“…Sperm have been reported in the uterus of several chondrichthyan species (Metten, 1944;Lewis, 1982;Leesa et al, 1986;Fishelson and Baranes, 1998;Hamlett, 2002;Hamlett et al, 2002); some of these report the sperm embedded in the uterine epithelium (Metten, 1944;Hamlett, 2002) and the uterine resorption of sperm (Lewis, 1982). Interaction with the uterine epithelium may assist in pre-paring sperm for fertilization through capacitation and hyperactivation or represent phagocytosis of superfluous sperm (Roland, 1969;Bedford, 1970;Hafez, 1978;Birkhead and Moller, 1998;Sever and Brizzi, 1998;Hamlett, 2002).…”

Oviducal gland morphology, the microscopic organization of the terminal zone, and sperm storage were described in the female gummy shark (Mustelus antarcticus). Mustelus antarcticus is a nonplacental viviparous hound shark, which displays minimal histotrophy during embryonic development. The animals examined represented all stages of maturity and gestation. The oviducal gland was found to have the same fundamental zonation as in most chondrichthyans. Using recent terminology, the oviducal gland of chondrichthyans has an anterior club zone, followed by a papillary zone, both of which produce jelly that surrounds the egg, a baffle zone that elaborates the tertiary egg envelope and a terminal zone, where sperm storage occurs. Each zone is composed of simple tubular glands that connect to transverse grooves, which extend the full width of the gland. The exception is the terminal zone, which does not have transverse grooves but consists of individual tubules. The microscopic organization and histochemical nature of the zones display similar patterns to those of other chondrichthyan genera. Tubules of the terminal zone contain four types of cell: ciliated cells, alcian blue-positive secretory cells, periodic acid-Schiff and alcian blue-negative secretory cells, and secretory columnar cells. These tubules end in recesses, the sperm storage tubules, which extend beyond the periphery of the baffle zone. Sperm were stored in the sperm storage tubules of all maturing and mature animals examined. Of note is the observation of stored sperm in an animal 1 year prior to first ovulation. Sperm were also observed throughout the uterine sphincter, body of the uterus, isthmus, and oviduct of maturing and mature animals, and in the uterine sphincter of an immature animal. These sperm represent immediately postcopulation aggregations of sperm and sperm in the process of migrating to the site of storage or to the site of fertilization.

Sperm ligand on Escherichia coli that agglutinates human spermatozoa has been extracted from washed E. coli cells by incubating with 3M NaCl for 12 h at 37º C under shake conditions (150 rpm). Further the sperm ligand was purified after extensive dialysis against double distilled water by step down chromatography procedures (molecular weight sieving, anion exchange). The purification procedure yielded a protein of apparent homogeneity. The ligand was heat labile as it could not withstand a temperature of 60º C for 10 minutes. The ligand did not pass through the dialysis tubing. The molecular weight was found to be ~71KDa. Electron microscopy studies of washed sperm cells treated with purified ligand showed profound morphological alterations to head, neck and tail.
