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 ...
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.

Contrast with a young woman or teen, who would have hypogonadism rather than menopause. This is because hypogonadism is an abnormality, whereas menopause is a normal change in hormone levels. In any case, the LH and FSH levels will rise in cases of primary hypogonadism or menopause, while they will be low in women with secondary or tertiary ...
To distinguish it from other forms of hypogonadotropic hypogonadism, Kallmann syndrome has the additional symptom of a total lack of sense of smell (anosmia) or a reduced sense of smell. [ 2 ] [ 3 ] [ 4 ] If left untreated, people will have poorly defined secondary sexual characteristics , show signs of hypogonadism , almost invariably are ...
In females, the positive feedback loop between estrogen and luteinizing hormone help to prepare the follicle in the ovary and the uterus for ovulation and implantation. When the egg is released, the empty follicle sac begins to produce progesterone to inhibit the hypothalamus and the anterior pituitary thus stopping the estrogen-LH positive ...
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 ...
Menopause is associated with lower estrogen and thus is associated with hair loss." An older 2006 study of mice and skin cells indicated that estrogen can affect hair growth.
Primary ovarian insufficiency (premature menopause) due to varying causes, such as radiation therapy, chemotherapy, or a spontaneous manifestation, can also lead to low estrogen and infertility. [17] Hypogonadism (a condition where the gonads – testes for men and ovaries for women – have diminished activity) can decrease estrogen. [18]
