Asian Journal of Andrology, 2015 One of the most common lesions present in the spermatozoa of human infertility patients is an idiopathic failure of sperm-egg recognition. Although this unique cellular interaction can now be readily by-passed by assisted reproductive strategies such as ...

Transcriptional Inhibition of lncRNA gadd7 by CRISPR/dCas9-KRAB Protects Spermatocyte Viability
Frontiers in Molecular Biosciences, 2021 Our previous study found that lncRNA gadd7 was up-regulated in the semen of varicocele patients, and could promote the apoptosis of mouse spermatocytes and inhibit their proliferation.

Heat Stress in Quail: Impacts on Health and Productivity, and Mitigation Strategies
Animal Research and One Health, EarlyView.Heat stress disrupts physiological homeostasis in quail, inducing oxidative stress, immune dysregulation, and metabolic imbalance, which impair growth, reproduction, product quality, and welfare. Integrating nutritional, environmental, and genetic–epigenetic strategies enhances thermotolerance, sustains productivity, and supports climate‐smart quail ...

A comparative evaluation of semen parameters in pre- and post-Hurricane Katrina human population
Asian Journal of Andrology, 2015 A natural disaster leading to accumulation of environmental contaminants may have substantial effects on the male reproductive system. Our aim was to compare and assess semen parameters in a normospermic population residing in the Southern Louisiana, USA

Varicocele and testicular function
Asian Journal of Andrology, 2015 Testicular varicocele, a dilation of the veins of the pampiniform plexus thought to increase testicular temperature via venous congestion, is commonly associated with male infertility.

A Caenorhabditis elegans protein with a PRDM9-like SET domain localizes to chromatin-associated foci and promotes spermatocyte gene expression, sperm production and fertility. [PDF]
PLoS Genetics, 2018 To better understand the tissue-specific regulation of chromatin state in cell-fate determination and animal development, we defined the tissue-specific expression of all 36 C.

Biological Reviews, EarlyView.ABSTRACT Heat stress (HS) is an increasing threat to male reproductive health, disrupting spermatogenesis through complex and interdependent cellular responses within the seminiferous epithelium. Although excessive reactive oxygen species (ROS) production is a hallmark of HS, ROS also act as central regulators of cell fate decisions beyond their role ...

Cytofluorometric analysis of spermatocytic seminoma [PDF]
Cancer, 1993 Whether spermatocytic seminoma (SS) develops during meiosis or not is still controversial. To determine that, the DNA content of large, small, and intermediate cells of SS was measured by cytofluorometry to obtain DNA histograms for each cell type. The large cells were aneuploid and showed cell cycles with G0/G1 DNA values from 3C to 18C. The ploidy of
