Read the following statements regarding the endocrine functions of human reproductive structures: (A) Leydig cells synthesise and secrete testicular hormones called androgens. (B) The corpus luteum secretes large amounts of estrogens which is essential for the maintenance of the endometrium. (C) The placenta acts as an endocrine tissue and produces human chorionic gonadotropin (hCG) and human placental lactogen (hPL)

Step-by-step solution

Statement (A) is correct as Leydig cells (interstitial cells) synthesise and secrete androgens (mainly testosterone). Statement (B) is incorrect because the corpus luteum secretes large amounts of progesterone, not estrogens, which is essential for the maintenance of the endometrium. Statement (C) is correct as the placenta acts as an endocrine tissue producing hCG, hPL, estrogens, and progestogens. Statement (D) is incorrect because growing ovarian follicles primarily secrete estrogens, whereas progesterone is mai
