Please answer the questions below are about the Hypothalamic Pituitary Gonadal Axis (HPG Axis).
1. Generally, when a dog is neutered the veterinarian removes the testicles. How does this procedure alter the secretion of GnRH, LH and FSH?
2. The pituitary gland is found in the sella turcica of the sphenoid bone. It is attached to the brain by a thin stalk made up of blood vessels and nervous tissue. A traumatic brain injury can result in the stalk being torn from the brain. If this occurs how would testosterone secretion be affected?
3. If an athlete is injecting testosterone what happens to GnRH, LH and FSH secretion?
4. When a male athlete injects testosterone the testicles generally get smaller. Why does this occur?
5. What happens to spermatogenesis when a male athlete injects testosterone?
6. GnRH agonists are used to treat women with endometriosis. How would testosterone secretion be affected in the short term and in the long term?
7. When a female gets pregnant the corpus luteum of the ovary secretes progesterone. What happens to GnRH, LH, and FSH during pregnancy?
