Hypogonadism can involve just hormone production or just fertility, but most commonly involves both. [citation needed] Examples of hypogonadism that affect hormone production more than fertility are hypopituitarism and Kallmann syndrome; in both cases, fertility is reduced until hormones are replaced but can be achieved solely with hormone ...
As of 2016, the International Society for the Study of the Aging Male defines late-onset hypogonadism as a series of symptoms in older adults related to testosterone deficiency that combines features of both primary and secondary hypogonadism; the European Male Aging Study (a prospective study of ~3000 men) [10] defined the condition by the presence of at least three sexual symptoms (e.g ...
Testosterone is the primary androgen — or male hormone — in your body. Low testosterone affects up to 39 percent of adult men in the US over the age of 45, and becomes increasingly prevalent ...
The rate of Klinefelter syndrome among infertile males is 3.1%. The syndrome is the main cause of male hypogonadism. [67] 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. [68] The prevalence of KS is higher than expected in transgender ...
46,XY gonadal dysgenesis is characteristic of male hypogonadism with karyotype 46,XY. [12] In embryogenesis, the development of the male gonads is primarily controlled by the testis determining factor located on the sex-determining region of the Y chromosome . [12]
In 1914, Franz Weidenreich performed autopsies on cadavers of 10 people who had had anosmia, uncovering hypogonadism in three and postulating a syndromic association. [ 11 ] The syndrome is named for Franz Josef Kallmann , a German - American geneticist , who, along with colleagues, described three family clusters of the syndrome in a 1944 ...
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 ...
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.
