Here are the correct matches for the hormones with their sources:
-
GnRH (Gonadotropin-Releasing Hormone)
- Source: Hypothalamus (not Neurohypophysis)
-
Testosterone
- Source: Interstitial Cells (Leydig cells in the testes)
-
FSH (Follicle-Stimulating Hormone)
- Source: Adenohypophysis (anterior pituitary gland)
-
Inhibin
- Source: Sustentacular Cells (Sertoli cells in the testes; also produced by the ovaries, but in this context, refers to Sertoli cells)
So, the corrected match for GnRH should be identified as coming from the Hypothalamus instead of the Neurohypophysis.
