Introduction: Usually, patients with sY84 or sY86 deficiency present with azoospermia, but recent studies have shown that some males with partial AZFa deletions, including sY84 or sY86, exhibit normal fertility. Here, we reported a rare case of AZF deletion in a family, where both father and son exhibited a deletion at the sY86 site in the AZFa region and a partial deletion in the AZFc region.
Methods And Results: Detection was performed using classical multiplex polymerase chain reaction and the "Male AZF Full-region Detection" Panel, revealing specific deletions in AZFa: Yq11.
Synthetic alleles to study MUTE-dependent molecular transitions in stomatal development.

Stomatal abundance sets plants' potential for gas exchange, impacting photosynthesis and transpiration and, thus, plant survival and growth. Stomata originate from cell lineages initiated by asymmetric divisions of protodermal cells, producing meristemoids that develop into guard cell pairs. The transcription factors SPEECHLESS, MUTE, and FAMA are essential for stomatal lineage development, sequentially driving cell division and differentiation events.

We addressed genomic prediction accounting for partial correlation of marker effects, which entails the estimation of the partial correlation network/graph (PCN) and the precision matrix of an unobservable m-dimensional random variable. To this end, we developed a set of statistical models and methods by extending the canonical model selection problem in Gaussian concentration, and directed acyclic graph models. Our frequentist formulations combined existing methods with the EM algorithm and were termed Glasso-EM, Concord-EM and CSCS-EM, whereas our Bayesian formulations corresponded to hierarchical models termed Bayes G-Sel and Bayes DAG-Sel.

A 35-year-old man visited a local doctor for continuing analysis of his infertility. Semen analysis revealed azoospermia while an ultrasonography detected a right testicular tumor with a diameter of 10 mm. A blood test was negative for tumor markers.

Fluoxetine, a widely used selective serotonin reuptake inhibitor (SSRI), is highly effective in treating psychiatric disorders such as depression. Recently, its potential negative impact on male reproductive function has recently raised concerns, but it remains unknown whether testicular damage from long-term fluoxetine exposure can recover after stopping the drug. In this study, male C57BL/6 mice were divided into control (saline) and treatment (fluoxetine, 20mg/kg.
