Mates of CG9997^{dsRNA.Sym.Scer\UAS} Scer\GAL4^αTub84B.PL males show no difference in conformational stage distribution when compared to mates of control males.

In defensive sperm competition, assessed with a second mating on the third day after the initial mating, mates of CG9997^{dsRNA.Sym.Scer\UAS} Scer\GAL4^αTub84B.PL knockdown males sire a higher proportion of progeny than do control siblings.

Males depleted for CG9997, through expression of CG9997^{dsRNA.Sym.Scer\UAS} under the control of Scer\GAL4^αTub84B.PL, do not significantly differ from controls in the overall number of eggs laid.

Males depleted for CG9997, through expression of CG9997^{dsRNA.Sym.Scer\UAS} under the control of Scer\GAL4^αTub84B.PL, do not stimulate full egg laying in their mates. However, from days 2-10 after the start of mating, the number of eggs laid by the mates of CG9997^{dsRNA.Sym.Scer\UAS}-Scer\GAL4^αTub84B.PL males is reduced significantly compared to controls. Consistent with the reduced egg laying, females mated to CG9997^{dsRNA.Sym.Scer\UAS} flies exhibit significantly lower fertility compared to controls.

Females mated to CG9997^{dsRNA.Sym.Scer\UAS}-Scer\GAL4^αTub84B.PL males show low receptivity to re-mating 24 hours after the initial mating. At 4 days after the start of mating, mates of CG9997 knockdown males are significantly more receptive to mating than controls.

Females mated to CG9997^{dsRNA.Sym.Scer\UAS}-Scer\GAL4^αTub84B.PL males do not differ significantly in the number of sperm in storage at 2 hours after the start of mating. However, at four days after the start of mating, females mated to CG9997^{dsRNA.Sym.Scer\UAS}-Scer\GAL4^αTub84B.PL knockdown males have significantly more sperm stored in the seminal receptacle when compared to controls. By ten days after the start of mating, females mated to CG9997^{dsRNA.Sym.Scer\UAS}-Scer\GAL4^αTub84B.PL knockdown males, have significantly more sperm stored in their seminal receptacle compared to controls.
