Step 1: Understanding Gonadotropins.
Gonadotropins are hormones secreted by the anterior pituitary that act on the gonads (testes and ovaries) to regulate reproduction.
Step 2: Key hormones.
The main gonadotropins are FSH (Follicle Stimulating Hormone) and LH (Luteinizing Hormone).
Step 3: Function of FSH.
FSH stimulates spermatogenesis in males and follicular development in females.
Step 4: Function of LH.
LH triggers ovulation in females and testosterone production in males.
Step 5: Other hormones.
GH, LTH, TSH, ACTH, and MSH act on other tissues and are not gonadotropins.
Step 6: Conclusion.
Therefore, FSH and LH are the correct gonadotropins.
