Full Answer
Hormones that stimulate the gonads to produce sex hormones are known as gonadotropins. The pituitary secretes the gonadotropins luteinizing hormone (LH) and follicle-stimulating hormone (FSH). These protein hormones influence reproductive organs in various ways.
Gonads: Hormonal Regulation Sex hormones may be regulated by other hormones, by glands and organs, and by a negative feedback mechanism. Hormones that regulate the release of other hormones are called tropic hormones. Gonadotropins are tropic hormones that regulate the release of sex hormones by gonads.

Gonads are the male and female primary reproductive organs. The male gonads are the testes and the female gonads are the ovaries. These reproductive system organs are necessary for sexual reproduction as they are responsible for the production of male and female gametes.
Oestrogen is considered to be the 'female' hormone, whereas testosterone is considered the 'male' hormone. However, both hormones are present in both sexes.

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.
In both males and females, FSH stimulates gamete production and LH stimulates production of hormones by the gonads.
The male gonads are testes, and the female gonads are the ovaries. They both function to pro- duce gametes (eggs and sperm) and sex hormones.
Male Gonad Hormones Androgens, also known as the 'male hormone' is responsible for the maturation of the male reproductive system. Testosterone: These hormones are essential for the growth of bone, muscle and body hair and are produced by testes.
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).
In men, LH stimulates testosterone production from the interstitial cells of the testes (Leydig cells). FSH stimulates testicular growth and enhances the production of an androgen-binding protein by the Sertoli cells, which are a component of the testicular tubule necessary for sustaining the maturing sperm cell.
pituitary glandFSH is made by your pituitary gland, a small gland located underneath the brain. FSH plays an important role in sexual development and functioning. In women, FSH helps control the menstrual cycle and stimulates the growth of eggs in the ovaries.
This test measures the level of luteinizing hormone (LH) in your blood. 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.
The principle regulator of LH and FSH secretion is gonadotropin-releasing hormone (GnRH, also known as LH-releasing hormone). GnRH is a ten amino acid peptide that is synthesized and secreted from hypothalamic neurons and binds to receptors on gonadotrophs.
Estrogen and progesterone are steroid hormones that play a pivotal role in the regulation of mammalian reproduction. One primary action of these hormones is to regulate the development and function of the uterus. These hormones act by regulating the transcription of specific genes in the uterus.
Hormones that regulate the release of other hormones are called tropic hormones . Gonadotropins are tropic hormones that regulate the release of sex hormones by gonads.
Androstenedione —Androgen hormone that serves as a precursor to testosterone and estrogens. Activin —Hormone that stimulates the production and release of follicle-stimulating hormone (FSH). It also assists in menstrual cycle regulation. Inhibin —Hormone that inhibits the production and release of FSH.
LH stimulates the testes to secrete the sex hormone testosterone and the ovaries to secrete progesterone and estrogens. FSH aids in the maturation of ovarian follicles (sacs containing ova) in females and sperm production in males. The primary hormones of the ovaries are estrogens and progesterone.
Gonads are the male and female primary reproductive organs. The male gonads are the testes and the female gonads are the ovaries. These reproductive system organs are necessary for sexual reproduction as they are responsible for the production of male and female gametes . Gonads also produce sex hormones needed for the growth and development ...
Gonadal hormone production is regulated by hormones secreted by the anterior pituitary in the brain. Hormones that stimulate the gonads to produce sex hormones are known as gonadotropins. The pituitary secretes the gonadotropins luteinizing hormone (LH) and follicle-stimulating hormone (FSH) .
When fertilization is complete, the united sperm and ovum become a zygote. A zygote is a cell that is at the earliest stage of embryonic development. A woman will continue to produce eggs until menopause.
The production of sperm cells is known as spermatogenesis . This process occurs continuously and takes place within the male testes. The male germ cell or spermatocyte undergoes a two-part cell division process called meiosis. Meiosis produces sex cells with one half the number of chromosomes as the parent cell.
Gonads are the reproductive glands in an organism that is responsible for producing sex cells and sex hormones in living beings. Gonads are present in both male and female bodies. Male gonads are referred to as the testicles or the testes which produce testosterone (male sex hormone).
The gonads or reproductive glands in males and females produce gametes (sex cells) and sex hormones. Both men and women produce different sex hormones and these hormones are responsible for reproductive development in individuals. The hormones that stimulate the glands for the production of sex hormones are referred to as gonadotropins.
The male and female gonads perform various functions throughout the body of an individual. The major functions of gonads are as follows:
The process through which male gamete is produced is known as spermatogenesis.
