The spermatozoa are embeded in a extracellalar matrix composed of high dense fibrils matrix and flocculent and concentric vesicles similar to that in the primary spermatophore layer, but the later lack of spermotozoa. The flocculent and concentric vesicles are often seen to release their contents around the main body of spermatozoa. The spermatozoa may absorb the contents to form vesicular zone and membrane zone in sperm nucleu. The secondary spermatophore layer is distinctly subdivided into inner region and outer region. The loose outer region consists of canaliculated reticulum and large flocculent vesicles.

输精管内的精荚为管状，由精子群、精荚基质及初级精荚壁和次级精荚壁组成，初级精荚壁与精荚基质是相连续的，它们之间无明显界限，两者均由电子密度较高的纤丝状基质和絮状泡和同心圆泡组成，但后者不含精子，后者中的絮状泡和同心圆泡常在精子主体部周围释放内含物，可能与形成精子细胞核中的泡状带和膜状带有关，在交配后的雌虾，其头胸部腹面上粘着的精荚中，其基质内已不见絮状和同心圆泡，仅见稀疏的纤丝。
