Fig 3. Steroid distributions of C18, C19, and C21 in the testis, prostate, and liver.

C18 steroids (A-C) consist of estrogen derivatives, C19 steroids (D-F) consist of androgen derivatives, and C21 steroids (G-I) consist of progestogens, gluco/mineralocorticoids, and derivatives. Each tissue had a distinct profile. C refers to vehicle-treated littermates and L to letrozole-treated littermates. The number following C or L refers to the age of the animal at tissue recovery. Data based on nmol/g tissue.
