Testosterone and androstenedione concentrations in human testis and epididymis during the first two years of life [PDF]

open access: yes, 1983
Testosterone and androstenedione were measured in testicular and epididymal tissue of 37 previously healthy infants between 1 and 24 months of age who died suddenly. In half of the patients elevated plasma levels of cortisol and androstenedione suggested

Different expression of B7-H3 in the caput, corpus, and cauda of the epididymis in mouse

open access: yesBMC Urology, 2017
Background B7-H3, a member of the B7 family of the Ig superfamily of proteins, has been detected in the epididymis, which is a storage organ related to sperm maturation.

An atlas of human proximal epididymis reveals cell-specific functions and distinct roles for CFTR

open access: yesLife Science Alliance, 2020
A coordinated process of maturation in the lumen of the epididymis is required for sperm to fertilize an egg. A single cell atlas of the human proximal epididymis reveals key cell-specific functions, regional specialization, and two roles for CFTR ...

β-defensins and the epididymis: contrasting influences of prenatal, postnatal, and adult scenarios

open access: yesAsian Journal of Andrology, 2016
β-defensins are components of host defense, with antimicrobial and pleiotropic immuno-modulatory properties. Research over the last 15 years has demonstrated abundant expression of a variety of β-defensins in the postnatal epididymis of different species.

Zika virus disrupts the barrier structure and Absorption/Secretion functions of the epididymis in mice.

open access: yesPLoS Neglected Tropical Diseases, 2021
Several studies have demonstrated that Zika virus (ZIKV) damages testis and leads to infertility in mice; however, the infection in the epididymis, another important organ of male reproductive health, has gained less attention.

The diagnostic accuracy of two human epididymis protein 4 (HE4) testing systems in combination with CA125 in the differential diagnosis of ovarian masses [PDF]

open access: yes, 2011
Background: Cancer antigen 125 (CA125) is the best known single tumor marker for ovarian cancer (OC). We investigated whether the additional information of the human epididymis protein 4 (HE4) improves diagnostic accuracy.

Testosterone regulation on quiescin sulfhydryl oxidase 2 synthesis in the epididymis

open access: yes, 2021
The epididymis is an androgen-responsive organ, whose structure and functions are modulated by the coordination between androgen and epididymal cues.

The Expression and Localization of ZO-1, Claudin 1, and Claudin 4 in the Pig Epididymis

open access: yesJournal of Animal Reproduction and Biotechnology, 2019
Tight junctions are constituents of the blood–epididymis barrier that play roles in regulating the unidirectional transcellular transport of ions, water, and solutes to maintain optimal conditions for sperm maturation and storage. Claudin 1 (Cldn1) and 4

Morphometric study and immunolocalization of androgen receptors in epididymis during postnatal development in d"man lamb reared under arid environment in algeria [PDF]

open access: yesKafkas Universitesi Veteriner Fakültesi Dergisi, 2017
The aim of this study was to examine the morphometry and the immunolocalization of androgen receptors in the epididymis of D"Man lamb during postnatal development. The epididymis was collected at the slaughtering lamb, aged of 2 to 5 month. The weight of

DOES EPIDIDYMAL LENGTH IN MEN WITH CONGENITAL BILATERAL ABSENCE OF THE VAS DEFERENS HAVE A CORRELATION WITH THE FERTILIZATION RATE OF EPIDIDYMAL SPERM RETRIEVED BY MICROPUNCTURE TECHNIQUE? [PDF]

open access: yes, 1996
1996-03-29To investigate whether the variable length of the epididymis in men with congenital bilateral absence of the vas deferens (CBAVD) might have a correlation with fertilization and pregnancy rates in in vitro fertilization (IVF) treatment, we ...
