- Leptin.
- Estradiol.
- Androgen.
- Luteinizing Hormone.
- Follicle-Stimulating Hormone.
- Gonadotropin.
- Kisspeptin.

What is hypothalamus pituitary gonadal?
The hypothalamic-pituitary-gonadal axis (HPG axis) alludes to the connection between the hypothalamus, pituitary gland, and gonads. It is an important control mechanism mainly involved in the development and regulation of the reproductive system and immune system. It is also involved in the aging process.
What is part of the hypothalamic-pituitary-gonadal axis?
The hypothalamic-pituitary-gonadal (HPG) axis coordinates a tightly regulated feedback loop that consists of gonadotropin-releasing hormone (GnRH) produced by the hypothalamus; follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary; and the sex steroids estrogen, progesterone, and …
What hormones link the hypothalamus the pituitary gland and the female gonads?
How the female gonadal axis works
- The hypothalamus secretes GnRH.
- GnRH travels down to the anterior pituitary gland and binds to receptors on the gland.
- This promotes the release of LH (luteinizing hormone) and FSH (follicle-stimulating hormone).
- LH and FSH travel in the bloodstream to the ovaries.
Which hormone released from the hypothalamus regulates gonad function?
Gonadotropin-releasing hormone (GnRH)
Gonadotropin-releasing hormone (GnRH) secreted from the hypothalamus regulates the secretion of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the pituitary, and then FSH and LH act on the gonads to stimulate gonadal development and maturation.
What is the relationship between hypothalamus pituitary and gonad involved in producing testosterone?
Gonadotropin-releasing hormone (GnRH) is secreted from the hypothalamus by GnRH-expressing neurons. The anterior portion of the pituitary gland produces luteinizing hormone (LH) and follicle-stimulating hormone (FSH), and the gonads produce estrogen and testosterone.
What are LH and FSH?
Luteinizing hormone (LH) plays a key role in gonadal function. LH in synergy with follicle stimulating hormone (FSH) stimulates follicular growth and ovulation. Thus, normal follicular growth is the result of complementary action of FSH and LH. FSH is frequently used in assisted reproductive technology (ART).
Which hormone from the pituitary gland is responsible to activate gonads?
Gonadotropin-releasing hormone (GnRH) secreted from the hypothalamus regulates the secretion of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the pituitary, and then FSH and LH act on the gonads to stimulate gonadal development and maturation.
What do the hypothalamus and pituitary gland regulate?
The hypothalamus links the nervous and endocrine systems by way of the pituitary gland. Its function is to secrete releasing hormones and inhibiting hormones that stimulate or inhibit (like their names imply) production of hormones in the anterior pituitary.
Which hormone from pituitary gland is responsible to activate gonads?
What is the androgen hormone?
Androgens are the group of sex hormones that give men their ‘male’ characteristics (collectively called virilisation). The major sex hormone in men is testosterone, which is produced mainly in the testes.
What are the two gonadal hormones?
Male Gonad Hormones Androstenedione – These are the hormones that act as a precursor to estrogens and testosterone. Inhibin – These hormones inhibit the release of FSH and thought to be involved in sperm cell regulation and development.
What hormones do the pituitary gland produce?
Anatomy of the Pituitary Gland
- Human growth hormone (HGH or GH)
- Thyroid-stimulating hormone (TSH)
- Adrenocorticotrophin hormone (ATCH)
- Follicle-stimulating hormone (FSH)
- luteinizing hormone (LH)
- prolactin.
What hormones are produced by the pituitary gland?
What is estrogen and androgen?
Descriptions. Androgens and estrogens are hormones. Estrogens are produced by the body in greater amounts in females. They are necessary for normal sexual development of the female and for regulation of the menstrual cycle during the childbearing years. Androgens are produced by the body in greater amounts in males.
What is the function of LH hormone?
LH is made by your pituitary gland, a small gland located underneath the brain. LH plays an important role in sexual development and functioning. In women, LH helps control the menstrual cycle. It also triggers the release of an egg from the ovary.
Which of the following is a gonadal hormone?
Gonadal hormones – nearly always synonymous with gonadal steroids – are hormones produced by the gonads, and include both steroid and peptide hormones. The major steroid hormones include estradiol and progesterone from the ovaries, and testosterone from the testes.
