Control of sperm motility by pheromones. Ciliated sensory neurons (red) in the nose detect a balance between pheromones and food-derived cues. Sensory neurons send hormones to the female reproductive tract that convert fat precursors (green) into prostaglandins, which guide motile sperm (magenta) to the fertilization site (yellow). This mechanism enables C. elegans to modulate reproductive capacity in response to dynamic environments.
