...because priapism. 
TYY
Most of the ads on the nightly news seem to be geared more toward older middle age and beyond, the types who would most likely be watching that particular program at that time. 
Also, I watch a lot of the "nostalgic" TV channels and almost all of their ads are obviously geared toward senior citizens, who watched these old shows back in the day.
ON EDIT: Had to laugh just now... right when I sent this post there was a pop-up for explosive diarrhea at the top of the screen...timing is everything.
you'd know the answer...
These ads would be much more explicit 
Nothing against Asia by saying this, I'm 1/2 Chinese, and in fact this is about our western hangups. Many Asian cultures don't have nearly the kind of hangups we do here in the west about bodily functions. Think about it we can't depict blood, urine or feces in ads about products that are all about these bodily functions. Blood and urine has to be blue or some other replacement colour / fluid. And forget depicting feces, we have to tip toe around that one by beating all around the bush. In Asia, it varies from country to country but I'm thinking mainly China, they don't have as strong a hangup about these issues as we do. You WILL see similar ads for feminine hygiene products, toilets, and the like. But chances are they will be more in your face and show or talk more about the unmentionables than we do here. In a Chinese mall here, here I mean Vancouver, there is a store that sells those electronic Japanese bidet toilets. There is a salesman there who talks to the local Chinese customers walking buy. Trust me for the most part he will be much more candid about these kinds of topics than we would in the west.
