Do you think this could be be because 阴 suggests "hidden"?  Or somehow covered over?

那么为什么男性的那个位置被称为下阴呢？下阳不会更合适吗？Then why is that place called 下阴, even though it's a place in the male body? Wouldn't 下阳 be more appropriate? :)

@ColinMcLarty I believe it's "dark" so "covered/shaded" is close. 阴，暗也。——《说文》

<p>The answer by Chinese boy is right, 陰 is a technical term for the genitals, male or female. </p>

The penis is translated as "阴茎" (literally "yin stem"), but it is a male organ. In the [traditional concepts of yin and yang](https://en.wikipedia.org/wiki/Yin_and_yang#Meanings), "阴" is generally associated with the female sex.

To support the idea, the term ["阳具"](https://zh.wikipedia.org/zh-hans/%E9%99%BD%E5%85%B7) (literally "yang tool") is also used to describe the penis (and scrotum).

Why is the penis, a male reproductive organ, associated with the word "阴"?

According [to this fengshui expert](http://fengshuichina.blog.sohu.com/93463692.html), the penis and the vagina are both named not because of the gender of the bearer, but via Western medical terminology because they originate from the perineum [(会阴)](https://zh.wikipedia.org/wiki/%E6%9C%83%E9%99%B0).

或者说在传统的观念里，头为阳，越往下即为阴。凑字数凑字数，凑字数。

阴是医学叫法，指的是平时遮住的地方。阳是传统叫法。

因为生殖器官所在的位置叫下阴，生殖器官中的“阴”和男女的“阴阳”是不能作对比的。
