Background: As the COVID-19 pandemic nears resolution in 2024, the mechanisms by which SARS-CoV-2 and other viral infections induce spermatogenic dysfunction remain poorly understood. This review examines the mechanisms by which viral infections, particularly COVID-19, disrupt spermatogenesis and highlights the implications for male reproductive health. While reports suggest that spermatogenic dysfunction caused by COVID-19 is mild and transient, these findings may have broader applications in understanding and treating spermatogenic dysfunction caused by future viral infections.

Cells that collide with each other repolarize away from contact, in a process called contact inhibition of locomotion (CIL), which is necessary for correct development of the embryo. CIL can occur even when cells make a micron-scale contact with a neighbor-much smaller than their size. How precisely can a cell sense cell-cell contact and repolarize in the correct direction? What factors control whether a cell recognizes it has contacted a neighbor? We propose a theoretical model for the limits of CIL where cells recognize the presence of another cell by binding the protein ephrin with the Eph receptor.

As a person nears the end of their life, culture and ethnicity increasingly drive preferences and priorities for care. Understanding these preferences and priorities is fundamental to health care professionals' goals to respect decision making and support the individual throughout this phase of life. Across Africa, several countries are in the initial stages of implementing palliative care services in their burgeoning health care systems.
