30 Possible Causes for Gynecomastia, Luteinizing Hormone Low, Testicular Biopsy Abnormal

  • Klinefelter Syndrome

    Gynecomastia is treated surgically because of the potential danger of malignancy or for cosmetic reasons.[] 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 ).[]

  • Leydig Cell Tumor

    Others 20% need surgical treatment of gynecomastia.[] Serum levels of luteinizing hormone (LH) and follicle stimulating hormone (FSH) were inappropriately low for a post-menopausal woman, with high levels of estradiol.[] The gynecomastia was resolved within 3 months after surgery. No recurrence of the tumor has occurred after 10 months.[]

  • Hypogonadism

    Additional features suggest specific disorders, eg, anosmia in Kallmann syndrome; eunuchoid body habitus, gynecomastia, and small testes in Klinefelter syndrome.[] 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.[]

  • Anorchia

Diagnosis of Gynecomastia Figure 1.[] 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).[]

  • Sertoli Cell-Only Syndrome

    Gynecomastia is not present and all masculine characteristics are found normal.[] 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[]

  • Orchitis

    […] containing acid fast bacteria and reduced spermatogenesis Obliterative phase: dense fibrosis, no detectable tubules, reduced vessels, rare acid fast bacteria; associated with gynecomastia[] […] in mumps orchitis, have found low testosterone levels, elevated luteinizing hormone (LH) levels and an exaggerated pituitary response to LH-releasing hormone stimulation[] […] occur in about 13% of patients while 30-87% of patients with bilateral mumps orchitis experience infertility. [10] Studies by Adamopoulos et al. on the levels of various hormones[]

  • Primary Male Hypogonadism

    Increase oestrogen effect on breast tissue What are the causes of gynecomastia?[] 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[]

  • Cryptorchidism

    Tests include observable lack of testes, low testosterone levels (typical female levels), elevated follicle stimulating hormone and luteinizing hormone levels, XY karyotype[] More importantly, only testicular biopsy can nowadays determine which patient should benefit from hormonal therapy.[] Nistal M, Paniagua R, Riestra ML, Reyes-Múgica M, Cajaiba MM: Bilateral prepubertal testicular biopsies predict significance of cryptorchidism-associated mixed testicular[]

  • Feminization

    Here, we report about a 30 years old male subject with vanishing testis syndrome, feminization and gynecomastia.[] Incisional biopsy of abnormal gonads is important, but the diagnosis of testicular feminization must be confirmed by appropriate laboratory tests.[] Abstract A 45-year-old man presented with gynecomastia, hypertension and a large left adrenal mass.[]

  • Androgen Insensitivity Syndrome

    Although tamoxifen has been shown to be fairly safe and effective for idiopathic pubertal gynecomastia, it remains unknown whether it is also beneficial for gynecomastia associated[] Impaired phallic (penile) development due to high estradiol, luteinizing hormone (LH) and follicle stimulating hormone (FSH) relative to the testosterone.[] Testicular biopsy performed on IV 39 discovered dysplasia of the seminiferous tubule, with only a few primary spermatocytes.[]
