Effects of Toxoplasma gondii Infection in Level of Serum Testosterone in Males with Chronic Toxoplasmosis

چکیده
BACKGROUND Toxoplasma gondii is an intracellular protozoan parasite that infects human and animals. Toxoplasma parasites are isolated from different parts of animals even from semen but there are little information about the effect of toxoplasmosis on fertility in animals and humans. In present study, the effect of chronic toxoplasmosis on serum levels of testosterone in men was studied. METHODS In this case-control study, 1026 men referred to Arak Post Marriage Center were selected. Three ml of blood samples were collected and sera separated by centrifugation at room temperature. These sera were analyzed for detection of anti-T. gondii IgG antibody. Next 365 positive sera were selected as cases and also the same number of negative sera (365) as controls. Finally the level of testosterone was analyzed for the cases and controls samples. RESULT Serological tests on the sera of 1,026 men in Arak City showed that 365 of them had anti-Toxoplasma antibody. Comparison of testosterone concentration in case and control groups showed that testosterone concentration in case group was less than control group and this difference was statistically significant (P<0.05). CONCLUSION The chronic toxoplasmosis could affect reproductive parameters in men.

Background and aims: Toxoplasmosis is a very common disease in the world. Two types of acquiredtoxoplasmosis have been detected. In the chronic toxoplasmosis, the abnormality of tissue functionis little but, in acute toxoplasmosis, function of RES system becomes interrupted. The assessment oftoxoplasma antibody with tissue enzymes in this stage is very important. Furthermore, ...

Background and aims: Toxoplasmosis is a parasitic disease which may cause some laboratory symptoms in infected individuals. One of the main ways of transmition this organism is placenta to fetus pathway. If this transmission occurs in the 3th month of pregnancy, the abortion, central nerve system and ocular disorder will happen. Because of this issue, the precise technique for detection of Toxo...
