What is the state called when the penis is soft and not erect?
Flaccid.
What is Spermatogenesis?
Spermatogenesis is the production of spermatids.
What role does Aldosterone play in the body?
Aldosterone promotes the reabsorption of salt, which affects blood volume, blood pressure, and hydration.
What does the Parathyroid hormone do?
Parathyroid hormone increases blood calcium levels.
What is Calcitonin and its effect on the body?
Calcitonin helps regulate calcium levels in the bloodstream.
What is the role of Antidiuretic hormone?
Antidiuretic hormone stops urination and helps maintain hydration.
What is Detumescence?
Detumescence is the end of stimulation when blood vessels constrict, compressed veins reopen, and blood flow out, resulting in a flaccid state.
What does the posterior pituitary gland secrete?
The posterior pituitary gland secretes Oxytocin and Antidiuretic hormone.
What is Triiodothyronine (T3) and its function?
Triiodothyronine (T3) influences metabolism, energy production, and various physiological processes in the body.
What is the role of nitric oxide (NO) during erection?
Nitric oxide (NO) causes vasodilation, increasing blood flow into erectile tissues.
What occurs during venous compression in an erection?
As the erectile tissues expand, they compress the surrounding veins, which helps maintain the erection.
What is Thyroxine (T4) and its role?
Thyroxine (T4) influences metabolism, energy production, and various physiological processes in the body.
What is the function of Oxytocin?
Oxytocin tells smooth muscles to contract, inducing uterine contractions and milk ejection in the breast.
What are releasing hormones (RH) and what do they do?
Releasing hormones stimulate the release of other hormones.
What is the function of Cortisol?

What happens to the erectile tissues during an erection?
Blood fills the corpora cavernosa and the corpus spongiosum, but not too much to keep the urethra open.
What is Spermiogenesis?
Spermiogenesis is the transformation of spermatids into sperm cells.
What is the function of Growth Hormone?
Growth hormone increases protein synthesis.
What are Androgens?
Androgens are male sex hormones.
What triggers an erection?
Arousal signals from the brain trigger the release of nitric oxide (NO).
What are stimulating hormones (SH) and their functions?
Stimulating hormones (S) stimulate, increase, decrease, or suppress the activity of other hormones.
