This is mainly due to socioeconomic causes as well as the increased use of contraceptives. Problems due to advanced maternal age arise also with egg donations. Only chromosome aberrations are related to the age of the donor. Paternal age also appears to play a significant role in the outcome of the pregnancy. However, opinions vary in the literature available. Counseling the couples should be addressed.</p></abstract><trans-abstract xml:lang="ru"><p>Среди женщин, отложивших беременность до более старшего возраста, наблюдается более высокая частота бесплодия, хромосомных аберраций, неудач экстракорпорального оплодотворения, внематочной беременности, самопроизвольных абортов, преэклампсии, предлежания плаценты, гестационного сахарного диабета, операций кесарева сечения, хронических заболеваний с более высокой частотой госпитализации в отделения интенсивной терапии и более высокой частотой материнской смертности. В основном это связано с социально-экономическими причинами, а также с ростом использования противозачаточных средств. Проблемы из-за преклонного возраста матери возникают и с донорством яйцеклеток: с возрастом донора связаны хромосомные аберрации. Возраст отца также играет важную роль в исходе беременности. Впрочем, имеющиеся в доступной литературе мнения различаются. Следует рекомендовать консультирование семейных пар.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>беременность</kwd><kwd>пожилой возраст матери</kwd><kwd>пожилой возраст отца</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pregnancy</kwd><kwd>advanced maternal age</kwd><kwd>advanced paternal age</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">Statistik Austria, 2015.
