摘　　要：塔形马蹄螺为雌雄异体,其雄性生殖系统主要由精巢和输精管组成,没有交接器,也没有其他的附属腺体.精巢由许多精小管组成;生精小管内有处于不同发育时期的精原细胞,初级精母细胞,次级精母细胞,精子细胞和精子;输精管壁的上皮细胞游离面具有纤毛;精巢的发育具有季节性.Trochus pyramis Born is of gonophores. The male reproductive system is mainly composed of the spermaries and spermaductus, instead of mating and others glands. Spermaries comprise many seminiferous tubules. The spermatogonia in the seminiferous tubules of testis are on four different stages, including primary spermatocytes, secondary spermatocytes, spermatoon, and spermatozoa. The epithelial cells of the spermaduct wall have cilia on the dissociative side. The spermary develops seasonally.
