Диагностика мужского бесплодия актуальна. Современные авторы считают, что на долю мужского бесплодия приходится до 40–50 % всех случаев. Наиболее тяжелым считается идиопатическое мужское бесплодие, распространенность которого в Европе достигает 31–44 %.</p><p>Цель исследования – выявить морфологические изменения в ткани яичка у мужчин с необструктивной формой бесплодия.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Были обследованы 26 больных с идиопатической необструктивной азооспермией (по данным спермограммы). Группу сравнения составили 22 практически здоровых мужчины. Пациентам по показаниям выполняли биопсию яичка с последующим морфологическим анализом. Срезы ткани яичка подвергали окрашиванию гематоксилином и эозином. С помощью метода непрямого иммуногистохимического анализа выявляли универсальные факторы роста: инсулиноподобный фактор роста 1 (insulin-like growth factor 1, IGF-1), васкулярно-эндотелиальный фактор роста (vascular endothelial growth factor, VEGF), эпидермальный фактор роста (epidermal growth factor, EGF).</p></sec><sec><title>Результаты</title><p>Результаты. По данным ультразвукового исследования мошонки в В-режиме выявлены достоверные различия структуры яичка: наличие эхопозитивных включений, неоднородность паренхимы, повышение ее эхогенности (p &lt; 0,05). При окрашивании срезов яичка гематоксилином и эозином зафиксировали достоверные изменения в извитых семенных канальцах у пациентов с азооспермией: диаметр уменьшен в 1,5–2,0 раза (гипоплазия), базальная мембрана с выраженным волокнистым компонентом (фиброзирование) (p &lt; 0,05). Уровень экспрессии IGF-1 в половых клетках – до 5 %. У пациентов основной группы экспрессию маркера EGF в половых клетках, в клетках Сертоли и Лейдига, а также в миоидных клетках не обнаружили («–»). Уровень экспрессии VEGF в половых клетках – до 10 %.</p></sec><sec><title>Выводы</title><p>Выводы. Для определения репродуктивного потенциала яичек у пациентов с идиопатической необструктивной азооспермией показано использовать биопсию яичка с оценкой морфологии клеток сперматогенеза и универсальных факторов роста для выявления нарушений в регуляции сперматогенеза.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Diagnosis of male infertility is relevant. Contemporary authors, believe that the share of male infertility accounts for up to 40–50 %.</p></sec><sec><title>Objective</title><p>Objective: to improve the results of diagnostics of male infertility.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. We studied 26 men with non-obstructive azoospermia. The comparison group consisted of healthy men 22. Patients according to indications performed testicle biopsy with subsequent morphological analysis of biopsy specimens. Sections of testicular tissue was subjected to staining with hematoxylin and eosin, indirect immunohistochemical study of universal growth factors: insulin-like growth factor-1 (IGF-1), vascular endothelial growth factor (VEGF), epithermal growth factor (EGF).</p></sec><sec><title>Results</title><p>Results. According to ultrasound of the scrotum in the b-mode we also noted a significant difference in the structure of the testis: the presence of echo-positive inclusions, inhomogeneity of the parenchyma, increase of its echogenicity (p &lt; 0.05). The staining of sections of testis stained with hematoxylin and eosin, we recorded significant changes in convoluted seminiferous tubules in patients with azoospermia: the diameter is reduced in 1,5–2,0 times (hypoplasia), basal membrane with distinct fibrous component (the fibrosis) (p &lt; 0.05). The level of expression of IGF-1 in the germ cells – up to 5 %. In patients of the main group, the expression of marker EGF in germ cells, Sertoli cells and Leydig, and in modnyh cells we did not find (“–”). The level of VEGF expression in germ cells up to 10 %.</p></sec><sec><title>Conclusions</title><p>Conclusions. Severe forms of male infertility (non-obstructive idiopathic azoospermia) requires a comprehensive clinical and morphological examination.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>необструктивное идиопатическое мужское бесплодие</kwd><kwd>морфология яичка</kwd><kwd>иммунногистохимическое исследование факторов роста</kwd></kwd-group><kwd-group xml:lang="en"><kwd>non-obstructive idiopathic male infertility</kwd><kwd>morphology of testis</kwd><kwd>immunohistochemically the study of growth factors</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Гамидов С.И., Попова А.Ю., Овчинников Р.И.
