Which of the following hormones is not a secretion product of human placenta?

  1. Estrogen
  2. Progesterone
  3. Prolactin
  4. Human chorionic gonadotropin

Answer

(3) Prolactin

Solution

As per NCERT, the placenta also acts as an endocrine tissue and produces several hormones like human chorionic gonadotropin (hCG), human placental lactogen (hPL), estrogens, progestogens, etc.

⇒ Estrogen, progesterone and hCG are therefore placental secretions.

∵ Prolactin is secreted by the anterior pituitary, not by the placenta.

∴ Prolactin is not a secretion product of the human placenta.
