Cellular geometry controls the efficiency of motile sperm aggregates [PDF]

arXiv, 2018
Teams of cooperating sperm have been found across several vertebrate and invertebrate species, ranging from sperm pairs to massive aggregates containing hundreds of cells. Although the biochemical mechanisms involved in the aggregation process are still unclear, it was found that aggregation can enhance the mobility of the cells, thus offering an ...

SpeHeatal: A Cluster-Enhanced Segmentation Method for Sperm Morphology Analysis [PDF]

arXiv
The accurate assessment of sperm morphology is crucial in andrological diagnostics, where the segmentation of sperm images presents significant challenges. Existing approaches frequently rely on large annotated datasets and often struggle with the segmentation of overlapping sperm and the presence of dye impurities.

Atopic Dermatitis in Childhood and Biomarkers of Male Reproductive Health: A Danish National Birth Cohort Study

JEADV Clinical Practice, EarlyView.
This study found no indication of an adverse effect of childhood atopic dermatitis on biomarkers of male reproductive health. On the contrary, we observed some indications of slightly higher sperm concentration and lower follicle‐stimulating hormone (FSH) and luteinizing hormone (LH).
