Bioelectronic transducing surfaces that are nanometric in size have been the main route to
detect single molecules. Though enabling the study of rarer events, such methodologies are …

Sperm motility is linked to the activation of signaling pathways that trigger movement. These
pathways are mainly dependent on Ca2+, which acts as a secondary messenger. The …

In mammals, fertilization occurs via a comprehensive progression of events. Freshly
ejaculated sperm have yet to acquire progressive motility or fertilization ability. They must …

The lifespan of spermatozoa from externally fertilizing freshwater fish ranges from a few
seconds to several minutes, depending on the species. External factors, such as …

Fish spermatozoa acquire potential for motility in the sperm duct where they are immotile.
Osmolality of the seminal plasma is a key factor to maintain spermatozoa in the quiescent …

Navigation of sperm in fluid flow, called rheotaxis, provides long‐range guidance in the
mammalian oviduct. The rotation of sperm around their longitudinal axis (rolling) promotes …

Voltage-sensing (VSD) and cyclic nucleotide-binding domains (CNBD) gate ion channels for
rapid electrical signaling. By contrast, solute carriers (SLCs) that passively redistribute …

Background and Purpose Sperm from many species share the sperm‐specific Ca2+
channel CatSper that controls the intracellular Ca2+ concentration and, thereby, the …

The biology of fish sperm, an important topic in the research of reproduction and fisheries
from basic science to evolutionary and applied aspects, has implications for aquaculture …

The mechanisms underlying sex determination are astonishingly plastic. Particularly the
triggers for the molecular machinery, which recalls either the male or female developmental …
