Currently, there is a downward trend in the birth rate, with the percentage of infertile couples being increased, despite the development of reproductive medicine and demographic policy. National programs are aimed at increasing the spread of family planning methods and reducing the number of child marriages. In addition to deep behavioral changes predetermined by the historical, social, economic, cultural and moral situation of an individual and society as a whole, the changes in the birth rate are based on adaptive mechanisms during sexual selection. In particular, a substantial research has focused on identifying additional biomarkers of male fertility in seminal plasma. There have been proven to exist differences in their absolute and relative levels between fertile men and men classified as infertile, based on sperm parameters of the World Health Organization. Studies dating back to the 1920s suggested a multifaceted role for seminal fluid in the reproductive process. It has been established that the paternal biological contribution to pregnancy and related ability to influence the reproductive outcome goes beyond simple provision of male gametes at conception. A new paradigm is emerging detailing an importance of communication between father and mother during gestation as it is associated with maternal tolerance to fetal antigens and, ultimately, pregnancy success.</p></abstract><trans-abstract xml:lang="ru"><p>Репродуктивное поведение является комплексной категорией и связано с системой действий и коммуникаций, предпринимаемых мужчиной и женщиной в отношении процесса зачатия, вынашивания и рождения детей, включая практики планирования, а также способы контроля. В настоящее время наблюдается тенденция снижения рождаемости, увеличивается процент бесплодных семейных пар, несмотря на развитие репродуктивной медицины и демографической политики. Государственные программы направлены на повышение распространения методик планирования семьи и сокращение количества детских браков. Кроме того, в основе изменений рождаемости, помимо глубинных поведенческих, предопределяемых историческим, социальным, экономическим и культурно-нравственным положением отдельного индивида и общества в целом, лежат адаптивные механизмы во время полового отбора. В частности, значительное количество исследований было сосредоточено на выявлении дополнительных биомаркеров мужской фертильности в семенной плазме. Доказано существование различий в их абсолютных и относительных уровнях между фертильными мужчинами и мужчинами, классифицированными как бесплодные, на основе спермопараметров Всемирной организации здравоохранения. Исследования, проведенные еще в 1920-х годах, предположили многоплановую роль семенной жидкости в репродуктивном процессе. Установлено, что биологический вклад отца в беременность и его возможность влиять на репродуктивный результат выходит за рамки простого обеспечения мужскими гаметами при зачатии. Становится очевидной новая парадигма, детализирующая важность общения между отцом и матерью во время вынашивания, поскольку она связана с материнской толерантностью к антигенам плода и, в конечном итоге, с успехом беременности.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>беременность</kwd><kwd>семенная жидкость</kwd><kwd>репродуктивный потенциал</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pregnancy</kwd><kwd>semen fluid</kwd><kwd>reproductive potential</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">Aldunate M., Srbinovski D., Hearps A.C. et al.
