Nematodes can be propagated easily in the lab--in part because hermaphrodites can reproduce by self-fertilization. However, genetic crosses and other experiments may require a large number of males. This video describes a method to enrich for male C. elegans.

Ceanorhabditis elegans is a powerful tool to help understand how organisms develop from a single cell into a vast interconnected array of functioning tissues. Early work in C. elegans traced the complete cell lineage and structure at the electron microscopy level, allowing researchers unprecedented insight into the connection between genes, development and disease. Appreciating the stereotyped development and reproductive program of C. elegans is essential to using this model organism to its...

Caenorhabditis elegans is a microscopic, soil-dwelling roundworm that has been powerfully used as a model organism since the early 1970’s. It was initially proposed as a model for developmental biology because of its invariant body plan, ease of genetic manipulation and low cost of maintenance. Since then C. elegans has rapidly grown in popularity and is now utilized in numerous research endeavors, from studying the forces at work during locomotion to studies of neural circuitry.

FAQs
X-chromosome dosage provides a central input into the regulatory pathways that determine sexual development. Individuals with a single X chromosome develop as males, while XX individuals develop as self-fertilizing hermaphrodites. This relationship allows researchers to connect chromosome complement with developmental outcomes and to examine how regulatory signals produce distinct reproductive forms within one model species.
C. elegans males produce sperm and seek hermaphrodites for mating, whereas hermaphrodites can self-fertilize. Male reproduction therefore depends on locating a partner and successfully mating, making behavior and fertility important components of male biology. These differences provide a system for examining how reproductive roles are associated with anatomy, behavior, and sex-specific physiology.
Examining gene function specifically in males reveals biological effects that may not be apparent in hermaphrodites. Researchers can relate male-specific activity to reproduction, mating behavior, development, or physiology, then compare those outcomes with other sexual forms. This approach helps clarify how biological sex shapes gene action and contributes to differences in organismal traits.
Males enable cross-fertilization with hermaphrodites, allowing researchers to combine or maintain distinct genetic backgrounds through mating. This reproductive role is especially useful when investigators need offspring that reflect genetic contributions from different parents rather than hermaphrodite self-fertilization alone. The resulting crosses support studies of inheritance, genetic variation, and the relationship between genotype and phenotype.
Studies may focus on male anatomy, mating behavior, fertility, and sex-specific gene function. These traits provide complementary information: anatomy addresses physical reproductive features, behavior examines partner location and mating, and fertility assesses reproductive success. Together, such observations help connect male structure and actions with genetic regulation, development, and reproductive outcomes.
Male-focused research in C. elegans contributes to investigations of reproductive biology, neural circuits, evolution, and sex-specific development and physiology. Mating behavior offers a context for studying nervous-system function, while differences between males and hermaphrodites provide comparisons for understanding sex-biased biology. The model therefore links reproductive observations with broader questions about how biological sex influences organisms.
