Which of the following statements about oogenesis and spermatogenesis is correct?
A
Follicle-stimulating hormone (FSH) promotes egg but not sperm development.
B
Luteinizing hormone (LH) triggers ovulation in females but is not important in males.
C
Gonadotropin-releasing hormone (GnRH) triggers the anterior pituitary to release FSH and LH in males but not females.
D
Primary oocytes and primary spermatocytes follow a similar pattern of development through meiosis.
E
The principal sex hormones in both males and females are steroid hormones.
Verified step by step guidance1
Understand the process of oogenesis and spermatogenesis: Oogenesis is the process of egg formation in females, while spermatogenesis is the process of sperm formation in males. Both processes involve meiosis, but they have distinct differences in timing and regulation.
Examine the role of hormones: Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are crucial in regulating reproductive processes. FSH stimulates the growth of ovarian follicles in females and is also important for sperm production in males. LH triggers ovulation in females and stimulates testosterone production in males.
Analyze the role of Gonadotropin-releasing hormone (GnRH): GnRH is released by the hypothalamus and stimulates the anterior pituitary gland to release FSH and LH in both males and females, not just in males.
Compare the development of primary oocytes and primary spermatocytes: Both primary oocytes and primary spermatocytes undergo meiosis, but the timing and outcome differ. In females, oogenesis results in one mature egg and polar bodies, while in males, spermatogenesis results in four viable sperm cells.
Identify the principal sex hormones: In both males and females, the principal sex hormones are steroid hormones. In males, testosterone is the primary hormone, while in females, estrogen and progesterone are the main hormones.
