  2. Hypopituitarism - Wikipedia

    en.wikipedia.org/wiki/Hypopituitarism

    Hypopituitarism is the decreased (hypo) secretion of one or more of the eight hormones normally produced by the pituitary gland at the base of the brain. [1] [2] If there is decreased secretion of one specific pituitary hormone, the condition is known as selective hypopituitarism. [3]

  3. Hypothalamic–pituitary–gonadal axis - Wikipedia

    en.wikipedia.org/wiki/Hypothalamic–pituitary...

    The synthetic progestin prevents the hypothalamus from releasing GnRH and the pituitary from releasing LH and FSH; therefore it prevents the ovarian cycle from entering the menstrual phase and prevents follicle development and ovulation. Also as a result, many of the side effects are similar to the symptoms of pregnancy.

  4. Hypothalamic disease - Wikipedia

    en.wikipedia.org/wiki/Hypothalamic_disease

    Hypothalamic disease is a disorder presenting primarily in the hypothalamus, which may be caused by damage resulting from malnutrition, including anorexia and bulimia eating disorders, [1] [2] genetic disorders, radiation, surgery, head trauma, [3] lesion, [1] tumour or other physical injury to the hypothalamus. The hypothalamus is the control ...

    The failure to breastfeed and amenorrhea no more periods, were seen as the syndrome (a collection of symptoms), but we now view Sheehan's as the pituitary failing to secrete 1-5 of the 9 hormones that it normally produces (the anterior (front) lobe of the pituitary produces FSH, LH, prolactin, ACTH (Adreno-cortico-trophic hormone),TSH (Thyroid ...

    en.wikipedia.org/wiki/Pituitary_apoplexy

    Many pituitary tumors (25%) are found to have areas of hemorrhagic infarction on MRI scans, but apoplexy is not said to exist unless it is accompanied by symptoms. [ 1 ] [ 4 ] In some instances, lumbar puncture may be required if there is a suspicion that the symptoms might be caused by other problems ( meningitis or subarachnoid hemorrhage ).

  7. Follicle-stimulating hormone - Wikipedia

    en.wikipedia.org/wiki/Follicle-stimulating_hormone

    Follicle-stimulating hormone (FSH) is a gonadotropin, a glycoprotein polypeptide hormone. [1] FSH is synthesized and secreted by the gonadotropic cells of the anterior pituitary gland [2] and regulates the development, growth, pubertal maturation, and reproductive processes of the body.

  8. Hypothalamic–pituitary hormone - Wikipedia

    en.wikipedia.org/wiki/Hypothalamic–pituitary...

    Hypothalamic–pituitary hormones are hormones that are produced by the hypothalamus and pituitary gland. Although the organs in which they are produced are relatively small, the effects of these hormones cascade throughout the body.

  9. 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.
