We studied the location of a membrane-bound carbonic anhydrase (CA IV) in the human male reproductive tract using a specific antiserum to human CA IV in conjunction with immunoblotting, immunoperoxidase, and immunofluorescence techniques. The microvilli and apical plasma membrane of the epithelial cells and the subepithelial smooth muscle layer of the epididymis, ductus deferens, and ampulla of the ductus deferens showed specific staining for CA IV. The epithelial cells of the prostate and seminal vesicle failed to stain for CA IV, however, whereas the subepithelial smooth muscle layer showed positive staining. No specific staining for CA II was seen in the epithelium of the epididymal duct or the proximal ductus deferens. The presence of CA IV in the epididymis was confirmed by immunoblotting, which revealed 35 KD and 33 KD polypeptides. The results show that the microvilli and the apical plasma membrane of the lining epithelium of the epididymal duct, ductus deferens, and ampulla of the ductus deferens contain the membrane-bound carbonic anhydrase isoenzyme IV. The presence of the enzyme in the epithelium of the epididymis and ductus deferens is probably linked to the acidification of the epididymal fluid that prevents premature sperm activation. Its physiological role in the smooth muscle cells remains to be elucidated.

Viral Interactions

Sexual transmission of Zika virus (ZIKV) is a matter of great concern. Infectious viral particles can be shed in semen for as long as six months after infection and can be transferred to male and female sexual partners during unprotected sexual intercourse. The virus can be found inside spermatozoa and could be directly transferred to the oocyte during fertilization. Sexual transmission of ZIKV can contribute to the rise in number of infected individuals in endemic areas as well as in countries where the mosquito vector does not thrive. There is also the possibility, as has been demonstrated in mouse models, that the vaginal deposition of ZIKV particles present in semen could lead to congenital syndrome. In this paper, we review the current literature to understand ZIKV trafficking from the bloodstream to the human male reproductive tract and viral interactions with host cells in interstitial spaces, tubule walls, annexed glands and semen. We hope to highlight gaps to be filled by future research and potential routes for vaccine and antiviral development.

In the present study authors had separated testis, epididymis-caput, corpus, cauda, vas deferens, seminal vesicle, prostate gland and bulbourethral gland from human male reproductive tract, made it to ash form. Semen also underwent same procedure. All samples had undergone X-ray diffraction analysis. Results Results showed there where two distinct rings for each sample. We named it is “A” &” B”. Under “A” Barium silicate, Barium silicate hydrate and three metal complexes of copper, gold and zinc were seen. Under “B” Calcium silicate and calcium silicate hydrate were observed. Both “A” and “B” were seen throughout the length (expect for “A” is seminal vesicle) and in semen. Conclusions A tri metal complex of copper, gold and zinc is reported in this study, is first of its kind in Biology.

Triatoma Rubrofasciata

AbstractThe male reproductive tract in Triatominae has a pair of testes, two vasa deferentia, a pair of seminal vesicles, four pairs of accessory glands, and an ejaculatory duct, which opens in the aedeagus. In species of the genus Triatoma each testis is formed by seven testicular follicles. Because Triatoma rubrofasciata has a common ancestor with species of Triatoma occurring in North America and because the length of testis follicles varies among different species of Triatoma a morphometrical analysis of the follicles was conducted. Triatoma rubrofasciata has seven testis follicles of variable length that are similar between left and right testes. The statistics allowed the classification in a long follicle, two medium follicles, two that are short, and two that are very short. This finding is compared with data available for other Triatominae and it is emphasized that the length of follicles testis should be included in future phylogenetic analysis of Triatominae.
