Predict the effect of steroid hormone dosing on pituitary hormone production and steroid synthesis in the ovaries or teste

Solution

Answer= Steroid hormones are any group of harmones that belongs to the class of chemical compounds known as steroids

They are secreted by 3 steroid glands Adrenal cortex , testes , ovaries

Adrenal cortex produces 1] Glucocorticoids = Such as cortisol controls many metabolic processes such as formamation of glucose from fatty acids

2] Mineralocorticoids such as aldosterone

ACTH of pituitary gland stimulates growth & secretion of these hormones

Hyposecretion of ACTH leads to Addisons disease

Hypersecretion leads to excessive growth of adrenal cortex causes cushings disease

Steroid synthesis in

Testis = Androgens are male sex hormones synthesized in testes

Androgens also have anabolic functions in stimulating the production of sketetal muscles bones as well as red blood cells

To enhance anabolic activity of androgens without increasing their masculizing abilityanabolic steroids were develoved

These synthetic hormones abused by individuals desiring to increase their muscle mass

Overdosing leads to severe side effects including infertility & coronary heart diseases

OVARY = synthesizes estrogens

Progestrin & estrogens are used as oral contraceptive by women to prevent pregnancy

causes intermenstrual spotting ,breast tenderness ,nausea etc.
