15 Possible Causes for Gonadotrophin Increased, Luteinizing Hormone Low, Testicular Biopsy Abnormal

  • Klinefelter Syndrome

    Furthermore he had increased gonadotrophin levels and an extreme oligoasthenoteratozoospermia (OAT).[ncbi.nlm.nih.gov] Endocrinological examination revealed a high growth hormone (GH) concentration, low testosterone concentration, and high follicle-stimulating hormone and luteinizing hormone[ncbi.nlm.nih.gov] Testicular biopsies of KS infants and boys demonstrated decreased or absent germ cells and abnormal seminiferous tubules ( 16 , 50 – 52 ).[dx.doi.org]

  • Sertoli Cell-Only Syndrome

    […] in the urine is increased.[medical-dictionary.thefreedictionary.com] Plasma testosterone, LH (luteinizing hormone), and FSH (follicle-stimulating hormone) measurements are helpful in separating these conditions.[taldon.org] Human testicular biopsy specimens were obtained from patients suffering from post-testicular infertility (testis showing normal spermatogenesis, 10 cases) and testicular infertility[ncbi.nlm.nih.gov]

  • Hypogonadism

    However, as the testes are impaired or missing, they are not able to respond to the increased levels of gonadotrophins and little or no testosterone is produced.[yourhormones.info] hormone ( 9.4 mU/mL)], secondary (low total testosterone, low/normal luteinizing hormone), primary (low total testosterone, elevated luteinizing hormone) and compensated[ncbi.nlm.nih.gov] If tests confirm that you have low testosterone, further testing can determine if a testicular disorder or a pituitary abnormality is the cause.[mayoclinic.org]

  • Anorchia

    The basal FSH and LH levels were increased, and their increase in response to gonadotrophin-releasing hormone test was prolonged, while testosterone levels failed to increase[ncbi.nlm.nih.gov] Tests include testosterone levels (low); follicle stimulating hormone and luteinizing hormone levels (elevated); X,Y karyotype; ultrasound or magnetic resonance imaging showing[bionity.com] Testicular biopsy is rarely indicated (special fixative required).[rcpa.edu.au]

  • Central Precocious Puberty

    Approximately 1 year after the surgery, the patient's breast development persisted, bone age progressed rapidly, and gonadotropin levels increased in a GnRH test.[ncbi.nlm.nih.gov] 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[ncbi.nlm.nih.gov] A testicular biopsy was not done. Our patient was treated with four cycles of preoperative chemotherapy (cisplatin, alternating with carboplatin/dox-orubicin).[cyberleninka.org]

  • Cryptorchidism

    BACKGROUND: An increase in cryptorchidism has been reported in many countries.[ncbi.nlm.nih.gov] Tests include observable lack of testes, low testosterone levels (typical female levels), elevated follicle stimulating hormone and luteinizing hormone levels, XY karyotype[en.wikipedia.org] More importantly, only testicular biopsy can nowadays determine which patient should benefit from hormonal therapy.[ncbi.nlm.nih.gov]

  • Seminal Vesicle Disorder

    During puberty, the level of a hormone called gonadotrophin-releasing hormone (GnRH) increases. GnRH is produced in a part of the brain called the hypothalamus.[patient.info] These patients usually have low serum luteinizing hormone (LH) levels as well.[auanet.org] Bone growth and increased height. How does the male reproductive system work?[patient.info]

  • Primary Male Hypogonadism

    However, as the testes are impaired or missing, they are not able to respond to the increased levels of gonadotrophins and little or no testosterone is produced.[yourhormones.info] Patients who have demonstrably low levels of luteinizing hormone often need some form of Testosterone Replacement Therapy in order to preserve healthy function.[hgh.tv] These studies may include: Hormone testing Semen analysis Pituitary imaging Genetic studies Testicular biopsy Testosterone testing also plays an important role in managing[nchmd.org]

  • Congenital Absence of the Testis

    The basal FSH and LH levels were increased, and their increase in response to gonadotrophin-releasing hormone test was prolonged, while testosterone levels failed to increase[funpecrp.com.br] Tests include observable lack of testes, low testosterone levels (typical female levels), elevated follicle stimulating hormone and luteinizing hormone levels, XY karyotype[en.wikipedia.org] […] spermatogenesis and should therefore, undergo a diagnostic testicular biopsy.[auanet.org]

  • Infertility

    As a man ages, testosterone levels decrease, gonadotropin levels increase, sperm concentration and semen volume change, and libido decreases.[emedicine.com] hormone levels. 43 Other low-cost methods of monitoring for ovulation, although less effective, include basal body temperature measurements and cervical mucus changes. 42[aafp.org] In some instances, a biopsy of testicular tissue can identify infertility problems such as sperm production, abnormal growths, tumors, or underdeveloped reproductive organs[labtestsonline.org]
