Early on in male development, testosterone helps the external sex organs to differentiate into male genitals and causes the testes to descend from the abdomen into the scrotal sac.

在男性发育的早期，睾酮帮助外部性器官分化成男性生殖器，还可促进睾丸从腹腔降入阴囊。

Being that we, as males, don't often compare our scrotal dynamics with other men, most people aren't aware of their deformity, at least not at first.

由于我们作为男性，并不经常与其他男性比谁的蛋蛋更晃动，因此大多数人并有意识到自己的畸形，至少一开有。

The theory of occupational cancer was later confirmed in 1775 by British surgeon Percival Pott, who found that exposure to soot was causing scrotal cancer among chimney sweeps.

职业癌症理论后来在1775年被英国外科医生珀西瓦尔·波特证实，他发现接触烟尘导致了烟囱清扫工的阴囊癌。

And, I mean, you've seen guys with blood work, right, and they've managed to get their testosterone up quite dramatically, right, like through scrotal application?

我的意思是， 你见过那些通过血液检测的男性吧，他们成功大幅提升了睾酮水平， 错吧，就像通过阴囊涂抹那样？
