297 Possible Causes for Luteinizing Hormone Low

  • Hypogonadotropic Hypogonadism Type 22

    His laboratory investigations showed low luteinizing hormone (LH), follicle stimulating hormone (FSH), and testosterone levels.[]

  • Hypogonadism

    hormone ( 9.4 mU/mL)], secondary (low total testosterone, low/normal luteinizing hormone), primary (low total testosterone, elevated luteinizing hormone) and compensated[] 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[] […] performed a cross-sectional study enrolling 786 consecutive Caucasian-European infertile men segregated into eugonadal [normal serum total testosterone ( 3.03 ng/mL) and normal luteinizing[]

  • Polycystic Ovary Syndrome

    hormone, follicle-stimulating hormone, total cholesterol, low-density lipoprotein C or insulin.[] hormone, follicle‐stimulating hormone, total cholesterol, low‐density lipoprotein C or insulin.[] Low levels of luteinizing hormone can also cause infertility, because insufficient levels will limit the production of sperm or the ovulation process.[]

  • Toxoplasmosis

    Other laboratory test results showed low sodium, thyrotropin, FT4, FT3, cortisol levels, corticotropin, luteinizing hormone, and testosterone.[]

  • Endocrine Dysfunction

    Gonadotrophin responsiveness to luteinizing hormone releasing hormone (LHRH) paralleled the clinical evidence of puberty, or its lack.[] Serum total thyroxine was normal in every patient, while serum total triiodothyronine was low in six; in these six patients serum triiodothyronine normalised with treatment[]

  • Vasomotor Instability

    The second group of six women had a high mean interpulse interval frequency of 3.5 /- 0.34 and a low mean amplitude of 12.2 /- 1.8 IU/L luteinizing hormone pulses.[] RESULTS: Analysis of gonadotropin pulses revealed a single pattern of plasma follicle-stimulating hormone but two distinct patterns of luteinizing hormone frequency and amplitude[] CONCLUSION: There are subgroups of postmenopausal women with different patterns of luteinizing hormone pulsatility.[]

  • Hypothyroidism

    In addition to a low TSH, central hypothyroidism may be associated with deficiencies of other hormones, including: Growth hormone Adrenocorticotropic hormone, which stimulates[] […] the adrenal gland during stress Luteinizing and follicle-stimulating hormone, which control ovary and testicular function Prolactin, which helps females produce milk Oxytocin[]

  • Klinefelter Syndrome

    Endocrinological examination revealed a high growth hormone (GH) concentration, low testosterone concentration, and high follicle-stimulating hormone and luteinizing hormone[] A physical examination revealed small testes and thin pubic hair, laboratory examination found high luteinizing hormone (LH) and follicle stimulating hormone (FSH) levels[] Testosterone, follicle-stimulating hormone, luteinizing hormone, and inhibin B levels were determined. Large testicular nodules were removed.[]

  • Endometriosis

    While administration of high doses of RU486 in the mid- or late follicular phase delays the luteinizing hormone (LH) surge and inhibits ovulation, low doses can cause infertility[]

  • Orchitis

    […] 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.
