Question

The Wolffian duct gives rise to
A. Scrotum
B. Labia majora
C. Both A and B
D. Epididymis

Answer 1

Hint: The Wolffian tube is the paired embryogenic tubules that drain the mesonephros (primitive kidney) to the cloaca. It is also called the mesonephric duct. It differentiates into sex organs.

Step by step answer:The development of the reproductive organs or sex organs is the part of prenatal development. Their development occurs together with the development of the urinary system. The development of these organs is often described together.
During embryonic development, the mesonephric duct is exposed to the male hormone testosterone
which leads to male sexual differentiation. The Wolffian duct differentiates into the tube of the
epididymis, the ductus deferens, and the ejaculatory duct. The seminal vesicle arises later. It formed
during the third month of foetal development. During embryonic development, a large part of the head
of the mesonephric duct disappears and the remaining part forms the efferent ducts of the testis while
the posterior tubules are represented by the ductuli aberrantes and paradidymis that can be seen in
front of the spermatic cord above the head of the epididymis.
In females, the Wolffian duct gradually degenerates in the absence of testosterone. In females, Mullerian
ducts develop. These ducts persist and undergo further development. The portions that lie in the genital
cord fuse to form the uterus and vagina.
Thus, Option D. Epididymis is the correct answer.

Note: The Wolffian duct or mesonephric duct, develops into the rete testis, the ejaculatory ducts, the epididymis, the ductus deferens, and the seminal vesicles. The prostate is formed separately from the urogenital. In females, the Mullerian duct forms sex organs.
