Which of these is not produced by the placenta?

  • A. estrogen
  • B. relaxin
  • C. progesterone
  • D. lactogen
Correct Answer: B

Rationale: The correct answer is B: relaxin. The placenta produces estrogen, progesterone, and lactogen to support pregnancy. Relaxin is primarily produced by the corpus luteum and later by the placenta. However, it is not exclusively produced by the placenta, making it the correct choice. Estrogen is crucial for fetal development and maintaining pregnancy. Progesterone helps in preparing the uterus for implantation and supporting the pregnancy. Lactogen (human placental lactogen) plays a role in regulating maternal metabolism and fetal growth.
