[Toxocariasis: spread and impact on reproductive health].

To study the prevalence of toxocariasis and its impact on the reproductive health of inhabitants in the Saratov Region, enzyme immunoassay was used to examine 1404 patients, including 210 children, 912 females, and 282 males. Toxocariasis was shown to be a risk factor of male (oligoasthenozoospermia) and female (tuboperitoneal) infertility. The high incidence of toxocariasis in females with reproductive dysfunction (recurrent abortion) and an aggravated obstetric history complicated by chronic renal diseases is indicative of the existence of the urogenital form of toxocariasis. Toxocariasis greatly increases a risk of giving birth to a baby with clinical manifestations of intrauterine infection (IUI), promotes homeostatic disorder and the formation of long-term pathology in babies with IUI. At the same time, there was a significant relationship of abnormal cardiotocograms to toxocariasis and to the presence of Trichomonas, Mycoplasma, Chlamydia, and Cytomegalovirus.
