FSH And LH Stimulation By Gonadotropin-Releasing Hormone

This test aids in detecting the accuracy of the working of your pituitary gland. It diagnoses whether the development and working of the child's pituitary gland are delayed or early. This test is often hated by patients as this needs multiple samples at different times and is time-wasting. It is expensive for an ordinary middle-class man.

What is the pituitary Gland?

It is one of the essential glands of the human body. It is a small pea-sized land at the base of the skill. It constitutes a significant part of the endocrine system. It secretes various hormones like Gonadotropin-releasing hormones.

What is Gonadotropin-releasing Hormone?

This is a reproductive hormone that is released by the pituitary gland. These hormones help in the maturation and functioning of sex glands.

What role does GnRH play in females?

The female sex hormones are:

• Estrogen
• Progesterone

GnRH indirectly stimulates these hormones. These hormones help in Ovulation and in getting pregnant. The production of estrogen elevates the levels of GnRH during the menstrual cycle. This increase in GnRH tends to decrease the FSH, and the LH is increased. These steps result in the formation of eggs in the ovary.

The following is the Role of GnRH in males

The sex hormones produced by males are.

• Testosterone 
•  Androgens

They are affected by LH, which GnRH ultimately secretes. Even Sperm production is affected by FSH, which GnRH also secretes

Various Factors Affecting the GnRH

GnRH levels are elevated to peak when puberty hits an adolescent and is low during childhood days. Also, when the number of sex hormones is released more by the body, GnRH levels are decreased.

What do increased levels of GnRH cause?

Elevated levels of GnRH can lead to

• Pituitary Adenomas 
• Early Puberty

What do decreased levels of GnRH cause?

Low levels of GnRH can cause:

• Abnormal menstruation
• Absence of ovulation
• Delayed sexual maturation Female infertility.
• Low sex drives

Special Requirement before Test

This test needs no special requirements. The only condition for this test is to get it done during certain days of the menstrual cycle.

No fast is needed.

The procedure of the Test:

• Initially, a blood sample is taken by the lab technician.
• Many samples are taken at different times.
• The ultimate sample is taken after 24 hours.
• The sample is then sent to the lab and examined in the laboratory.

Interpretation of Result

If the levels are elevated, it indicates early puberty.
