sentences:  Traumatic insemination allows subsequent males to bypass the female's plugged genital tract, and inject sperm directly into her circulatory system.Others have argued that the practice of traumatic insemination may have been an adaptation for males to circumvent female resistance to mating to eliminate courtship time, allowing one male to inseminate many mates when contact between them is brief; or that it evolved as a new development in the sperm competition as a means to deposit sperm as close to the ovaries as possible.This bizarre method of insemination probably evolved as male bed bugs competed with each other to place their sperm closer and closer to the mother lode of eggs, the ovaries.
