    Self-sperm induce resistance to the detrimental effects of sexual encounters with males in hermaphroditic nematodes

    Lauren N Booth et al.
    Nematode hermaphroditism has co-evolved with a self-sperm sensing mechanism that protects hermaphrodites from the detrimental effects of mating with males.

    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.

    Essential role for SUN5 in anchoring sperm head to the tail

    Yongliang Shang et al.
    SUN5 is essential for the tight junction between sperm head and the head-tail coupling apparatus, and is the main cause of human acephalic spermatozoa syndrome.

    Rheotaxis facilitates upstream navigation of mammalian sperm cells

    Vasily Kantsler et al.
    Mammalian sperm subject to shear flow swim in upstream spirals along the walls bounding such flows, thereby demonstrating a robust mechanism for upstream navigation to the ovum.

    CatSperĪ¶ regulates the structural continuity of sperm Ca2+ signaling domains and is required for normal fertility

    Jean-Ju Chung et al.
    A new component, CatSper zeta, is required for continuous alignment of the calcium channel along the sperm's tail and is crucial for normal sperm swimming behavior and fertility.

    Drosophila seminal sex peptide associates with rival as well as own sperm, providing SP function in polyandrous females

    Snigdha Misra, Mariana F Wolfner
    A seminal protein from a mating-male can bind sperm previously stored in his mate, providing direct benefits to the sperm from the prior male that mated with her.

    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.
