  • Consider MRI if workup suggests hypothalamic or pituitary mass or other abnormality (eg, abnormal pituitary hormone levels, visual field lesions, or neurologic signs). Testicular ultrasound if testicular masses are detected on examination.[hiv.va.gov]
  • In both women and men, LH is often used in conjunction with other tests ( FSH, testosterone, estradiol and progesterone ): In the workup of infertility To aid in the diagnosis of pituitary disorders that can affect LH production To help diagnose conditions[labtestsonline.org]
Testosterone Increased
  • In the good response group, serum luteinizing hormone and follicle-stimulating hormone levels increased to the normal range, total serum testosterone increased from 0.29 nmol/L to 8.67 nmol/L ( P .00002), and testicular volume increased from 3.3 mL to[healio.com]


  • More studies are needed in infertile male patients with LH variants to demonstrate if recombinant LH or hCG treatment could be beneficial in selected populations.[austinpublishinggroup.com]
  • Luteinizing Hormone Deficiency Treatment Treatment options can be directed at the hypogonadism on its own or the pituitary dysfunction.[healthhype.com]
  • Treatment Medical Care Hypogonadotropic hypogonadism Treatment of hypogonadotropic hypogonadism depends on the gender and age of the patient as well as their desire for current fertility.[emedicine.medscape.com]
  • Apart from the demographic data, anamnestic details e.g. reason for the infertility, duration of the unfulfilled wish for children, past medical treatment for conception and accompanying illnesses will be documented.[clinicaltrials.gov]

  • When considering pathology related to the pituitary itself, the most common etiology of either over- or under-production of pituitary hormones in adults is a pituitary lesion.[clinicaladvisor.com]
