Myosin VI Is Associated With the Endoplasmic Reticulum in Regions of Sertoli Cells Containing Tubulobulbar Complexes

open access: yesCytoskeleton, EarlyView.
ABSTRACT Myosin VI has been reported by others to localize in association with various regions of apical tubulobulbar complexes (TBCs) at sites of attachment between Sertoli cells and late spermatids in the mouse. Tubulobulbar complexes internalize “intact” intercellular junctions during sperm release and during spermatocyte translocation through the ...

Improving Human Sperm Head Morphology Classification with Unsupervised Anatomical Feature Distillation [PDF]

open access: yesarXiv, 2022
With rising male infertility, sperm head morphology classification becomes critical for accurate and timely clinical diagnosis. Recent deep learning (DL) morphology analysis methods achieve promising benchmark results, but leave performance and robustness on the table by relying on limited and possibly noisy class labels.

Immature germ cells in semen – correlation with total sperm count and sperm motility

open access: yesJournal of Cytology, 2013
Background: Current data regarding infertility suggests that male factor contributes up to 30% of the total cases of infertility. Semen analysis reveals the presence of spermatozoa as well as a number of non-sperm cells, presently being mentioned in ...

Sexual revolution and sperm count [PDF]

open access: yesBMJ, 1994
EDITOR, - Together with other discoveries, the findings of Carlsen et al that the quality of semen has been declining over the past 50 years1 have led to disturbing speculation about the world's environment. I think, however, that the relation of their findings to such speculation is scientifically untenable.

The Heterotaxy Gene CCDC11 Is Important for Cytokinesis via RhoA Regulation

open access: yesCytoskeleton, EarlyView.
ABSTRACT Mutations in CCDC11 (cfap53) have been identified in multiple patients with heterotaxy (Htx), a disorder of left–right (LR) patterning of the internal organs. In Xenopus, depletion of Ccdc11 causes defects in LR patterning, recapitulating the patient phenotype. Upon Ccdc11 depletion, monociliated cells of the Left–Right Organizer (LRO) exhibit

Protective effects of Camellia sinensis on Syzygium aromaticum- or chlorpyrifos-induced reproductive toxicity in male Wistar rats

open access: yesJournal of Basic and Applied Zoology, 2019
Background The potential toxicity of clove, Syzygium aromaticum, notwithstanding its beneficial health effect to human health remains a critical issue. Purpose This study was designed to assess the effects of oil extracts of clove (S.

Sperm death and dumping in Drosophila [PDF]

open access: yes, 2004
Mating with more than one male is the norm for females of many species. In addition to generating competition between the ejaculates of different males, multiple mating may allow females to bias sperm use.
