Poor pituitary production of LH is thought to be implicated in obesity-associated testosterone deficiency. One study revealed that altering a BMI from 30 to 25 kg/m2 could result in a 13 percent ...
The underlying cause is due to the defective migration of GNRH neurons from olfactory placode to hypothalamus, leading to congenital GNRH deficiency. This leads to olfactory problems such as anosmia, optic defects like color blindness, and results in hypothalmic deficiencies associated with low levels of LH, affecting sex hormone testosterone ...
