Cryopreservation of Rat Sperm
The laboratory rat, Rattus norvegicus, was the first mammalian species domesticated for scientific research, which work dating back to before 1850. From this auspicious beginning, the rat has become the most widely studied experimental animal model for biomedical research (Jacob, 1999). Since the development of the first inbred rat strain by King 1909, over 500 inbred rat strains have been deve...
متن کاملCytoskeletal proteins F-actin and β-dystrobrevin are altered by the cryopreservation process in bull sperm.
The cryopreservation process has an important impact on sperm structure and physiology. The negative effects have been mainly observed on the plasma membrane, which is directly stabilized by the cytoskeleton. Since cytoskeleton proteins are osmosensitive and thermosensitive, the aim of this study was to evaluate the damage caused to the bull sperm cytoskeleton by cryopreservation (freezing-thaw...
متن کاملComputer assisted semen analysis for quantification of motion characteristics of bull sperm during cryopreservation cycle
Aim: The study was undertaken to quantify and to analyze the changes in the motion characteristics of bull spermatozoa during various stages of cryopreservation cycle. Materials and Methods: Using computer assisted semen analysis (CASA) technique, 26 ejaculates, collected from two Jersey bulls were analyzed for motility, head behaviour and swimming pattern of spermatozoa on dilution, pre-freeze...
متن کاملCryopreservation alters the levels of the bull sperm surface protein P25b.
Fertility of frozen-thawed bull sperm is reduced by cryopreservation. Freezing-thawing procedures can result in as much as a sevenfold fertility decrease. Sperm mortality and loss of motility do not fully explain the reduced fertility of cryopreserved semen; they may be partially explained by the loss of sperm surface proteins, which are necessary for fertilization. We have previously identifie...
متن کاملHuman Sperm Cryopreservation
As the demand for assisted reproductive techniques in humans increases, so does the demand for the oocytes and sperm that are essential for these techniques. Human sperm banks play a key role in assisted human reproduction, as a reservoir of sperm from the semen of donors and as an option for genetic preservation for some patients. There are different techniques that can be used to store human ...
