10-15. HORMONES OF THE SUPRARENAL CORTEX
Each suprarenal cortex produces a variety of hormones which can be grouped
into three categories:
a. Mineralocorticoids (for example, aldosterone), which are concerned with
the electrolytes of the body.
b. Glucocorticoids (for example, cortisol), which are concerned with many
metabolic functions and are anti-inflammatory in nature.
c. Sex hormones. Adrenal androgens and estrogens.
Section VII. THE GONADS
In humans, the primary sex organs are known as gonads (lesson 8). The
gonads produce sex cells (gametes) and sex hormones. These sex hormones are in
addition to those produced by the suprarenal cortex (see para 10-15c).
10-17. FEMALE SEX HORMONES
In the female, the ovaries produce two types of sex hormones during the men-
strual cycle. During the first half of the cycle (days 1 - 14), the estrogens are produced.
During the last half of the cycle (days 15 - 28), progesterone is produced. These hor-
mones are concerned with female sexuality and with the preparation of female sex
organs for reproduction.
10-18. MALE SEX HORMONES
In the male, certain cells of the testes produce the male sex hormones known as
androgens (for example, testosterone). Androgens are concerned with male sexuality.
