在7种鸟形目动物和2种雄性硬蜱中，精荚在雄性身体外连续形成三个阶段：(1)外种球，即外精囊形成；(2)充满精子；(3)内囊，即内精囊，被挤出到外精囊中。外生精囊和内生精囊的形态与其生物学功能有关。描述了在女性生殖器开口沉积精荚后，内精囊的外翻和外翻，以及精子从外精囊向内精囊的转移。
In seven species of Ornithodoros and two species of Argas ticks the spermatophore is formed outside the male body in three consecutive stages: (i) the outer bulb, the ectospermatophore, is formed; (ii) it is filled with sperm; and (iii) the inner capsules, the endo-spermatophore, are extruded into the ecto-spermatophore. The morphologies of the ecto-spermatophore and the endo-spermatophore are related to their biological functions. Eversion and evagination of the endo-spermatophore after deposition of the spermatophore on the female genital opening, as well as transfer of sperm from ecto-spermatophore to endo-spermatophore, are described.
