Study Notes
Hormone Regulation
- Luteinizing hormone (LH) stimulates Leydig's cells to synthesize testosterone in males.
- Follicle-stimulating hormone (FSH) stimulates sperm production in males.
Hormone Functions
- LH stimulates theca cells in females.
- GnRH (Gonadotropin-releasing hormone) activates the hypothalamic pituitary gonadal (HPG) axis, sensitizing the pituitary gland.
- Somatostatin reduces growth hormone secretion and is used to treat acromegaly.
Reproductive System
- FSH and LH stimulate the production of mature eggs in the ovaries.
- GnRH agonists are used to manipulate the hypothalamic pituitary gonadal axis.
Menopause and Fertility
- Follicle-stimulating hormone (FSH) is used to confirm postmenopausal age in women.
- The primary function of GnRH agonist in fertility treatment is to suppress gonadotropin release, allowing for controlled ovarian stimulation.
Hormone Interactions
- GnRH agonist increases LH and FSH production, but not insulin-like growth factor-1 (IGF-1).
- Gonadotropins (LH and FSH) play a crucial role in the reproductive system, stimulating gamete production.
- The hypothalamic pituitary gonadal (HPG) axis includes GnRH, LH, FSH, and sex steroids.
Pregnancy and Treatment
- GnRH agonist is not suitable for ovarian hyperstimulation syndrome treatment.
- Thyrotropes (thyrotrophs) in the anterior pituitary lobe stimulate thyroid-stimulating hormone (TSH) production, regulating thyroid function.
Studying That Suits You

Description
Test your knowledge on the role of gonadotropins in normal growth, sexual development, and reproduction, as well as their interaction with the hypothalamic pituitary gonadal (HPG) axis. Explore how periodic pulses of gonadotrophin-releasing hormone (GnRH) regulate the involved endocrine organs for a specific CNS response.
