The association of anosmia with gonadal failure was first described by Kallmann et al. and reviewed by Nawakouski and Lenz. This hypogonadotropic hypogonadism is due to a defect of the hypothalamic level.
We reported a case of Kallmann`s syndrome who was visited our department for evaluation of undescended testis. The patient was 15 year old male with anosmia and underdeveloped external genitalia.
Hormonal study was done. On basal state. FSH was 1.1 mIU/ml, LH and testosterone were undetectable. 24 hours urine 17-OH CS is 4.5 mg/dl. After LH-RH 100μg was intravenous administration. LH value was 3.9mIU/ml. 2.0mIU/ml. 1.7mIU/ml. 1.0mIU/ml on 30’. 60’, 90’, 120’, respectively and FSH value was 3.8mIU/ml, 4.0mIU/ml, 4.9mIU/ml, 4.0mIU/ml on 30’, 60’, 90’. 120’, respectively.
