  1. Hormone的應用

  2. 使用於繁殖方面的 hormone (1)刺激腦下垂體前葉的分泌 (2)取代前葉gonadotrophins的作用 (3)estrogens (4)progesterones (5)prostaglandin (6)melatonin。

  3. GnRH 隱睪?

  4. GnRH

  5. GnRH

  6. LH and FSH are released into the systemic circulation, traveling to the target reproductive organs (testes and ovary) where sex steroid hormones are controlled. LH sends the same message and results in increased testosterone production by the testis due to LH effect on the Leydig cells of the testis.

  7. FSH/PMSG 隱睪?

  8. FSH/PMSG

  17. PGF2

  18. vascular uteroovarian pathways forPGF2α • Local uteroovarian：如牛羊，其路徑經子宮肌肉到子宮靜脈、靜脈叢，再滲透進入卵巢動脈。 • System uteroovarian：如馬兔，其路徑經子宮肌肉到子宮靜脈、體循環達肺臟，再經體循環進入卵巢動脈。 • Combined system and local uteroovarian：如豬、天竺鼠、蒼鼠及大白屬，若切除一邊子宮角，則黃體仍可停留一段時間，但不超過一個週期以上。

  19. vascular uteroovarian pathways forPGF2α Systemic uteroovarian pathway: Local uteroovarian pathway: Combined systemic and local uteroovarian pathway: horse, rabbit sheep, cattle, swine, guinea pig, swine hamsters, rats
