@ The Italian - I believe the Gibson (not to be confused with the classic cocktail of the same name) is gaining international popularity among the megarich:
Mrs Oligarch: "Viktor, do you have any small change, I need to pay the milkman"?
Mr Oligarch: "Da. There are a couple of Gibsons on the dresser. Take what you need".
As for arithmetic, the fatal flaw in PLE/RP historical estimates is that they are based on lifetime prevalence ("have you ever experienced PE") rather than point prevalence ("do you currently suffer from PE?), and assume that all men with PE represent a treatment pool, when the reality is that not all men with PE are bothered by their condition and the number actually seeking and accepting treatment is very small (indicated in all PE/sexual dysfunction studies, regardless of country).
I've used Germany as an example as there is high-quality survey data available (almost 2,500 participants), which, importantly, used a broad PE definition to capture those bothered by their PE (14.5% of those surveyed) rather than the narrow clinical definition. Of those bothered by PE, only 10% sought medical advice and of those, 70% received medical treatment. You can download the publication here:

German male population (18-64 years) is 25.3m. If we assume uniform prevalence and treatment-seeking across age groups (it's not, but we can ignore the error):
25.3m (male adults) divided by PE point prevalence (14.5%) = 3.66m men "bothered" by their PE. Ten per cent seek treatment (366, 505 men), and 70% accept treatment (256,554 men). Adherence to PE treatments (and ED treatments) is low, so the treatment pool remains more or less the same size, with new treatment seekers replacing those falling out of treatment.
Of those under treatment, around a third will also have ED or other co-morbidity. I've assumed (perhaps generously) an even split between oral and topical medication for the remainder, with Fortacin taking 50% of all topical prescriptions or 15% of the entire treatment pool:
256,554 multiplied by peak uptake (15%) = 38,483 men on Fortacin, at Euro 24 per canister (wholesale price), with an average use of 3 canisters per patient per year, = Euro 2.77m, 15% royalty gives Euro 415, 617 (approximately 0.33 Gibsons, at USD 1.5m = Euro 1.27m).
The EU5 calculation is identical, except I've averaged out national PE point prevalence (12%).
Sensitivity analysis (number of scripts per year, second-line treatment capture) doesn't change the overall conclusion that, without a massive increase in treatment seeking (1000-2000%?), revenues cannot reach the giddy levels projected by RP. Given time, sales might be more or less in line with the value reflected in the Recordati deal.
