Assertion: After puberty, the increased levels of GnRH acts at the posterior pituitary and stimulates the secretion of two gonadotropins LH and FSH.
Reason: LH acts on the Sertoli cells and FSH acts on the Leyding cells.

Identify the statements as correct or incorrect with explanations for your answer (i) FSH acts on the Leydig cells and stimulates synthesis and secretion of androgens. (ii) The increased level of GnRH acts on the anterior pituitary and stimulates the secretion of gonadotropins, i.e. LH and FSH. (iii) The fully grown primary oocyte completes mitotic division producing two daughter nuclei, i.e. secondary oocyte and first polar body. (iv) Ovum is a rounded, motile cell having abundant cytoplasm called ooplasm and a large nucleus termed as germinal vesicle.
