Сегодня беременностей близнецами больше, чем когда-либо прежде – исследование

LIFE

Количество близнецов на каждую тысячу беременностей с 1980 года по сей день увеличилось примерно на треть. Об этом рассказывается в новом исследовании, опубликованном в журнале Human Reproduction.

Как рассказывает Medportal.ru, сейчас рождается существенно больше близнецов, чем раньше. В 1980-х беременностей двойней было 9 на 1000, в 2015 году – 12 на 1000. То есть, можно говорить об увеличении частоты их появления за этот период на треть.

«Частота [близнецовых беременностей] сейчас максимальная за 50 лет. По всей видимости, самая высокая за всю историю», - сказал New Scientist Кристиан Монден из Оксфордского университета, соавтор исследования.

По его словам, в последние годы близнецы стали выживать гораздо чаще, благодаря достижениями медицины.

Описанное увеличение произошло преимущественно за счет появления большего количества неидентичных близнецов, которые получаются при оплодотворении различных яйцеклеток. При этом количество беременностей идентичными близнецами почти не изменилось.

По мнению специалистов, количество беременностей близнецами растет, во-первых, благодаря применению вспомогательных репродуктивных технологий, а во-вторых, считается, что в странах с высоким и средним уровнем доходов женщины стали чаще рожать детей позже, а с возрастом вероятность выхода двух яйцеклеток из яичника во время овуляции увеличивается.
