Hypogonadism means diminished functional activity of the gonads—the testicles or the ovaries—that may result in diminished production of sex hormones.Low androgen (e.g., testosterone) levels are referred to as hypoandrogenism and low estrogen (e.g., estradiol) as hypoestrogenism.
This leads to olfactory problems such as anosmia, optic defects like color blindness, and results in hypothalmic deficiencies associated with low levels of LH, affecting sex hormone testosterone in males or estrogen and progesterone in females. Diagnosis normally occurs during teenage years when puberty fails to start. [4]
Hypoestrogenism, or estrogen deficiency, refers to a lower than normal level of estrogen. It is an umbrella term used to describe estrogen deficiency in various conditions.

Aromatase deficiency is a rare condition characterized by extremely low levels or complete absence of the enzyme aromatase activity in the body. [2] It is an autosomal recessive disease resulting from various mutations of gene CYP19 (P450arom) which can lead to ambiguous genitalia and delayed puberty in females, continued linear growth into adulthood and osteoporosis in males and virilization ...

Estrogen insensitivity syndrome (EIS), or estrogen resistance, is a form of congenital estrogen deficiency or hypoestrogenism [2] which is caused by a defective estrogen receptor (ER) – specifically, the estrogen receptor alpha (ERα) – that results in an inability of estrogen to mediate its biological effects in the body. [3]
The most common cause is low levels of estrogen (hypoestrogenism), which may result from chronic disease, radiation or chemotherapy, Poland syndrome, extreme physical activity, or gonadal dysgenesis. Amastia, which occurs when a child is born without glandular breast tissue, is rare. [3]
