Parasitic infection and disturbances of fertility in humans

According to literature of the problem, the disturbances of reproductiveness of human in various parasitic infections are discussed. The mechanisms disturbing the proper functioning of the hosts's reproductive system are not sufficiently understood. They may remain in association not only with a direct or indirect effect of the parasite on the host's endocrinal glands and sexual organs, but also with the host's overall reaction to stress or toxic influences. Parasite's activity may lead to abortion or a significant decrease in fetal body weight. Embryo or fetus may be also damaged in an intrauterine infection.
