Question

Which of the following hormone is not secreted by placenta?

• A. HCG
• B. HPL
• C. Relaxin
• D. Estrogen, progesterone

Hint:

Major placental hormones (NCERT): \[ \boxed{ \begin{aligned} &HCG\\ &HPL\\ &Estrogen\\ &Progesterone \end{aligned} } \] Remember: \[ \boxed{\text{Placenta = HCG + HPL + Estrogen + Progesterone}} \] These hormones maintain pregnancy and promote fetal development.

Answer 1

The Correct Option is C

The placenta functions as a temporary endocrine organ secreting hCG, human placental lactogen (hPL), estrogen, and progesterone to maintain pregnancy. Luteinizing hormone (LH) and follicle-stimulating hormone (FSH) are not secreted by the placenta; these gonadotropins are produced by the anterior pituitary gland.
