low doses and are gradually increased according to the body responses. Most of the studies regarding estrogen therapy have focused on girls with Turner Syndrome. There are many formulations for estrogen therapy that include oral estradiol, oral conjugated estrogen, transdermal estrogen patches, and estrogen gel. The therapy is individualized and is initiated based on many factors including age, bone age, absolute height, and psychosocial issues. Progesterone therapy for a week per month in addition to estrogen allows for adequate uterine and breast development. Routine follow-ups for during and after pubertal inductions can include checkups for height, weight, body-mass index (BMI), and blood pressure three times a year and FSH/LH measurements every year.

As individuals progress onto adolescence, they may experience absent or delayed puberty or puberty that starts but fails to progress. Adult males with HH may exhibit gynecomastia, erectile dysfunction, reduced testicular volume (absence of testicular enlargement during puberty), abnormal testicular texture and consistency, small stature, decreased libido and sexual activity, infertility due to low ( 422:
testosterone replacement therapy. However, it is important to note that testosterone treatment does not restore fertility in men. There are many infertility treatment options available for individuals with HH, such as selective estrogen receptor modulators (SERMs), aromatase inhibitors (AIs), and gonadotropins. Testicular sperm extraction, intracytoplasmic sperm injections, semen/embryo cryopreservation are also possible treatment options .

hypogonadism. Neonatal testosterone therapy can be given to infants with HH. However, for children, testosterone should be avoided due to the possible adverse effects of rapid bone aging and growth acceleration. There are various formulation of testosterone including oral, intramuscular, and transdermal such as patches and gels. Testosterone therapy should be avoided in individuals with breast and/or prostate cancer.

Females may present with low levels of estrogen and abnormal menstruation. Individuals with Turner syndrome may have short stature, dysmorphic features, gonadal dysgenesis, and delayed puberty. Other signs and symptoms associated with HH consist of intellectual disability or learning difficulties and

In females with HH, estrogen therapy is done initially for breast development and pubertal induction. Pubertal induction should start no later than the age of 12 to maximize height growth and for benefits to outweigh adverse effects. Estrogen therapy, commonly using ethinylestradiol, should start at

Individuals with hypergonadotropic hypogonadism also exhibit gonadotropin levels (FSH and LH) that are above normal range and gonadal hormone levels (estrogen in females and testosterone in males) that are below normal range, so these biochemical parameters will be measured via a blood test. However

Hypergonadotropic hypogonadism can be caused by a variety of genetic and acquired factors. Common genetic causes include Turner syndrome and Klinefelter syndrome, while acquired causes may involve infections, trauma, radiation, or chemotherapy affecting the gonads.

can also be done to evaluate for any chromosomal abnormalities. Blood tests to check levels of prolactin, iron and thyroid hormones can be done to diagnose HH. Semen analysis can be another way to measure the sperm count to help diagnose individuals with HH.
