and running with the Wolffian ducts in gc, the genital cord: m. Müllerian duct, the upper part of which remains as the hydatid of Morgagni; the lower part, represented by a dotted line descending to the prostatic utricle, constitutes the occasionally existing cornu and tube of the uterus ...
The part of the urogenital sinus related to the bladder and urethra absorbs the ends of the Wolffian ducts and the associated ends of the renal diverticula. This gives rise to the trigone of the bladder and part of the prostatic urethra. The remainder of this part of the urogenital sinus forms the body of the bladder and part of the prostatic ...
Bulbourethral glands are located posterior and lateral to the membranous portion of the urethra at the base of the penis, between the two layers of the fascia of the urogenital diaphragm, in the deep perineal pouch. They are enclosed by transverse fibers of the sphincter urethrae membranaceae muscle.
The female reproductive system is composed of two embryological segments: the urogenital sinus and the paramesonephric ducts. The two are conjoined at the sinus tubercle. [2] [3] Paramesonephric ducts are present on the embryo of both sexes. [3] [4] Only in females do they develop into reproductive organs.

The prostate forms from the urogenital sinus and the efferent ducts form from the mesonephric tubules. For this, it is critical that the ducts are exposed to testosterone during embryogenesis. Testosterone binds to and activates androgen receptor, affecting intracellular signals and modifying the expression of numerous genes. [3]
