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 ...
XY complete gonadal dysgenesis, also known as Swyer syndrome, is a type of defect hypogonadism in a person whose karyotype is 46,XY. Though they typically have normal vulvas, [1] the person has underdeveloped gonads, fibrous tissue termed "streak gonads", and if left untreated, will not experience puberty.
In men, it causes impaired muscle and body hair development, gynecomastia, decreased height, erectile dysfunction, and sexual difficulties. If hypogonadism is caused by a disorder of the central nervous system (e.g., a brain tumor), then this is known as central hypogonadism.
Hypergonadotropic hypogonadism (HH), also known as primary or peripheral/gonadal hypogonadism or primary gonadal failure, is a condition which is characterized by hypogonadism which is due to an impaired response of the gonads to the gonadotropins, follicle-stimulating hormone (FSH) and luteinizing hormone (LH), and in turn a lack of sex steroid production.

The rate of Klinefelter syndrome among infertile males is 3.1%. The syndrome is the main cause of male hypogonadism. [68] One survey in the United Kingdom found that the majority of people with KS identify as male, however, a significant number have a different gender identity. [69] The prevalence of KS is higher than expected in transgender ...
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 ...
[10] In males, a type of myopathy can result from androgen deficiency known as testosterone deficiency myopathy or (hypogonadotropic) hypogonadism with myopathy. Signs and symptoms include elevated serum CK , symmetrical muscle wasting and muscle weakness (predominantly proximal ), a burning sensation in the feet at night, waddling gait , and ...
The degree of development of the male reproductive tract is determined by the ratio of germ line cells expressing the XY genotype. [ 21 ] [ 23 ] Manifestations of mixed gonadal dysgenesis are highly variable with asymmetry in gonadal development of testis and streak gonad, accounted for by the percentage of cells expressing XY genotype.
