688 Possible Causes for Luteinizing Hormone Low, Precocious Female Puberty, Testicular Biopsy Abnormal

  • Central Precocious Puberty

    With respect to female central precocious puberty, approximately 80%-90% have no underlying pathology.[] Although basal levels of luteinizing hormone and follicle-stimulating hormone are low, similar to what is expected in the pre-pubertal period, testosterone levels are high[] A testicular biopsy was not done. Our patient was treated with four cycles of preoperative chemotherapy (cisplatin, alternating with carboplatin/dox-orubicin).[]

  • Leydig Cell Tumor

    Children typically present with precocious puberty.[] Serum levels of luteinizing hormone (LH) and follicle stimulating hormone (FSH) were inappropriately low for a post-menopausal woman, with high levels of estradiol.[] Due to excess testosterone secreted by the tumour, one-third of female patients present with a recent history of progressive masculinization.[]

  • Klinefelter Syndrome

    Endocrinological examination revealed a high growth hormone (GH) concentration, low testosterone concentration, and high follicle-stimulating hormone and luteinizing hormone[] Testicular biopsies of KS infants and boys demonstrated decreased or absent germ cells and abnormal seminiferous tubules ( 16, 50 – 52 ).[] A physical examination revealed small testes and thin pubic hair, laboratory examination found high luteinizing hormone (LH) and follicle stimulating hormone (FSH) levels[]

  • Hypogonadotropic Hypogonadism Type 22

    […] of puberty Delayed sexual development E30.1 Precocious puberty Precocious menstruation Excludes: Albright(-McCune)(-Sternberg) syndrome ( Q78.1 ) central precocious puberty[] His laboratory investigations showed low luteinizing hormone (LH), follicle stimulating hormone (FSH), and testosterone levels.[] Elevated follicle-stimulating hormone (FSH) or luteinizing hormone (LH) levels suggest an ovarian abnormality (hypergonadotropic hypogonadism).[]

  • Sertoli Cell-Only Syndrome

    Plasma testosterone, LH (luteinizing hormone), and FSH (follicle-stimulating hormone) measurements are helpful in separating these conditions.[] Human testicular biopsy specimens were obtained from patients suffering from post-testicular infertility (testis showing normal spermatogenesis, 10 cases) and testicular infertility[] METHODS: Testicular samples were obtained from 5 men with pure SCOS on biopsy during TESE and from 5 cadaveric men with normal spermatogenesis.[]

  • Familial Male-Limited Precocious Puberty

    Females with mutations associated with familial male-limited precocious puberty appear to be unaffected.[] […] secretion of luteinizing hormone (LH) has been low, whether measured by radioimmunoassay or bioassay, 1, 2 and there is no response to the suppressive effects of the potent[] […] the context of low luteinizing hormone.[]

    hormone ( 9.4 mU/mL)], secondary (low total testosterone, low/normal luteinizing hormone), primary (low total testosterone, elevated luteinizing hormone) and compensated[] If tests confirm that you have low testosterone, further testing can determine if a testicular disorder or a pituitary abnormality is the cause.[] Men with hypogonadotropic hypogonadism, or HH, have abnormally low levels of luteinizing hormone, or LH, and follicle-stimulating hormone, or FSH, two hormones produced by[]
