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.

XX gonadal dysgenesis is a type of female hypogonadism in which the ovaries do not function to induce puberty in a person assigned female at birth, whose karyotype is 46,XX. [1] Individuals with XX gonadal dysgenesis have normal-appearing external genitalia as well as Müllerian structures (e.g., cervix, vagina, uterus).
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. A varicocele can reduce hormonal production as well ...
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 ...
Primary amenorrhoea (failure to start menstruation). [8] Poorly defined secondary sexual characteristics. [3] Micropenis in 5-10% of male cases. [2] Cryptorchidism (undescended testicles) at birth. [2] Low levels of the gonadotropins LH and FSH. [3] Hypogonadism due to low levels of testosterone in men or oestrogen/progesterone in women. [3 ...
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.
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.

It’s estimated that nearly 5% of Americans above the age of 12 live with hypothyroidism, a condition that occurs when the body experiences a deficit of thyroid hormone.. The thyroid gland ...
