Answer:
Luteinizing Hormone or LH is not produced by the human placenta.
Option (d).
Explanation:
LH is used by the anterior pituitary gland. It is also known as the gonadotrophic hormone. It controls the reproductive system. It regulates the functioning of testes in males and ovaries in females.
Pituitary Gland is "smaller" in size but known as the "master gland". Pituitary Gland can be split into two parts, the "anterior pituitary gland" and the "posterior pituitary gland". The hormone produced by the anterior pituitary gland is "adrenocorticotropic hormone", growth hormone, LH and FSH. It then releases them into the bloodstream.
