When Alexandra had not produced a male heir for Nicholas II, she was placed under a great deal of pressure.
It was about this time, a rumor, and let me stress that it was a rumor since proof has not surfaced up to this time, that Alexandra was asked to take a "lover" who had proven his ability to have male children.
Such an idea would not have shocked anyone in the Romanov circle. It would not have been the first time this kind of problem was solved by and "outsider". The best known person to have solved this problem was Catherine II " the Great".
Knowing Alexandra's love for Nicholas II, as well as her pride, such a suggestion would have caused her terrible distress. Especially if it came from her mother-in-law or one of her friends. And, we do know that she had a "false pregnancy" around this time period but we can only assume this was caused through stress of wanting to provide her husband an heir.
I've read only one name for this "royal duty" which, I assume, has managed to surface through various "rumors". His name was Orlov. Only his last name has been mention and never his christian name. Through research, there were several Orlovs who were within the "inner group" who could have been possibly suggested for such a "royal duty".
As far as I know, no one has proof that Alexandra ever had a "lover" or "lovers" during her marriage.
We do know, Nicholas II was the father of his son and heir, Alexei, according to the DNA tests on the royal remains.
