The first sex of Russians, which on average occurs at 16 years, “ideally” should end with pregnancy -Corresponding Member of the Russian Academy of Sciences, Professor Igor Kogan
According to the Russian scientist, when a woman begins to live sex life, one must immediately begin to think about childbirth, and not after 30 years.
And therefore, today, according to the professor, one of the main tasks in Russia is reduction of the time between the first sex “at 16 years old” and genera “at 30-35 years old”.
