激素的產生
男性與女性的性腺(睾丸與卵巢)都產生一些激素。這些性腺激素被分為雌激素 (estrogens) 和雄激素(androgens)。然而,這些術語容易使人誤解,因為發現男女體內都可以有雌激素和雄激素。只是存在導致兩性差別的這些激素的量和平衡存在差異。

The Internal Sex Organs: The Testicles

The Production of Hormones
The male and female gonads (testicles and ovaries) also produce certain hormones. These gonadal hormones have been divided into male hormones (androgens) and female hormones (estrogens). However, these terms are somewhat misleading because both"male" and "female" hormones can be found in every male and female body. It is only the quantity and balance of these hormones that differ.
