Влияние полиморфных вариантов гена андрогенового рецептора (AR) на сперматогенез и показатели семенной жидкости у мужчин с различным генотипом по другим локусам недостаточно изучено.</p><p>Цель работы - исследование влияния (CAG)-полиморфизма гена AR на сперматологические параметры у мужчин с нарушением фертильности с наличием и отсутствием частичных делеций региона Д2Рс Y-хромосомы. Материалы и методы. В исследование были включены 988 неродственных российских пациентов с патозооспермией, из них 591 пациент без микроделеций Y-хромосомы и 397 пациентов с частичными делециями региона AZFc Y-хромосомы. Контрольную группу составил 131 мужчина с нормозооспермией. Всем мужчинам, участвовавшим в исследовании, был выполнен спермиологический анализ и проведено генетическое исследование. Геномную ДНК выделяли из лимфоцитов периферической венозной крови и эякулята. Анализ полиморфизма (вДв)п-повтора в экзоне 1 гена AR выполняли с помощью полимеразной цепной реакции методом полиморфизма длин амплифицированных фрагментов.</p></sec><sec><title>Результаты</title><p>Результаты. Сформированы 3 группы: пациенты с патозооспермией с наличием (n = 32) и отсутствием (n = 451) микроделеций Y-хромосомы и мужчины с нормозооспермией (контроль, n = 131). Медиана и квартили количества CAG-повторов в группах составили 22 и 20-25 соответственно. По числу тринуклеотидных повторов гена AR все пациенты были разделены на подгруппы: носители коротких ((CAG)n ≤18), средних ((CAG)n = 19-25) и длинных ((CAG)n ≥26) аллелей. Средние аллели преобладали во всех группах, у мужчин без AZFc-делеций и с микроделециями их частота составила 79,3 и 81,4 % соответственно, в контрольной группе - 81,7 %.</p></sec><sec><title>Заключение</title><p>Заключение. Не выявлено корреляции сперматологических показателей (концентрации и общего количества сперматозоидов, количества живых, прогрессивно подвижных и морфологически нормальных сперматозоидов) с числом тринуклеотидных повторов. Обнаружены статистически значимые различия (р ≤0,045) по концентрации и общему количеству, количеству живых, прогрессивно подвижных и морфологически нормальных сперматозоидов между мужчинами с нормозооспермией (контроль) и пациентами с патозооспермией с наличием и отсутствием микроделеций Y-хромосомы в подгруппах носителей коротких, средних и длинных аллелей.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. The effect of polymorphic variants of the androgen receptor gene (AR) on spermatogenesis and semen parameters in men with different genotypes for other loci has not been sufficiently studied.</p><p>The aim of this work was to study the effect of the (CAG)n polymorphism of the AR gene on semen parameters in men with impaired fertility, with and without partial deletions of the AZFс region from the Y chromosome.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study included 988 unrelated Russian patients with pathozoospermia, including 591 patients without Y chromosome microdeletions and 397 patients with partial deletions of the AZFc region of the Y chromosome. The control group consisted of 131 normozoospermic men. All men who participated in the study underwent semen analysis and genetic testing. Genomic DNA was isolated from peripheral venous blood lymphocytes and ejaculate. The analysis of the polymorphism of (GAG)n repeat in exon 1 of the AR gene was performed using a polymerase chain reaction by the amplified fragment length polymorphism method.</p></sec><sec><title>Results</title><p>Results. Three groups were studied: patients with pathozoospermia with (n = 32) and without (n = 541) Y chromosome microdeletions, and normozoospermic men (control, n = 131). The median and quartiles of the number of CAG repeats in the groups were 22 and 20-25, respectively. According to the number of trinucleotide repeats of the AR gene, all patients were divided into subgroups: carriers of short ((GAG)n ≤18), medium ((GAG)n = 19-25) and long ((GAG)n  ≥26) alleles. Medium alleles prevailed in all groups; in men without AZFc deletions and with microdeletions, their frequency was 79.3 and 81.4 %, respectively, in controls - 81.7 %.</p></sec><sec><title>Conclusion</title><p>Conclusion. No correlation was found in examined cohort for semen parameters (sperm concentration and total number, number of live, progressively motile and morphologically normal spermatozoa) from the number of trinucleotide repeats. However, a statistically significant difference (p ≤0.045; FDR correction) was found in concentration and total number, number of live, progressively motile and morphologically normal spermatozoa when comparing men with nomrozoospermia (control) with patients with pathozoospermia with and without partial AZFc deletions in subgroups of carriers of short, medium and long alleles.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>андрогеновый рецептор</kwd><kwd>мужское бесплодие</kwd><kwd>патозооспермия</kwd><kwd>сперматогенез</kwd><kwd>тринуклео-тидные повторы</kwd><kwd>фертильность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>androgen receptor</kwd><kwd>male infertility</kwd><kwd>pathozoospermia</kwd><kwd>spermatogenesis</kwd><kwd>trinucleotide repeats</kwd><kwd>male fertility</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Министерства образования и науки России для ФГБНУ «Медикогенетический научный центр им. акад.
