The correct sequence of hormones during gametogenesis is as follows : (B) Gonadotropin-releasing hormone from hypothalamus : This is the first step as the hypothalamus releases gonadotropin-releasing hormone (GnRH). (E) Gonadotropins from the anterior pituitary gland : GnRH stimulates the anterior pituitary to release gonadotropins, luteinizing hormone (LH), and follicle-stimulating hormone (FSH). (A) Gonadotropin LH stimulates synthesis and secretion of androgen : LH stimulates the Leydig cells in the testes to produce androgens. (C) Androgen stimulates spermatogenesis : Androgens, such as testosterone, stimulate the process of spermatogenesis. (D) Gonadotropin FSH helps in the process of spermiogenesis : FSH stimulates the Sertoli cells in the testes, which help in the process of spermiogenesis, the transformation of spermatids into mature spermatozoa. So, the correct answer is Option C : (B), (E), (A), (C), (D).
