The results demonstrate that fertility rates in women with MS do not differ from the general population, and the frequency of pregnancy complications, including stillbirths, congenital malformations, and spontaneous abortions, does not exceed population-level rates. A reduction in MS activity is observed during the third trimester of pregnancy; however, the risk of relapses increases by 50% within the first three months postpartum, necessitating timely resumption of therapy. Pregnancy management in women with MS should involve interdisciplinary collaboration between neurologists and obstetricians and gynecologists, personalized therapy adjustments, and patient education about safe treatment strategies. Certain DMTs can be safely used during pregnancy and lactation, though careful benefit-risk assessment remains crucial. Women with MS can successfully plan and carry pregnancies to term without significant untoward effects on outcomes. Developing personalized management strategies for these patients will help minimize risks and improve their quality of life.</p></abstract><trans-abstract xml:lang="ru"><p>В статье представлен обзор данных литературы о влиянии рассеянного склероза (РС) на фертильность и течение беременности, об особенностях приёма препаратов, изменяющих течение РС (ПИТРС), и грудного вскармливания. Результаты демонстрируют, что у женщин с РС показатели фертильности не отличаются от общей популяции, а частота осложнений беременности, включая мертворождения, врождённые пороки и спонтанные аборты, не превышает популяционные показатели. Установлено снижение активности РС в III триместре беременности, однако в первые 3 мес после родов риск обострений возрастает на 50%, что требует своевременного возобновления терапии. Ведение беременности у женщин с РС должно включать междисциплинарное сотрудничество невролога и акушера-гинеколога, индивидуальную корректировку терапии и повышение осведомлённости пациенток о безопасных тактиках лечения. Некоторые ПИТРС могут безопасно использоваться в период беременности и лактации, при этом важно учитывать соотношение риска и пользы. Женщины с РС могут успешно планировать и вынашивать беременность без значимого влияния на её исходы. Разработка индивидуальных стратегий ведения таких пациенток позволит минимизировать риски и повысить качество их жизни.</p></trans-abstract><kwd-group xml:lang="en"><kwd>multiple sclerosis</kwd><kwd>pregnancy</kwd><kwd>fertility</kwd><kwd>breastfeeding</kwd><kwd>DMTs</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рассеянный склероз</kwd><kwd>беременность</kwd><kwd>фертильность</kwd><kwd>грудное вскармливание</kwd><kwd>препараты, изменяющие течение рассеянного склероза</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Haki M, AL-Biati HA, Al-Tameemi ZS, et al.
