This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Pubeal Changes, Subject name: Gynaecology & Obstetrics
Normal stature with minimal or absent pubeal development may be seen in: 
Select and explain. 
A. Testicular feminization, B. Kallmann syndrome, C. Pure gonadal dysgenesis, D. Turner syndrome
B: Kallmann syndrome
Answer: B: Kallmann syndrome 
Explanation: Testicular feminization is a syndrome of androgen insensitivity, characterized by a normal 46 XY genotype; normal female phenotype during childhood; tall stature; and "normal" breast development with absence of axillary and pubic hair. Gonadal dysgenesis (e.g., 45X Turner syndrome) is characterized by sho stature and absence of pubeal development; in these girls, the ovaries are either absent or streak gonads that are non-functional. Kallmann syndrome (hypogonadotropic hypogonadism) should be suspected in patients of normal stature with delayed or absent pubeal development, especially when associated with the classic finding of anosmia. These individuals have a structural defect of the CNS involving the hypothalamus and the olfactory bulbs. The hypothalamus does not secrete GnRH in normal pulsatile fashion, if at all.
