Hypopituitarism

Insufficient Follicle Stimulating Hormone Production

Tests

FSH Test (blood test) -test results depend on age and sexual development

Normal Values for FSH Women past menopause: 14-52 IU/L Men: 1-8 IU/L Children before puberty: 0.5-4 IU/L

Symptoms

Male, Impotence, Shriveling of testes, Decreased sperm production, Infertility

Female, No ovulation

Both, Starvation or being underweight

Variables (Factors that may influence the accuracy of the FSH test)

Age

Smoking Cigarettes

The use of hormones such as:, Testesterone, Estrogen/Progesterone (including birth control pills)

The use of medicines such as:, Cimetidine, Clomiphene, Digitalis, Levodopa

A test such as a thyroid scan or bone scan that uses a radioactive substance within a week of the FSH test

Possible causes

Pituitary gland is not functioning properly

A tumor is present that interferes with the brain's ability to control FSH production

Anterior Pituitary

Growth Hormone

Effects, Promotes growth of:, Bone, Soft tissue, Viscera, Affects:, Protein synthesis, Glucose transport, Metabolism, Lipolysis

Regulation, Stimulated by GHRH which is affected by:, Sleep, Exercise

Follicle Stimulating Hormone

Effects, Male, Maintains spermatogenesis, Maintains production of sex-hormone binding globulin, Female, Causes development of ovarian follicle, Simulates secretion of estrogen and progesterone

Regulation, Stimulates production of inhibin, Negative feedback on the hypothalamus and pituitary gland

Thyroid Stimulating Hormone

Effects, Causes synthesis of:, T3 hormones, T4 hormones

Regulation, Stimulated by thyroid releasing hormone (TRH) from the hypothalamus, TRH is released when T3 and T4 hormones are low, T3 and T4 exert negative feedback on the production of TSH, Affected by:, Blood levels, Glucose, Metabolic rate

Insufficient Growth Hormone Production

Tests

Blood Tests: Looking for IGF-1 hormone deficiency, IGF-1 hormone is responsible for growth in children and enhancing anabolic affects in adults, such as muscle growth

Measure Weight and Height then extrapolate & compare with suggested growth rate

Symptoms

Adults, May not show any visible symptoms, possible characteristics are shortness, and short appendages

Children, Dwarfism, Abnormally/Unusually low stature or small size, Stunted Growth, Reduced growth rate in human development, Can be onset from malnutrition in children, including malnutrition during fetal development from the mother

Insufficient Thyroid Stimulating Hormone Production

Tests

CT scan, Check thyroid gland and pituitary gland

MRI

Blood test, Look for levels of T3 and T4

X rays

Symptoms

Confusion

Cold intolerance

Weight gain

Constipation

Dry Skin

Hair Loss

Fatigue
