The pituitary gland releases follicle-stimulating hormones, or FSH, into the blood. The normal amount of FSH in the blood depends on a person's age and gender. A normal FSH level in a pre-pubescent male ranges from 0 to 5 milli-international units per milliliter, according to Medline Plus. The normal range increases to 0.3 to 10 milli-international units per milliliter in males going through puberty. In adult males, normal FSH levels range from 1.5 to 12.4 milli-international units per milliliter.

In females, the normal range of FSH is 0 to 4 milli-international units per milliliter before puberty and 0.3 to 10.0 milli-international units per milliliter during puberty. The amount of FSH found in the blood of an adult woman depends on whether she is still menstruating or has gone through menopause. The normal range for menstruating women is 4.7 to 21.5 milli-international units per milliliter, while the normal range for post-menopausal women is 25.8 to 134.8 milli-international units per milliliter, states MedlinePlus.

Luteinizing hormone, abbreviated LH, is also released by the pituitary gland. The normal range for adult males is 1.8 to 8.6 international units per liter, reports MedlinePlus. The amount of LH in a female's blood depends on her menstrual status. Before menopause, the normal range is 5 to 25 international units per liter. It increases to 14.2 to 52.3 international units per liter after menopause.
