The content of immunoglobulins in the cervical mucus has been determined quantitatively by the method of radial immunodiffusion. IgG and IgA has been ascertained in all samples, whereas IgM was not measurable. The concentrations of IgG and IgA in the cervical mucus was compared with those of mucous--membrane and of blood-serum. It was discussed the importance of periodical changes of cervical mucus for the penetration of spermatozoa.

The content of total protein and immunglobulins in the parotid saliva and blood serum of pregnant women and healthy test persons has been determined by the biuret method and radial immunofiffusion. It was stated that total protein and IgG in the parotid saliva were higher in pregnant women than in healthy test persons, whereas the IgA-levels don't show any differences. IgM was not measurable in the parotid saliva. There was no relationship between saliva and serum immunglobulins. During the pregnancy show the parotid glands another typ of reaction than nonpregnant women.
Male infertility is a far more prevalent problem than is perhaps generally realized. The evaluation of testicular biopsies allows various clinical syndromes of hypogonadism to be identified and a rational basis for therapy to be established. The morphological-anatomical classification of male infertility paralleling the clinical-biochemical classification divides the different varieties of male infertility into three categories: those due to pretesticular, testicular, and posttesticular causes. Testicular biopsy is an important method in the diagnosis and management of male infertility. The procedure is simple and safe in competent hands and yields information obtainable in no other way. The increasing use of this procedure permitts a rational classification of the testicular lesions responsible for infertility and provides an intelligent basis for the institution of corrective measures or the withholding of therapy in cases in which the biopsy indicates a hopeless prognosis for fertility.
The content of total protein and immunoglobulins in the breast-milk has been determined by the biuret-method and radial immunodiffusion. The immunoglobulins IgG, IgA and IgM has been ascertained in all samples. The concentrations of total protein and of immunoglobulins are higher in the colostrum but in the breast-milk.
The immunglobulins IgA, IgG and IgM in the extracts of homogenised cervical tissue from pregnant women were measured with the help of radial immunodiffusion of Mancini et al. The values of IgA and IgG increased during investigation. The low concentrations of IgM could not be evaluated quantitatively.
At a patient with herpes gestationis the immunoglobulins IgG, IgA and IgM as well as the proteins albumin, transferrin and coeruloplasmin were determined in the serum. The relation of this illness of pregnancy with immunological factors is in discussion.
The content of total protein and immunoglobulin in the saliva of pregnant women has been determined quantitativly by the biuret-method and radial immunodiffusion. IgA has been ascertained in all samples of saliva, whereas was appears IgG in 78,55% and IgM only 52,50% of the samples. It was discussed the importance of salive-IgA during the pregnancy.
IgG, IgA and IgM in the extracts of homogenised cervical tissue were measured with the help of radial immunodiffusion of Mancini et al. IgG IgA were found to vary crith periods. On account of low concentration IgM could not be evaluated.
