Prostatic utricle

Prostatic utricle (utriculus prostaticus) is a small, tubular structure located in the prostate gland of the male reproductive system. It is also known as the uterus masculinus due to its embryological resemblance to the female uterus.

Etymology

The term prostatic utricle is derived from the Latin words prostata meaning prostate, and utriculus meaning small bag. The term uterus masculinus is derived from the Latin uterus meaning womb, and masculinus meaning male.

Anatomy

The prostatic utricle is situated in the prostate gland, which is located below the bladder and in front of the rectum. It is a small, blind-ended pouch that extends from the prostatic urethra at the point of the seminal colliculus. The length of the prostatic utricle varies, but it is typically around 6 mm long.

Development

The prostatic utricle develops from the Müllerian ducts, which are structures present during the embryonic development of the reproductive system. In males, the Müllerian ducts typically regress due to the influence of anti-Müllerian hormone. However, a small portion of the ducts may persist and form the prostatic utricle.

Clinical significance

The prostatic utricle may be associated with certain medical conditions. For instance, an enlarged prostatic utricle may be seen in cases of congenital adrenal hyperplasia or intersex conditions. It may also be associated with urinary tract infections or prostatic inflammation.
