In as much detail as possible, hand draw a schematic diagram of the hypothalamic-pituitary- gonad (HPG) axis in the human male. Be sure to include all the relevant structures and hormones. You must define all abbreviations the first time you use them. Please include (and explain) the feedback loops.

A negligence action was brought by a mother against a hospital on behalf of her minor daughter. It alleged that when the mother was 13 years of age, the hospital negligently transfused her with Rh-positive blood. The mother's Rh-negative blood was incompatible with and sensitized by the Rh-positive blood. The mother discovered her condition 8 years later during a routine blood screening ordered by her healthcare provider in the course of prenatal care. The resulting sensitization of the mother's blood allegedly caused damage to the fetus, resulting in physical defects and premature birth. Did a patient relationship with the transfusing hospital exist?
