Generation of free radicals in ejaculate samples from infertile patients was evaluated using chemiluminescent technique. The presence of antisperm antibodies in samples increased the possibility of damages to spermatozoon plasma membranes due to excessive generation of free radicals.
The paper gives data on the frequency and pattern of infertile marriage by referrals to the clinic of infertility, Center of Obstetrics, Gynecology, and Perinatology, Russian Academy of Medical Sciences. Tubuloperitoneal disorders are the leading and challenging abnormality in aphoria. Endometriosis and endocrine types of infertility occupy the second place in their incidence. Emphasis is laid on the role of laparoscopy in the complex examination of infertile females. Analysis of the causes of male infertility suggests that abnormalities resultant from sexually transmitted diseases are prevalent. The diagnosis and treatment of marriage infertility caused by immunological and psychogenic factors call for further development.
OBJECTIVE: To assess the use of flow cytometry (FCM) analysis of living spermatozoa subjected to indirect immunofluorescence staining with the mouse anti-human immunoglobulin (Ig)G monoclonal antibodies (FCM test) as an objective method for the detection of antisperm antibodies in semen and serum. DESIGN: The comparative studies were conducted with the direct and indirect mixed antiglobulin reaction (MAR) and FCM test performed by FCM analyzer FACSCAN (Becton Dickinson Immunocytometry Systems, Mountain View, CA). SETTING: Clinical infertile service. PATIENTS: Seventy-six semen and 20 sera samples of infertile patients were analyzed. RESULTS: For IgG in semen there was a highly significant correlation between the direct MAR and FCM test. Six of 12 IgG-positive samples revealed also IgA, and just one sample, which showed negative MAR, was positive for IgM in FCM test. Flow cytometry test and indirect MAR showed also a highly significant correlation of the results of IgG detection in sera. CONCLUSIONS: Flow cytometry test may be used to verify that IgG antisperm antibodies are on the surface of living spermatozoa either retrieved directly from an ejaculate or after exposure to serum and to determine proportion of antisperm antibodies-positive spermatozoa, titer, and quantity of antibodies bound to the cell surface.
Detection of antisperm antibodies is an important step of the diagnosis of infertility. In present study we conducted comparative studies with the detection of antisperm antibodies in IgG, IgA and IgM classes on the surface of living spermatozoa by flow cytometry and with Mixed Agglutination Reaction and Sperm immobilization. Our data show that flow cytometry may be used to verify that immunoglobulins are on the surface of living spermatozoa, either retrieved directly from an ejaculate or following exposure to cervical mucus or serum and to determine their isotype, proportion of sperm which bound antibody and quantity of immunoglobulins bound to cell surface.
The paper presents the experience in administration of testosterone andekanoate (andriol) in males suffering from infertility due to idiopathic oligozoospermia. Andriol produced a positive effect on ejaculate. As a result, 25% of the wives got pregnant. The response to andriol arises from posttesticular effects on maturation of spermatozoa and stimulation of the accessory sexual glands.
