Comparison of Murine Epididymal and Seminal Vesicle Proteinase Inhibitors.
… This journey begins with sperm production in the seminiferous tubules of the testes.

Avaliação testicular e seminal de caprinos alimentados com feno de Cenostigma pyramidale (tul.) E. Gagnon & g. P. Lewis
… the gonadosomatic index, the diameter of the seminiferous tubules, the height of the germinal epithelium, volumetric proportion and volume of the testicular parenchyma components; total length of the seminiferous tubules, seminiferous tubule length per gram of testis, leydigosomatic and …

Innervation des Cervidenhodens
… the developmental and functional state of the seminiferous tubules. Small testes with solid and narrow tubules, as seen in the prepuberal phase and during seasonal reproductive quiescence, are better innervated than large testes with expanded and spermatogenetically active seminiferous tubules.

Pengaruh infusa daun murbei (Morus alba L.) terhadap gambaran histologi dan berat testis tikus putih (Rattus norvegicus) diabetes mellitus kronik
… spermatozoa), Sertoli cells, the diameter of the seminiferous tubules, and testes weight. Data were analyzed with One Way ANOVA, if there is a very real difference then followed by further test Duncan α 1%. The results showed that the infusion of leaves of mulberry (Morusalba L.) affectedon …

Investigating the Effects of Vinclozolin on Reproduction in Three Generations of Sigmodon Hispidus
… levels were compared. Sperm production in the seminiferous tubules of the testes (collected during necropsy, embedded, sectioned, and placed on slides for examination) allowed a sperm index for comparison. Other comparisons included body mass on days 2, 14, 30, 45, 60, and 75. Additional …

Correlative Analysis of Sperm Morphology, Seminiferous Epithelial Area and Testis Weight in the Boar
… to result in decreased fertility. In each group, seminiferous epithelial area (SEA) was taken by digitizing 50 seminiferous tubules per testis. Also, different degrees of histologic changes were determined for each testis from the same tissue sections. Testicular spermiostasis was examined macro …

A comprehensive survey of somatic mutation landscapes in normal human cells
… and across tissue types, with the lowest in the seminiferous tubules and the highest in liver hepatocytes. Interestingly, post-mitotic cells such as the heart, cerebellum, skeletal muscle, and adipose tissue accumulate somatic mutations at a rate similar to that of their actively dividing …

Multi-cycle cisplatin treatment alters spermatogonial functional stem cell behavior and niche
… are theoretically capable of repopulating the seminiferous tubules after exposure has ceased. It is proposed that an altered spermatogonial environment during recovery from the initial treatment cycle may drive an increase in SSC mitotic cell activity, rendering the SSC pool increasingly …

Rat angiotensin-converting enzyme : tissue specific expression during pharmacological inhibition
… markedly induced to produce ACE, as was ACE in seminiferous tubules. ACE induction was also noted in the expected sites of renal tubular epithelium and glomerular tissue. Interestingly, ACE expression was also enhanced in cardiac valves. In these studies it has been conclusively demonstrated …

Neural and endocrine control of mating behavior in selected mating lines of chickens and quail
… a significant increase in the diameter of the seminiferous tubules relative to vehicle controls. In an attempt to increase the accuracy of stereotaxic surgery, the spatial relationships between several external cranial landmarks and brain nuclei were established. The data were employed to …

The role of conexin 43 in murine sertoli cell development
… the only somatic cell type present within the seminiferous tubules of the testis. The support of these somatic cells is essential for testis formation and spermatogenesis. They are called mother or nurse cells, implicating their intimate association with germ cells and also their central role …
