The presence of anosmia is suggestive of Kallmann syndrome, and if the child is too young to undergo olfaction tests, magnetic resonance imaging MRI scan showing absent or abnormal olfactory bulbs or sulci strongly suggests the diagnosis. IGF-I can be used to evaluate the somatotropic axis, whereas secondary adrenal deficiency can be assessed by measuring a morning cortisol and ACTH.

INTRODUCTION

Erectile dusfunction is a common symptom in patients without hypogonadism and may need treatment in addition to testosterone. Diagnostic methods Diagnosis is based on clinical evaluation of the hypogonadism and hormone testing to confirm gonadotropin deficiencies FSH and LH caused by GnRH deficiency. This article has been cited by other articles in PMC.

The standard range given is based on widely varying ages and, given that testosterone levels naturally decrease as hypogonadism symptoms age, age-group specific averages should be taken into consideration when discussing treatment between doctor and patient.

In such cases, the stimulation of sperm production requires treatment with human chorionic gonadotropin hCG alone or combined with recombinant FSH, urinary FSH or human menopausal gonadotropins hMG. IHH is characterized by low levels of gonadotropins and sex steroids in the absence of anatomical or functional abnormalities of the hypothalamic—pituitary—gonadal axis.
