使用来自野生种群和实验室中暴露于三丁基锡 (TBT) 的雌性的标本，对表现出雌性的雌性岩壳 Thais clavigera 的雄性生殖器（阴茎和输精管）的发育特征进行了组织学检查。在野生雌性T. clavigera 中观察到多种输精管形态发生模式，并总结其特征。然而，在TBT暴露雌性中，仅在阴茎下方或后方观察到初始阶段未成熟的输精管，在靠近囊腺的阴道口（即外阴）处未观察到输精管，这与野生雌性中观察到的输精管形成特征不同。考虑到野生雌性标本和实验室中暴露于 TBT 的雌性标本的观察结果，T. clavigera 的输精管序列 (VDS) 指数被建议为 VDS 1-6。
The characteristics of the development of male genitalia (penis and vas deferens) in imposex-exhibiting female rock shells, Thais clavigera, were histologically examined using specimens from a wild population and tributyltin (TBT)-exposed females in the laboratory. A variety of vas deferens morphogenesis patterns were observed in wild female T. clavigera, and the characteristics were summarized. The immature vas deferens at an initial stage, however, was only observed beneath or behind the penis, and no vas deferens was observed close to the vaginal opening (i.e., vulva) of the capsule gland in TBT-exposed females, which was different from the characteristics of vas deferens formation observed in wild females. Taking into consideration both the observed results from wild female specimens and from TBT-exposed females in the laboratory, the vas deferens sequence (VDS) index for T. clavigera was proposed as VDS 1-6.
