Sinisi, A. Anosmia can be easily diagnosed by questioning the patient, whereas olfactometry, such as University of Pennsylvania Smell Identification Test, is necessary to determine reliably whether olfaction is normal or partially defective.

Efficacy trials have focused on improvement in sexual function and have demonstrated hyoogonadotropic compared to placebo in this area. Volume In secondary hypogonadism, an issue in the hypothalamus or pituitary gland results in decreased GnRH, LH, and FSH, resulting in decreased sex hormone production despite normal testes or ovaries. The preservation of muscular strength and lean body mass are related to androgens, as is bone hemostasis, which prevents osteoporosis. Raivio, T.
