The epididymis is present in male reptiles, birds, mammals, and cartilaginous fish. [1] The caput epididymidis is fused to the testis in eutherian mammals, but not in marsupials. [13] In reptiles, there is an additional canal between the testis and the head of the epididymis and which receives the various efferent ducts.
Embryos are formed with Wolffian and Mullerian ducts, which will either become the male or female reproductive tract, respectively. [8] In a male embryo, the testicular cords will induce the development of the Wolffian duct into the vas deferens, epididymis and the seminal vesicle and cause the repression and regression of the Mullerian duct.

The human female reproductive system is made up of the internal and external sex organs that function in the reproduction of new offspring. The reproductive system is immature at birth and develops at puberty to be able to release matured ova from the ovaries , facilitate their fertilization , and create a protective environment for the ...
The mediastinum testis is a thick yet incomplete septum at the posterior part of the testis formed by the tunica albuginea of testis projecting into the testis at its posterior aspect where the testis is not lined by the serous membrane to allow for the attachment of the epididymis.
The testicle in the male and the ovary in the female are called the primary sex organs. [1] All other sex-related organs are known as secondary sex organs . The outer parts are known as the genitals or external genitalia , visible at birth in both sexes, [ 1 ] while the inner parts are referred to as internal genitalia , which in both sexes ...

The human female reproductive system contains three main parts: the vagina, which leads from the vulva , the vaginal opening, to the uterus; the uterus , which ...
During the changes associated with the descent of the testes, this scrotal area is drawn out to form the scrotal sacs. The penis is developed from the phallus. As in the female, the urogenital membrane undergoes absorption, forming a channel on the under surface of the phallus; this channel extends only as far forward as the corona glandis.
