One of these threatened species is the Wyoming toad (Bufo baxteri) with the last census revealing less than a hundred animals located in the wild [2].Cited by:

In the sperm of the toad Bufo marinus, an accessory fiber is displaced from the axoneme, being connected to it by the thin undulating membrane in such a way that the movement of axoneme and accessory fiber can be viewed independently.

The average sperm concentration was estimated of × /ml. Bufo amount, survival rate and motility were also measured. The current study was undertaken to examine the applicability of amphibian spermatozoa storage protocols developed with the cane toad (Bufo marinus) to a wider range of amphibian species, with a view to ultimately using these protocols for endangered species.

In Australia, at least 29 species of recently extinct or endangered frogs are from the. The male reproductive cycle of the toad, Bufo melanostictus, was studied with emphasis on spermatogenic activity, plasma androgen, and changes in the weights of testes, liver, and fat bodies.A total of 98 toads were collected between March and March in central Taiwan.

Histological evidence indicated that the spermatogenic cycle of this toad is of a fluctuating continuous by: The effect of monosaccharides (glucose, fructose) and disaccharides (maltose, sucrose, trehalose) as diluents, in cryoprotective additives containing 15% (v/v) DMSO or glycerol as cryoprotectants.

AbstractInvasive cane toads are colonizing southeastern Australia via a narrow coastal strip sandwiched between unsuitable areas (Pacific Ocean to the east, mountains to the west).

Past studies investigating the influence of abiotic factors on sperm performance during short term storage have shown that the temperature and osmolality of the storage solution can greatly affect. Temperature. Temperature is a key factor for the maturation of spermatozoa, and one of main reasons why in most mammals the testes are outside the body cavity (at least during the reproductive season).

A temperature of 37°C may be fatal for proper maturation and lead to infertility or even cause pathologies.MAININI has described (Semana Medica, 64,March ) a pregnancy test in which, following injection of pregnancy urine into the male toad (Bufo arenarum Hensel), liberation of spermatozoa.

On the other hand, refrigeration has been shown to be effective for maintaining motility over several days in cane toad (Bufo marinus) sperm collected from testes macerates (Browne et al., ) and from hormonally-induced spermatozoa of the dusky gopher frog (Rana sevosa), Fowler's toad (Bufo fowleri), Wyoming toad (Bufo baxteri), boreal toad.
