Describe one function of each of the following mammalian reproductive hormones: (i) FSH (ii) Progesterone (iii) Testosterone.
Worked Solution & Example Answer:Describe one function of each of the following mammalian reproductive hormones: (i) FSH (ii) Progesterone (iii) Testosterone. - Leaving Cert Agricultural Science - Question (j) - 2017
Step 1
(i) FSH
Answer
Follicle-stimulating hormone (FSH) plays a crucial role in reproductive physiology by promoting the development of ovarian follicles in females, which is essential for egg maturation. In males, FSH is vital for spermatogenesis, aiding in the production and maturation of sperm cells.
Step 2
(ii) Progesterone
Answer
Progesterone serves important functions in the reproductive cycle. It primarily inhibits ovulation during the luteal phase of the menstrual cycle. Additionally, it plays a key role in maintaining pregnancy by preventing uterine contraction and supporting the implantation of embryos.
Step 3
(iii) Testosterone
Answer
Testosterone is critical for the development of male secondary sexual characteristics, such as increased muscle and bone mass, and body hair growth. Furthermore, it is essential for stimulating spermatogenesis in the testes, ensuring the production of viable sperm.
