    Sperm competition risk drives rapid ejaculate adjustments mediated by seminal fluid

    Michael J Bartlett et al.
    Seminal fluid harbours the as yet unknown mechanism that facilitates rapid adjustment of sperm velocity in response to changing sperm competition risk.

    Sperm competition: The need for speed

    Tom Pizzari
    A change in social status can quickly lead to a change in the quality of the seminal fluid produced by a male Chinook salmon as he responds to increased reproductive competition from higher-status males.

    BiteOscope, an open platform to study mosquito biting behavior

    Felix JH Hol et al.
    A new tool to visualize blood-feeding mosquitoes in high resolution and quantitatively characterize their behavior sheds light on contact-dependent sensing and blood-feeding dynamics of several medically relevant mosquito species.

    A common 1.6 mb Y-chromosomal inversion predisposes to subsequent deletions and severe spermatogenic failure in humans

    Pille Hallast et al.
    In addition to its academic merits, characterizing the genetic determinants of male (in)fertility and identifying clinically actionable genetic variants can lead to improved diagnosis or even treatment of such conditions.

    TRPV4 is the temperature-sensitive ion channel of human sperm

    Nadine Mundt et al.
    The molecular identity of the temperature-sensitive ion channel of human sperm that ensures depolarization is TRPV4.

    DNA methylation and gene expression changes derived from assisted reproductive technologies can be decreased by reproductive fluids

    Sebastian Canovas et al.
    Reproductive fluids help the correct establishment of some epigenetic marks and gene expression in preimplantation pig embryos.

    COMP-1 promotes competitive advantage of nematode sperm

    Jody M Hansen et al.
    Nematode sperm respond to competitive environments by modulating cellular pathways involved in migration and storage to ensure their access to oocytes.

    SIR-2.1 integrates metabolic homeostasis with the reproductive neuromuscular excitability in early aging male Caenorhabditis elegans

    Xiaoyan Guo, L René García
    A protein called SIR-2.1 helps to protect worms from the effects of aging by regulating metabolic processes that would otherwise generate damaging reactive oxygen species.
