Sterile sperm castes are widespread, but their significance remains enigmatic. New experiments on Drosophila pseudoobscura reveal that sterile sperm may promote the survival of fertilising sperm inside the spermicidal female reproductive tract.
不育精子类型广泛存在，但其意义仍不明确。对伪黑腹果蝇的新实验表明，不育精子可能会促进有受精能力的精子在具有杀精作用的雌性生殖道内的存活。
