Cockroaches reproduce in two ways: sexual reproduction and parthenogenesis  When cockroach females live in groups consisting entirely of females, parthenogenesis occurs and eggs are laid earlier  The researchers tested the effects of cockroach sex and estrogen on parthenogenesis through experiments  First, a female cockroach was kept together with a castrated male cockroach, and it was found that the timing of the female cockroach laying eggs did not change; then, the males were provided with estrogen on a regular basis, causing them to live in female groups
False, but their spawning time is not advanced either
Pure female group living accelerates cockroach reproduction
