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.
WAP four-disulfide core domain protein 2 - also known as Human Epididymis Protein 4 [5] (HE4) - is a protein that in humans is encoded by the WFDC2 gene. [ 6 ] [ 7 ] [ 8 ] HE4 is a tumor marker of ovarian cancer , with 80% sensitivity at a cut-off of 150 pmol/L. [ 9 ]
The spermatic cord is the cord-like structure in males formed by the vas deferens (ductus deferens) and surrounding tissue that runs from the deep inguinal ring down to each testicle.
The epididymis is a long whitish mass of tightly coiled tube. The sperm that are produced in the seminiferous tubules flow into the epididymis. During passage via the epididymis, the sperm undergo maturation and are concentrated by the action of ion channels located on the apical membrane of the epididymis. [2]
The epididymis is inspected and an individual tubule is selected to enter and connect to the vas deferens. From this point on, one of two epididymovasostomy techniques is taken. In the mucosa -to-mucosa, end to side method, [ 1 ] an opened epididymal tubule is connected to the cut end of the vas deferens with 4 to 6 small (10-0) simple sutures ...
The development of the reproductive system is the part of embryonic growth that results in the sex organs and contributes to sexual differentiation. Due to its large overlap with development of the urinary system , the two systems are typically described together as the genitourinary system .
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 human female reproductive system is a series of organs primarily located inside of the body and around the pelvic region of a female that contribute towards the reproductive process. The human female reproductive system contains three main parts: the vulva , which leads to the vagina, the vaginal opening, to the uterus; the uterus , which ...
