Predict what would happen to testosterone production in the testes in response to an injection of a large amount of testosterone in an adult male?  :thi:

= decrease in sex hormones i think?  Does anyone know what would happen in a bit more detail?

Predict what anatomical and physiology changes would occur to and adult female who is injected with a large amount of testosterone.  ???

Your body is set up to produce the correct amount of testosterone. Your brain tells your testicles to make it. If you inject it, the brain sees that you have plenty, and stops sending signals to your testicles, and they shut down production. Since they're not being used, they shrivel up.

Here are some side effects of injecting testosterone:

Endocrine and urogenital: Gynecomastia and excessive frequency and duration of penile erections. Oligospermia may occur at high dosages.

Skin and appendages: Hirsutism, male pattern of baldness, seborrhea, and acne.

Fluid and electrolyte disturbances: Retention of sodium, chloride, water, potassium, calcium, and inorganic phosphates.

Gastrointestinal: Nausea, cholestatic jaundice, alterations in liver function tests, rarely hepatocellular neoplasms and peliosis hepatis.

Hematologic: Suppression of clotting factors II, V, VII, and X, bleeding in patients on concomitant anticoagulant therapy, and polycythemia.

Nervous system: Increased or decreased libido, headache, anxiety, depression, and generalized paresthesia.

Allergic: Hypersensitivity, including skin manifestations and anaphylactoid reactions.

Miscellaneous: Inflammation and pain at the site of intramuscular injection.

If you were to inject testosterone into a female, she'd start developing male characteristics and not be able to have a child as it inhibits certain female hormones.

Thanks so much!! =D

Hope it helped!
