LH =黃體生成素；FSH=卵泡刺激素。在女性：LH在產生雌激素和孕激素方面起重要的作用，FSH刺激卵細胞（卵泡）的發育。在男性：LH在產生睾丸激素方面起重要作用，FSH在產生精子方面起重要作用。

LH = Luteinizing Hormone; FSH = Follicle Stimulating Hormone. In females: LH plays an important role in the productions of estrogens and progesterone, FSH stimulates the development of egg cells (ova). In males: LH plays an important role in the production of testosterone, FSH plays an important role in the production of sperm.

激素的作用：插圖
“性激素”的產生有一個回饋系統：在腦下部區域（下丘腦和垂體）的兩個腺體產生激素刺激性腺（卵巢和睾丸），反過來，性腺也影響著這兩個腺體。女性和男性的各種激素的綜合作用造就了兩個性別之間的次級性徵和其他各種差別。
The Role of Hormones: Illustration
The production of “sex hormones” represents a feedback system:
Two glands in the lower brain region (hypothalamus and pituitary gland) stimulate the gonads (ovaries in females; testicles in males) which, in turn, influence their stimulators. The different mixture of hormones in females and males produces the secondary sexual characteristics as well as other differences between the sexes.
