Hypogonadotropic hypogonadism (HH), is due to problems with either the hypothalamus or pituitary gland affecting the hypothalamic-pituitary-gonadal axis (HPG axis). [1] Hypothalamic disorders result from a deficiency in the release of gonadotropic releasing hormone ( GnRH ), while pituitary gland disorders are due to a deficiency in the release ...
In females, functional hypogonadotropic hypogonadism (FHH) (or functional hypothalamic amenorrhea) is part of the differential diagnosis for GnRH insensitivity. The presence of predisposing factors like excessive exercise , weight loss , or psychological stress point towards the diagnosis of FHH rather than GnRH insensitivity.
It is normally difficult to distinguish a case of Kallmann syndrome (KS)/hypogonadotropic hypogonadism (HH) from a straightforward constitutional delay of puberty. However, if puberty has not started by either age 14 (girls) or 15 (boys) years and one or more of the non-reproductive features mentioned below is present, then a referral to ...
As women with FHA work to correct energy balance, especially female athletes and those recovering from eating disorder, recovery from hypogonadotropic hypogonadism may occur in a series of phases; there can be stages where the luteal phase is inadequate or may display lower sex steroid and gonadotropin levels for many years.

Isolated hypogonadotropic hypogonadism (IHH), also called idiopathic or congenital hypogonadotropic hypogonadism (CHH), as well as isolated or congenital gonadotropin-releasing hormone deficiency (IGD), is a condition which results in a small subset of cases of hypogonadotropic hypogonadism (HH) due to deficiency in or insensitivity to gonadotropin-releasing hormone (GnRH) where the function ...
The symptoms of hypogonadotrophic hypogonadism, a subtype of hypogonadism, include late, incomplete or lack of development at puberty, and sometimes short stature or the inability to smell; in females, a lack of breasts and menstrual periods, and in males a lack of sexual development, e.g., facial hair, penis and testes enlargement, deepening ...
The fertile eunuch syndrome or Pasqualini syndrome is a cause of hypogonadotropic hypogonadism caused by a luteinizing hormone deficiency. [1] It is characterized by hypogonadism with spermatogenesis. [2] Pasqualini and Bur published the first case of eunuchoidism with preserved spermatogenesis in 1950 in la Revista de la Asociación Médica ...
These characteristics are known as hypogonadotropic hypogonadism. Females are rarely affected by this disorder, but a few cases have been reported of adrenal insufficiency or a lack of female sex hormones, resulting in underdeveloped reproductive tissues, delayed puberty, and an absence of menstruation.
