The Soviets seem to have discovered it first and announced it to other national health organizations and, I am told, articles are starting to appear in the US about it. When I was over in Russia some of the people I spoke with including the Intourist host explained that sex as such in the USSR is one colossal nono and taboo. The society is quite puritan and Victorian about sex believing that it is meant only for the propagation of the species in order to populate the Motherland. All this is after a due process marriage, of course. Naturally hormones don't care abour Lenin.
Men do have hormone arousals and attacks.
In addition flats are small and scarce, with two or even three families living in a four-room apartment. Now, on top of all this, in Russia you must earn the privilege to have a household pet. So we see Igor getting all hot and horny with his family all around his ears. Igor fetches a large bath towel 'because the draft thru the wall cracks bother him' and in a flash the little cuddly dog is popped under it. Some minor commotion ensues and the dog jumps out all terribly confused.
