Somatostatin
/hormones/somatostatin/
Somatostatin is a hormone that inhibits the secretion of several other hormones, including growth hormone, thyroid stimulating hormone, cholecystokinin and insulin.

Cushing's disease
/endocrine-conditions/cushing-s-disease/
Cushing's disease is the collection of clinical symptoms and signs resulting from a pituitary tumour that causes excessive amounts of the hormone cortisol to be released by the adrenal glands.

Multiple endocrine neoplasia type 1
/endocrine-conditions/multiple-endocrine-neoplasia-type-1/
Multiple endocrine neoplasia type 1 is a rare inherited disease, which can result in tumours in the pituitary and parathyroid glands, and pancreas.

Hypopituitarism
/endocrine-conditions/hypopituitarism/
Hypopituitarism is the failure of production of one or more hormones from the pituitary gland.

Dehydroepiandrosterone
/hormones/dehydroepiandrosterone/
Dehydroepiandrosterone is an important precursor hormone, and is the most abundant circulating steroid present in the human body. It has little biological effect on its own but has powerful effects when converted into other hormones such as sex steroids.

Hirsutism
/endocrine-conditions/hirsutism/
Hirsutism is the presence of excess male-pattern hair growth in women and is commonly caused by an imbalance of hormones.

Adrenocorticotropic hormone
/hormones/adrenocorticotropic-hormone/
Adrenocorticotropic hormone (ACTH) is produced by the pituitary gland. Its key function is to stimulate the production and release of cortisol from the cortex (outer part) of the adrenal gland.

Familial medullary thyroid cancer
/endocrine-conditions/familial-medullary-thyroid-cancer/
Familial medullary thyroid cancer is a rare inherited form of thyroid cancer.

Primary hyperaldosteronism
/endocrine-conditions/primary-hyperaldosteronism/
Primary hyperaldosteronism refers to a condition in which one or both adrenal glands generate too much of a hormone called aldosterone. This causes sodium (salt) retention, leading to high blood pressure.

Male contraceptives
/topical-issues/male-contraceptives/
There is a great deal of ongoing research into developing new male contraceptive options. However, currently, the only available male contraceptive options are undergoing a surgical procedure called a vasectomy and using a condom.

Placenta
/glands/placenta/
The placenta is a temporary endocrine organ formed during pregnancy, which produces hormones important in the maintenance of a healthy pregnancy and in preparation for labour and breastfeeding.

Addison's disease
/endocrine-conditions/addison-s-disease/
Addison's disease is caused by damage to the adrenal glands, which make hormones to control multiple metabolic processes in the body, and balance body salt and water. Treatment is with hormone replacement tablets and some lifestyle adaptations to ensure patients remain well.

Obesity
/endocrine-conditions/obesity/
Obesity is an excess of calories stored in the form of fat. It is an increasing public health and medical problem associated with reduced quality and length of life.

Resistance to thyroid hormone is a rare genetic condition where some body tissues do not respond normally to thyroid hormones produced by the thyroid gland. It may be associated with no symptoms or with features of both an overactive and underactive thyroid.
