[Testosterone content of the blood plasma in mature animals of various species during modeling of a pathological process in the testes using testicular antibodies].
Testosterone content in the blood plasma before and after administration of testicular antibodies (IgG and IgM) isolated from respective antisera was studied by a radioimmunoassay in 86 mature mice, rats and guinea-pigs. IgG at a dose of 0.4-2.4 mg of protein per 100 g of body mass decreased testosterone content in the blood plasma 1.6-4.2-fold early after administration (on the 3rd-6th day) in animals of all species. The level of testosterone remained below the basal values in the course of 33 days after the administration of immunoglobulins. A single administration of IgG at a dose of 2.4 mg of the protein resulted in a less damaging effect on the animals' testes than the same amount of the protein administered in fractions (at a dose of 0.8 mg three times a day). IgG produced a higher inhibiting effect than IgM administered at the same doses. Immunoglobulins of class G isolated from antisera which are specific to the testicular tissue, can be used for the simulation of a pathological process in the testes for a study of the etiology and pathogenesis of hypogonadism which is quite frequent in clinical practice.
