Hypogonadism resulting from defects of the gonads is referred to as hypergonadotropic hypogonadism or primary hypogonadism. Examples include Klinefelter syndrome and Turner syndrome . Mumps is known to cause testicular failure, and in recent years has been immunized against in the US.
Primary hypogonadism is a form of testicular failure in which the testicles fail to produce enough testosterone despite strong stimulation from the pituitary gland.
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. [1]
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 ...
Late-onset hypogonadism (LOH) or testosterone deficiency syndrome (TDS) [1] [2] is a term for a condition in older men characterized by measurably low testosterone levels and clinical symptoms mostly of a sexual nature, including decreased desire for mating, fewer spontaneous erections, and erectile dysfunction. [3]
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 ...
While ED is commonly associated with aging, it doesn’t mean men 65 and older have to suffer from dysfunction. ... Male hypogonadism (low testosterone production) is a common age-related issue ...
46,XX gonadal dysgenesis is characteristic of female hypogonadism with a karyotype of 46,XX. [8] Streak ovaries are present with non-functional tissues unable to produce the required sex steroid oestrogen. [9] Low levels of oestrogen effect the HPG axis with no feedback to the anterior pituitary to inhibit the secretion of FSH and LH. [9]
