Epididymis: Anatomy and histology Kenhu

Histology of testis & epididymis, 2. Histology of testis • Testis is covered by ---tunica vaginalis ----tunica albuginea ----tunica vasculosa • Tunica albuginea- is a thick white fibrous connective tissue—called capsule of testis • Deep to the capsule there is tunica vasculosa- which is a highly vascularised connective tissue Appendix of the epididymis, also epididymal appendix, is a benign structure thought to be derived from the mesonephric duct (or Wolffian duct). It should not be confused with appendix of the testis The body and tail of the epididymis are filled with the highly coiled duct of the epididymis. The epithelium is pseudostratified columnar with stereocilia; a thin muscular layer surrounds the epithelium. Spermatozoa are stored in the lumen of the duct. 400x, 200 Epididymis. Accessory sex organs in the male reproductive system, in addition to the prostate, include the seminal vesicles, preputial glands, ductus deferens, and penis. These tissues can exhibit direct and indirect (often hormonal) pleotrophic pathologic responses

To disentangle the contributions of the diverse cell types comprising any given region of the mouse epididymis, we used microfluidic single-cell barcoding (10X Chromium) and single-cell RNA-Seq (scRNA-Seq) to characterize gene expression in dissociated cells from the four anatomical regions - caput, corpus, cauda, and vas deferens (Figure 1A, Figure 1—figure supplement 1) Sperm granulomas occur when sperm is released into the interstitium through a rupture in the epithelial lining or when inflammatory cells gain access to the sperm within the ductular lumen. If there is rupture into the interstitium, the epididymal lining may repair itself and maintain sperm continuity through the epididymal duct Bitestikel (anatomiskt benämnd epididymis) är ett cirka 6 cm långt kraftigt vridet rör på utsidan av testikeln, där spermierna lagras och mognar under 13-14 dagar.

Epididymis histology The epididymal duct can be divided into four segments; the initial segment, head, body and tail. The ducts are surrounded by concentric layers of fibromuscular tissue, rich in smooth muscle cells with blood vessels and nerves in the adjacent supporting stroma

Epididymis - Yale Universit

Epididymis: Lined by pseudostratified epithelium with stereocilia. The epididymis is a site of sperm maturation (acquisition of potential for movement) and storage. Together with the efferent ductules the epididymis absorbs 90% of the seminiferous fluid. Circular muscle layers propel sperm by peristaltic contractions.

Vasectomy impacts epididymis histology in humans. Under these obstructive conditions, a decrease in epididymis epithelium height and an increase in intraluminal diameter are observed, especially in the distal/cauda segment (Flickinger et al., 1995; Legare et al., 2001). The epididymis transcriptome is also affected by vasectomy (Thimon et al. Testis and epididymis - Anatomy and histology. Efferent ducts: see micro images below ; Epididymis: .

We describe a case of orchiectomy for testicular germ cell neoplasm with a peculiar associated cribriform hyperplasia of the epididymis. The process, which we have termed epididymal cribriform hyperplasia (ECH), is tantalizingly akin to patterns of cribriform ductal carcinoma in situ of the female breast and is characterized by complex arcades and cellular bridges spanning dilated epididymal lumina histology of the epididymis in the fowl, guinea fowl , quail and duck.

Definition / general. Usually related to cystitis, prostatitis or urethritis that spreads through vas deferens or lymphatics. May cause testicular ischemia and necrosis, later scarring and infertility with preservation of Leydig cells and preserved sexual activity The epididymis is a single tubule that connects the efferent ductules to the vas deferens and plays important roles in sperm transit, maturation, and storage. The structure identifiable grossly as the epididymis contains the efferent ductules, the highly convoluted epididymal tubule, and the surrounding connective tissue Large bore ducts of the epididymis, some containing sperm. Pseudostratified epithelium of the epididymis, composed of basal and columnar cells. The latter display clumps of stereocilia.

Epididymis. A long, coiled tube that stores developing sperm (and contributes a small amount of seminal fluid). Has a ring of smooth muscle; gradually thickens as the epididymis transitions to the ductus deferens. Epithelial lining comprises As the origin of the male gamete and the major source of testosterone, the testis is the primary focus of interest in reproductive histopathology. Increasingly, the epididymis is recognized as more than a conduit for spermatozoa, with essential functions contributing to the full development of viable sperm. 2

Posts about EPIDIDYMIS written by G.CHAITANAYA KRISHN Alterations in histology of the epididymis as a consequence of long-term obstruction have been reported earlier. 7,8,9,10 Since similar findings have been reported in epididymal histology taken at the time of vasectomy reversal in males with high antisperm antibody titres 11 and in animals 12,13, it is possible that these changes result from cell mediated immune response The epithelium of the epididymis also contains mitotic basal cells .
