В настоящее время выбор стартовой дозы и схемы осуществляется эмпирически, что удлиняет период подбора терапии и повышает риск ее осложнений. Учет индивидуальных особенностей пациента может помочь в оптимизации терапии.</p></sec><sec><title>ЦЕЛЬ</title><p>ЦЕЛЬ. Исследовать факторы, влияющие на суточную потребность в смесях эфиров тестостерона у трансгендерных мужчин.</p></sec><sec><title>МАТЕРИАЛЫ И МЕТОДЫ</title><p>МАТЕРИАЛЫ И МЕТОДЫ. Данное исследование является наблюдательным «случай-контроль». Включались пациенты до начала тестостерон-заместительной терапии (ТЗТ). Выполнен анализ факторов, взаимосвязанных с суточной потребностью препаратов тестостерона. Из интересующих факторов рассмотрены индекс массы тела (ИМТ), результаты анализов крови на общий тестостерон и функциональное состояние печени и почек. Проведена оценка схем ТЗТ у трансгендерных мужчин. Для расчета использованы формулы ИМТ и среднесуточной дозы тестостерона. На основе полученных данных сделаны выводы, позволяющие определить необходимую схему ТЗТ у разных трансгендерных мужчин на раннем этапе гормональной коррекции.</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ. В наше исследование были включены 58 трансгендерных пациентов FtM, которым назначались препараты тестостерона с идентичным составом. Нами была установлена положительная корреляция между ИМТ и дозой тестостерона у пациентов II группы (р=0,04).</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ. В заключение приведены полученные схемы гормональной коррекции трансгендерного перехода с минимальным риском возможных осложнений. Наши результаты продемонстрировали наличие зависимости между ИМТ пациентов с избыточной массой тела и ожирением и потребностью в ТЗТ. Для пациентов с ИМТ от 25 до 29 кг/м2 интервал между инъекциями смеси эфиров тестостерона не отличается существенно от такового в группе с ИМТ ниже 25 кг/м2 и составляет в среднем 1 раз в 18 дней, а в группе с ИМТ≥30 кг/м2 изученные препараты эфиров тестостерона необходимо назначать 1 раз в 2 нед (14 дней).</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>BACKGROUND</title><p>BACKGROUND: The basis for the management of transgender patients is the use of various hormonal correction schemes necessary for changing the hormonal sex and, possibly, further preparation for surgical correction. Currently, the choice of the starting dose and the scheme is carried out empirically, which lengthens the period of selection of therapy and increases the risk of its complications. Taking into account the individual characteristics of the patient can help in optimizing therapy.</p></sec><sec><title>AIM</title><p>AIM: Investigate Factors Affecting the Daily Demand for Testosterone Ester Blends in Transgender Men</p></sec><sec><title>MATERIALS AND METHODS</title><p>MATERIALS AND METHODS: This study is a case-control observational study. Patients included prior to initiation of testosterone replacement therapy. The analysis of factors interrelated with the daily requirement of testosterone preparations was carried out. Among the factors of interest, the body mass index (BMI), the results of blood tests for total testosterone and the functional state of the liver and kidneys are considered. Testosterone replacement therapy (TRT) regimens were evaluated in transgender men. For the calculation, we used the formulas for BMI and the average daily dose of testosterone. Based on the data obtained, conclusions were drawn that allow determining the necessary TRT scheme in different trans-gender men at an early stage of hormonal correction.</p></sec><sec><title>RESULTS</title><p>RESULTS: Our study included 58 transgender FtM patients who were prescribed testosterone preparations with an identical composition. We found a positive correlation between BMI and testosterone dose in patients of group II (p = 0.04).</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION: In the conclusion, the obtained schemes of hormonal sex reassignment with a minimum risk of possible complications are presented. Our results demonstrated a relationship between BMI in overweight and obese patients and the need for TRT. For patients with a BMI of 25 to 29 kg / m2, the interval between injections of a mixture of testosterone esters does not differ significantly from that in the group with a BMI below 25 kg / m2 and averages once every 18 days, and in the group with a BMI ≥ 30 kg / m2 tested testosterone ester preparations should be prescribed once every 2 weeks (14 days).</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>гормонально-заместительная терапия</kwd><kwd>гормональная коррекция пациентов-трансгендеров</kwd><kwd>индекс массы тела</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hormone replacement therapy</kwd><kwd>hormonal correction of transgender patients</kwd><kwd>body mass index</kwd></kwd-group></article-meta></front><back><ref-list><ref id="cit1"><element-citation><name><surname>Winter</surname> <given-names>Sam</given-names> </name> <name><surname>Diamond</surname> <given-names>Milton</given-names> </name> <name><surname>Green</surname> <given-names>Jamison</given-names> </name> <name><surname>Karasic</surname> <given-names>Dan</given-names> </name> <name><surname>Reed</surname> <given-names>Terry</given-names> </name> <name><surname>Whittle</surname> <given-names>Stephen</given-names> </name> <name><surname>Wylie</surname> <given-names>Kevan</given-names> </name> <article-title>Transgender people: health at the margins of society</article-title> <source>The Lancet</source> <year>2016</year> <month>06</month> <fpage>390</fpage> <lpage>400</lpage> <volume>388</volume> <issue>10042</issue> <object-id pub-id-type="doi" specific-use="metadata">10.1016/s0140-6736(16)00683-8</object-id></element-citation></ref><ref id="cit2"><element-citation><name><surname>Heylens</surname> <given-names>Gunter</given-names> </name> <name><surname>De Cuypere</surname> <given-names>Griet</given-names> </name> <name><surname>Zucker</surname> <given-names>Kenneth J.</given-names> </name> <name><surname>Schelfaut</surname> <given-names>Cleo</given-names> </name> <name><surname>Elaut</surname> <given-names>Els</given-names> </name> <name><surname>Vanden Bossche</surname> <given-names>Heidi</given-names> </name> <name><surname>De Baere</surname> <given-names>Elfride</given-names> </name> <name><surname>T'Sjoen</surname> <given-names>Guy</given-names> </name> <article-title>Gender Identity Disorder in Twins: A Review of the Case Report Literature</article-title> <source>The Journal of Sexual Medicine</source> <year>2011</year> <month>12</month> <fpage>751</fpage> <lpage>757</lpage> <volume>9</volume> <issue>3</issue> <object-id pub-id-type="doi" specific-use="metadata">10.1111/j.1743-6109.2011.02567.x</object-id></element-citation></ref><ref id="cit3"><mixed-citation publication-type="commun" publication-format="web"><article-title>Mezhdunarodnye meditsinskie standarty pomoshchi transgendernym lyudyam</article-title> / Pod red.
