Can hypogonadism cause delayed puberty?

Approximately 20% of delayed puberty is due to functional hypogonadotropic hypogonadism, in which puberty is delayed in onset but occurs spontaneously and progresses normally once begun. Permanent hypogonadotropic or hypergonadotropic hypogonadism accounts for 25% of cases (see Box 10-1).

How is delayed puberty diagnosed?

Delayed puberty is absence of sexual maturation at the expected time. Diagnosis is by measurement of gonadal hormones (testosterone and estradiol), luteinizing hormone, and follicle-stimulating hormone. Treatment, when necessary, usually involves specific hormone replacement.

What is LHRH stimulation test?

The LHRH test is being done because there is concern about either early puberty or delayed puberty. It will help your doctor find out the cause of the early onset or delay. The medicine we give your child during the test stimulates the pituitary gland so it will make the hormones found in puberty.

How does GnRH stimulation test work?

Gonadotropin-releasing hormone (GnRH) stimulation tests assess activation of the hypothalamic-pituitary-gonadal axis (HPG axis). Administering GnRH analogues (GnRHa), together with determination of serum basal and poststimulated gonadotropin levels, predicts pubertal responses at pubertal ages.

Can delayed puberty be treated?

If the delayed puberty is inherited, no treatment is usually needed. In some cases, treatment may be done with hormone therapy. This helps to cause secondary sexual characteristics to occur. In other cases, surgery may be done to correct a physical problem.

How do you fix delayed puberty?

If the delayed puberty is inherited, no treatment is usually necessary. In some cases, treatment may involve hormone therapy to stimulate the development of secondary sexual characteristics, or surgery to correct an anatomical problem.

How is LHRH test done?

During the test A small needle called a cannula will be inserted into a vein in your arm or hand. This allows your nurse to take blood samples directly, without further use of needles. After you have had a blood sample taken we will give you an injection of gonadotrophin- releasing hormone (GnRH) through the cannula.

What will happen if GnRH production is blocked?

In men, the lack of gonadotropins will mean the testes will not grow at puberty and they will not produce their own testosterone and sperm. In women, the lack of gonadotropins will mean the ovaries will not release mature eggs and they will not produce oestrogen or progesterone and menstruation will not occur.

Can you test for GnRH?

LH response to GnRH is a blood test to help determine if your pituitary gland can correctly respond to gonadotropin releasing hormone (GnRH). LH stands for luteinizing hormone.

When should I be worried about delayed puberty?

Boys can start puberty at a wide range of ages, with 95% starting between the ages of 9 and 14, so we consider puberty delayed when it has not started by age 14. The growth spurt usually starts a year or so after the genitals start to enlarge, generally by age 15.
