    en.wikipedia.org/wiki/Hypogonadotropic_hypogonadism

    Hypogonadotropic hypogonadism (HH), is due to problems with either the hypothalamus or pituitary gland affecting the hypothalamic-pituitary-gonadal axis (HPG axis). [1] Hypothalamic disorders result from a deficiency in the release of gonadotropic releasing hormone ( GnRH ), while pituitary gland disorders are due to a deficiency in the release ...

    This occurs in an estimated 10 to 22% of people, primarily cases of normosmic congenital hypogonadotropic hypogonadism (CHH) rather than KS cases and only found in people who have undergone some form of testosterone replacement therapy. It is only normally discovered when testicular volume increases while on testosterone treatment alone and ...

    In males, a type of myopathy can result from androgen deficiency known as testosterone deficiency myopathy or (hypogonadotropic) hypogonadism with myopathy. Signs and symptoms include elevated serum CK , symmetrical muscle wasting and muscle weakness (predominantly proximal ), a burning sensation in the feet at night, waddling gait , and ...

    In men, it causes impaired muscle and body hair development, gynecomastia, decreased height, erectile dysfunction, and sexual difficulties. If hypogonadism is caused by a disorder of the central nervous system (e.g., a brain tumor), then this is known as central hypogonadism.

  6. Fertile eunuch syndrome - Wikipedia

    en.wikipedia.org/wiki/Fertile_eunuch_syndrome

    The fertile eunuch syndrome or Pasqualini syndrome is a cause of hypogonadotropic hypogonadism caused by a luteinizing hormone deficiency. [1] It is characterized by hypogonadism with spermatogenesis. [2] Pasqualini and Bur published the first case of eunuchoidism with preserved spermatogenesis in 1950 in la Revista de la Asociación Médica ...

  7. Enclomifene - Wikipedia

    en.wikipedia.org/wiki/Enclomifene

    Enclomiphene is primarily used as a treatment for men with persistent low testosterone as a result of secondary hypogonadotropic hypogonadism. In secondary hypogonadotropic hypogonadism, the resulting low levels of testosterone is attributed to inadequacies in the hypothalamic-pituitary-gonadal axis. In contrast, primary hypogonadism is caused ...

  8. Hypergonadotropic hypogonadism - Wikipedia

    en.wikipedia.org/wiki/Hypergonadotropic_hypogonadism

    Hypergonadotropic hypogonadism (HH), also known as primary or peripheral/gonadal hypogonadism or primary gonadal failure, is a condition which is characterized by hypogonadism which is due to an impaired response of the gonads to the gonadotropins, follicle-stimulating hormone (FSH) and luteinizing hormone (LH), and in turn a lack of sex steroid production. [1]

    Isolated hypogonadotropic hypogonadism (IHH), also called idiopathic or congenital hypogonadotropic hypogonadism (CHH), as well as isolated or congenital gonadotropin-releasing hormone deficiency (IGD), is a condition which results in a small subset of cases of hypogonadotropic hypogonadism (HH) due to deficiency in or insensitivity to gonadotropin-releasing hormone (GnRH) where the function ...
