“…Previous studies have localized this enzyme in the proacrosomal vesicles (Anderson, 1968;Souza et al, 1988;Thorne-Tjomsland et al, 1988;Bao et al, 1989) and the axoneme Bigliardi et al, 1970;Baccetti et al, 1971;Beaulaton andPerrin-Waldemar, 1973, Bao andDolder, 1990;Bao, 1991). ATPases have been found as integral components of the membrane in the head region of the sperm (Gordon, 1973), and in the axoneme (Anderson and Personne, 1970;Baccetti et al, 1973a, b;Yasuzumi et al, 1973;Cibert, 1985;Curtis et al, 1989). Thiamine pyrophosphatase activity has been detected in the plasma membranes of insect (Baccetti, 1977) and mollusc sperm cells.…”

Ultrastructural cytochemical techniques were used for the localization of phosphatases in spermatid and spermatozoon of the mosquito, Culex quinquefasciatus (Diptera : Culicidae). Acid phosphatase was found mainly in the trans-most portion of the Golgi complex. Thiamine pyrophosphotase was preferentially located in the cis-most portion of the Golgi complex. Glucose-6-phosphatase was located in the endoplasmic reticulum and cisternae of the transition zone between the endoplasmic reticulum and the Golgi complex. The complex membrane of the anterior acrosomal region and the axoneme showed acid phosphatase activity. Reaction products indicating the presence of acid phosphatase, thiamine pyrophosphatase, and glucose-6-phosphatase, were observed on the spermatozoon surface at the head and tail regions. These observations support the idea that various phosphatases may play some role in spermatid differentiation.

“…On the other hand, during spermiogenesis in the reptilian it has been noticed that a peculiar body appears in the cytoplasm of early spermatids, which was referred to as the tubular body in the Japanese freshwater turtle (Yasuda et al, 1966 ;Yasuzumi and Yasuda 1968) and as the membranous body in the lizard (Clark, 1967). It seems of sufficient importance to confirm the occurrence of such a body in the domestic fowl spermatid, because both domestic fowl and reptilian spermatozoa are similar in morphological features according to Schmaltz (1911) and Yasuzumi et al (1974).…”

According to Schmaltz's review (1911) on light microscopic features of several animal spermatozoa, there are completely different two types in avain spermatozoa : one of them belongs to the songbird spermatozoon which is similar to the amphibian in a long coiled eyeleteer-shaped head and in a flagellum provided with a helically coiled sheath ; and the other to the domestic fowl which is very similar to the reptilian in a short rod-shaped head and in a delicate flagellum.Recently, this fact has been confirmed with scanning electron microscopy by Yasuzumi and his coworkers (1974). With the advent of the electron microscope, many excellent studies have been performed on several avian spermatozoa and their spermiogenesis.These studies were concerned with the Galliformes (

Mature spermatozoa from the hermaphroditic duct of adult snails were examined using various techniques of light microscopy as well as scanning and transmission electron microscopy. The sperm are approximately 557 μm in length including a dextrally spiral head approximately 13 μm long. The head consists of an electron-dense nucleus sculptured into a double-ridged spiral and an acrosome projecting approximately 0.45 μm beyond the apex of the nucleus. The acrosome consists of a membrane-bound vesicle approximately 0.1 μm in diameter and a column of homogeneous material which extends along one side of the terminal spiral of the nucleus. This material is separated from the nucleus by the nuclear envelope. The neck region, though similar to that found in other pulmonates, possesses a unique coiled structure surrounding the central doublet of the axoneme. The midpiece axoneme possesses a 9+9+2 configuration anteriorly grading into a 9+2 pattern for the majority of its length. There are three mitochondrial helices - one primary and two secondary - in the midpiece. Only the primary helix persists throughout the midpiece.
