The insemination capacity of Aedes aegypti males is essentially determined by the time the males reach sexual maturity. Although meiosis and spermiohistogenesis may still be observed in 5 to 10-day-old males, the sperm production in the adult is insufficient to replace the sperm lost in successful copulations. The average male can provide 4–5 females with sufficient sperm for their whole lifetime and simultaneously make them refractory to further insemination. Smaller amounts of sperm ran be transmitted to 2–4 additional females. For A. aegypti the question about permanence of induced sterility should become irrelevant if the sterilization takes place in sexually mature males.
