29 Possible Causes for Luteinizing Hormone Low, Testicular Atrophy, Testicular Biopsy Abnormal

  • Klinefelter Syndrome

    ) Those with absence of germ cells, but without testicular atrophy, germinal epithelium is affected. 5.[] 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 ).[]

  • Orchitis

    Patient may observe an altered size of the testis, which can be small (testicular atrophy) or large (testicular enlargement).[] […] in mumps orchitis, have found low testosterone levels, elevated luteinizing hormone (LH) levels and an exaggerated pituitary response to LH-releasing hormone stimulation[] The criteria for testicular atrophy have been set according to the contralateral testicular volume reduction of 20% or 2ml.[]

  • Sertoli Cell-Only Syndrome

    Maturation arrest, sertoli cell only syndrome (SCOS), and testicular atrophy were exclusively associated with azoospermia.[] 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[]

  • Leydig Cell Tumor

    […] of Testicular Leydig Cell Tumors depend on whether it is a benign or malignant tumor.[] Serum levels of luteinizing hormone (LH) and follicle stimulating hormone (FSH) were inappropriately low for a post-menopausal woman, with high levels of estradiol.[] atrophy, infertility; also germline mutations in fumarate hydratase ( J Clin Endocrinol Metab 2006;91:3071 ), hereditary leiomyomatosis and renal cell carcinoma Rarely due[]

  • Cryptorchidism

    atrophy, whether unilateral or, and this is a much more serious event, bilateral. 2016 The Author(s) Published by S.[] Tests include observable lack of testes, low testosterone levels (typical female levels), elevated follicle stimulating hormone and luteinizing hormone levels, XY karyotype[] Testicular atrophy occurs in less than 5% of boys after unilateral orchidopexy.[]

  • Primary Male Hypogonadism

    Of 41 men, 10 had reduced libido or impotence and 6 had testicular atrophy.[] Patients who have demonstrably low levels of luteinizing hormone often need some form of Testosterone Replacement Therapy in order to preserve healthy function.[] These studies may include: Hormone testing Semen analysis Pituitary imaging Genetic studies Testicular biopsy Testosterone testing also plays an important role in managing[]

  • Hypogonadism

    Testicular atrophy: Are my balls shrinking?[] 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.[]

  • Congenital Absence of the Testis

    Bilateral testicular atrophy may be caused by either primary or secondary testicular failure.[] Tests include observable lack of testes, low testosterone levels (typical female levels), elevated follicle stimulating hormone and luteinizing hormone levels, XY karyotype[] […] levels Bone density Follicle stimulating hormone ( FSH ) and luteinizing hormone ( LH ) levels Surgery to look for male reproductive tissue Testosterone levels (low) Ultrasound[]

  • Anorchia

    These were sited in the scrotum at orchidopexy but had subsequently atrophied. Endocrine tests confirmed absent testicular function.[] Tests include testosterone levels (low); follicle stimulating hormone and luteinizing hormone levels (elevated); X,Y karyotype; ultrasound or magnetic resonance imaging showing[] Testicular biopsy is rarely indicated (special fixative required).[]

  • Germ Cell Tumor

    When EGCT is suspected, sonographic and physical examination of the testicles should be performed to evaluate for testicular lesion or atrophy; negative testicular ultrasound[] Her serum hormonal assay revealed a low estradiol level with elevated luteinizing hormone and follicular stimulating hormone levels with normal progesterone and testosterone[] Many patients with extragonadal germ cell tumors have histories of infertility, and testicular biopsy in these patients shows various abnormalities, including decreased spermatogenesis[]
