BIOS256 OL, Week 6 Lab
Name:
OL Lab 6: Male and female reproductive system
Learning objectives:
Identify the process of gametogenesis
Describe the hormonal regulation in male and female reproductive cycle.
Identify the male and female reproductive structures.

system. (5 points)

Name:
1.2 Identify the function of the following hormones: (4 points)
a. Gonadotropin-releasing hormone (GnRH): responsible for promoting sexual
development by stimulating the secretion of LH and FSH
b. Follicle stimulating hormone: helps control menstrual cycles and production of eggs by
the ovries
c. Luteinizing hormone – Stimulates the interstitial cells of Leydig to produce androgenic
hormones/testosterone.
d. Inhibin – in males, inhibin acts to reduce FSH release from the anterior pituitary gland
e. Dihydrotestosterone (DHT) – responsible for the same effects as testosterone, but plays
more significant role in the development of secondary sexual characteristics, including
the enlargement of the sex organs and development of facial hair/deepening of the
voice.
f. Testosterone – responsible for the development of the secondary sexual characteristics
during puberty, such as deepening of the voice, the growth of facial hair, and muscle
development, stimulates and maintains maturation of the male reproductive organs and
secretory glands, and stimulates production/development of spermatozoa by stimulating
