Difference Between FSH And LH

In men, the testicles and in women, the ovaries are involved in the production of sex hormones. The brain uses two hormones, FSH and LH, to control the levels of sex hormones in the body.

Simultaneous monitoring of sex hormones and LH and FSH levels will ultimately give the treatment team an accurate picture of an individual’s hormonal status. As a result, find out why a person’s bloodstream may be deficient in high levels of sex hormones.

Key Difference – FSH vs LH

Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are commonly referred to as gonadotropins. They are involved in the stimulation of germ cells in the production of gametes in both males and females. Both hormones are essential for the reproductive processes that the body does. They are synthesized and secreted by gonadotropic cells of the anterior pituitary gland. FH stimulates the formation of gametes that occur in the primary genitalia, while LH is not involved. This is the main difference between FSH and LH.

What is FSH?

Follicle-stimulating hormone (FSH) is a hormone that is involved in the growth and development of the body and regulates puberty and various reproductive processes. FSH is a polypeptide hormone. It is generally considered to be a gonadotropin. Gonadotropins secrete FSH into the posterior pituitary gland. FSH affects both men and women. It mainly involves the maturation of male and female germ cells. In women, FSH has many functions.

The amount of FSH in the blood is very different from the concentration of follicle-stimulating hormone in men and women. The age of a person also affects the amount. Keep in mind that in women, the amount of this hormone changes with the menstrual cycle.

Only the amount of FSH can be important. However, coupled with the results of sex hormone tests (testosterone in men, progesterone and estrogen in women), this can actually be interpreted. The FSH test is done with blood. It is better not to do this test for menstruating women. If you are taking oral contraceptives, the test results will not be accurate. It is best to inform the laboratory and your doctor before taking a sample.

What is LH?

Luteinizing hormone (LH) is produced by gonadotropin cells in the anterior pituitary gland. LH is secreted by the pituitary gland and regulated by gonadotropin-releasing hormone. LH is a heterogeneous glycoprotein. Each monomer unit is composed of glycoprotein molecules containing alpha and beta that form a fully functional protein.

In women, teca cells in the womb help LH. The LH surge produces the corpus luteum and begins ovulation. In men, LH is called stromal cell stimulating hormone (ICSH). This lactic acid stimulates cell testosterone production.

Difference Between FSH And LH

Here is the list of common differences between LH and FSH.

Difference between FHS And LH

FSH (Follicle Stimulating Hormone)

  • FSH controls the development of primary sex organs.
  • It stimulates gamete formation in primary sex organs.
  • Follicle Stimulating Hormone stimulates the secretion of estrogen by growing Graafian follicle.
  • It controls the first half of the ovarian or menstrual cycle.
  • The hormone does not have any major role in ovulation.
  • It does not help in the synthesis of androgens.
  • FSH does not act on the corpus luteum.

LH (Luteinsing Hormone)

  • LH has no role in the development of primary sex organs.
  • It has no effect on the formation of gametes.
  • It does not do so.
  • Luteinising Hormone controls the second half of the menstrual cycle.
  • The hormone is required for ovulation.
  • LH acts on Leydig cells and helps produce androgens.
  • It sustains the development of the corpus luteum and its secretory activity.

What are the similarities between FSH and LH?

  • Both FSH and LH work synergistically with each other.

FSH vs LH
Follicle-stimulating hormone (FSH) is a polypeptide hormone involved in the regulation of growth and development, puberty, and various reproductive processes in the body.Luteinizing hormone (LH) is a hormone produced by gonadotrophic cells of the anterior pituitary gland
Development of primary genitalia
FSH is involved in the development of the primary genitalia.LH does not have specific functions during the development of the primary genitalia.
Gamete formation
The formation of gametes is stimulated by FSH, which occurs in the primary genitalia.LH is not involved in the formation of gametes.
Menstrual cycle
The first half of the menstrual cycle is controlled by FSH.The second half of the menstrual cycle is controlled by LH.
Secretions of estrogon
FSH stimulates the secretion of estrogen.LH does not stimulate the secretion of estrogen.
ovulation
FSH does not participate in the process of ovulation.LH is an important hormone during ovulation.
Effects on the corpus luteum
FSH does not affect the corpus luteum.LH is involved in the development of the corpus luteum, especially during the secretory phase.
Androgen Production
FSH does not affect the production of androgens.LH acts on Leydig cells, which stimulate the production of androgens.

Final Words

Hope you get the same what you are looking for. If you find it useful, share it with your besties. Still, have any queries feel free to write us in the comment section.

FSH and LH are gonadotropins because they are synthesized and secreted by gonadotropic cells in the anterior pituitary gland. LH is considered a heterodimeric glycoprotein. There are glycoprotein molecules in each of the monomer units with one alpha and one beta that make up a fully functional protein.

Follicle-stimulating hormone is a hormone involved in the regulation of growth and development, puberty, and various reproductive processes present in the body. FSH is a polypeptide hormone, and LH is considered a heterodimeric glycoprotein. This is the difference between FSH and LH. Both FSH and LH work synergistically with each other.
