覚え方のコツ Memory Tip
andro-「男性」と -gen「生じさせるもの」の構成から、男性的特徴の発達に作用するホルモン群と覚える。testosterone is an androgen のように、androgen は総称、testosterone はその一種。androgen levels、androgen production、androgen affects hair growth が典型的な組み合わせ。
Break androgen into andro-, relating to men or males, and -gen, suggesting production or generation. This helps recall that an androgen is a hormone involved in developing or maintaining male sexual characteristics. Keep the category relationship clear: testosterone is an androgen, but androgen does not mean only testosterone. Medical and biological texts commonly mention androgen levels, androgen production, and androgen effects on features such as hair growth. Also remember that people of all sexes produce androgens; the term describes the hormone’s biological activity, not the sex of the person who has it.

androgen の語源・成り立ち Etymology
ギリシャ語anēr/andros（男・男性）+ -gen（生じさせるもの）の構成で、「男性を作り出す物質」が原義。android（人造人間）やgenerate（生成する）と同根。男性的特徴の発達を促すホルモンの総称として命名された。
Androgen was formed from Greek anēr, with the stem andr-, meaning “man” or “male,” and the element -gen, from Greek roots associated with producing or generating. The name was created for substances that promote the development of male characteristics. The first element also appears in android, while the second is found in many scientific terms concerning production or origin. In modern endocrinology, androgen names a class of hormones rather than one single substance.
