    Neuropeptide B mediates female sexual receptivity in medaka fish, acting in a female-specific but reversible manner

    Towako Hiraki-Kajiyama et al.
    In the brain of medaka fish, neuropeptide B acts directly downstream of estrogen in a female-specific but reversible manner to mediate female receptivity to male courtship.

    Introduction of a male-harming mitochondrial haplotype via ‘Trojan Females’ achieves population suppression in fruit flies

    Jonci Nikolai Wolff et al.
    Mitochondrial genomes harbor male-fertility-reducing mutations that can be harnessed to control population viability as a novel approach to control economic and environmental pests.

    Neuropeptide F regulates courtship in Drosophila through a male-specific neuronal circuit

    Weiwei Liu et al.
    Functional dissection of a cluster of male-specific neurons in Drosophila reveals a neuronal circuit regulating male courtship in accordance with the internal drive state.

    A case study for a psychographic-behavioral segmentation approach for targeted demand generation in voluntary medical male circumcision

    Sema K Sgaier et al.
    A novel, hybrid segmentation technique reveals human heterogeneity in barriers towards a behavior, and is applied to characterize distinct segments in voluntary medical male circumcision.

    Mating and male pheromone kill Caenorhabditis males through distinct mechanisms

    Cheng Shi et al.
    Male C. elegans die through two distinct mechanisms – mating-induced germline activation, and potent male pheromone toxicity – but the latter is unique to males of androdioecious species (made up of hermaphrodites and males).

    A mitochondrial DNA hypomorph of cytochrome oxidase specifically impairs male fertility in Drosophila melanogaster

    Maulik R Patel et al.
    A 'male-harming' mtDNA mutation has been identified in Drosophila and impairs male fertility without impairing other male or female functions.
    1. Neuroscience

    Caenorhabditis elegans male sensory-motor neurons and dopaminergic support cells couple ejaculation and post-ejaculatory behaviors

    Brigitte LeBoeuf et al.
    In nematode worms, the length of the male refractory period–the time between matings–is regulated by multiple transmitters including dopamine, which both promotes ejaculation and reduces the activity of males post-copulation.

    The yellow gene influences Drosophila male mating success through sex comb melanization

    Jonathan H Massey et al.
    Melanization of a secondary sexual structure facilitates male mating success in Drosophila.

    Successful transmission and transcriptional deployment of a human chromosome via mouse male meiosis

    Christina Ernst et al.
    Transmission of an entire human chromosome through the mouse male germline reveals an unexpectedly high tolerance of aneuploidy during male meiosis and results in accurate transcriptional deployment despite massive epigenetic remodeling during spermatogenesis.

    Male meiotic spindle features that efficiently segregate paired and lagging chromosomes

    Gunar Fabig et al.
    Chromosome segregation in male spermatocytes exhibits anaphase A without shortening of autosome-associated microtubules and partitioning of an unpaired X chromosome that is initiated by an imbalance of attached kinetochore microtubules.
