Binucleation of male accessory gland cells in the common bed bug Cimex lectularius

Abstract The insect male accessory gland (MAG) is an internal reproductive organ responsible for the synthesis and secretion of seminal fluid components, which play a pivotal role in the male reproductive strategy. In many species of insects, the effective ejaculation of the MAG products is essentia...
