Melanocyte-stimulating hormone describes a group of hormones produced by the pituitary gland, hypothalamus and skin cells. It is important for protecting the skin from UV rays, development of pigmentation and control of appetite.
Melatonin is mainly produced by the pineal gland and, although it appears not to be essential for human physiology, it is known to have a range of different effects when taken as a medication.
Male hypogonadism is the result of deficiency of the male sex hormone testosterone. It can lead to loss of sex drive and function, delayed puberty, osteoporosis, and there can also be associated failure of the testes to produce sperm.
The menopause is the time when menstruation stops because the ovaries stop producing hormones and releasing eggs for fertilisation. This marks the end of a woman's reproductive years.
Goitre is a general term for an enlarged thyroid gland. Multinodular goitre is where the enlarged thyroid appears with a number of separate lumps (nodules) in the gland.
Multiple endocrine neoplasia type 1 is a rare inherited disease, which can result in tumours in the pituitary and parathyroid glands, and pancreas.
Multiple endocrine neoplasia type 2A (MEN2A) is a rare inherited disease causing the development of tumours in the thyroid, adrenal and parathyroid glands.
Multiple endocrine neoplasia type 2B (MEN2B) is a rare inherited disease causing the development of tumours in the thyroid, adrenal and parathyroid glands, and mucosal tumours.
The increase in prevalence of individuals who are obese or develop metabolic complications like cardiovascular disease, diabetes and non-alcoholic fatty liver disease (NAFLD) is increasing. The development of these diseases is a result of a several of symptoms which are collectively known as metabolic syndrome.

a general feeling of not being very well.
not eating properly; not receiving enough nutrients.
tissue in female breasts that produces milk during lactation (breastfeeding).
a rare genetic disorder which causes overactivity of glands in the body, as well as characteristic skin and bony abnormalities. The overactivity is caused by a change in the protein that usually controls hormone production.
the inner area of an organ; e.g. kidney, thyroid, adrenal gland.
describes the inner area of an organ; e.g. thyroid gland, kidney, adrenal gland.
the (roughly) 28-day cycle of a woman’s reproductive system, which is controlled by female reproductive hormones. Menstruation (period) is at Day 1 and an egg is released at Day 14 (ovulation).

(metaiodobenzylguanidine) a specialised type of nuclear medicine scan used during the investigation of a phaeochromocytoma or paraganglioma (tumours of the sympathetic nervous system).
involving specialists from more than one area of medicine. Some diseases are complex and affect more than one part of the body and so require doctors from different backgrounds to work together to form a treatment plan.
a spontaneous permanent change to the genetic code (DNA) that sometimes results in offspring having a different characteristic to parents or sometimes causes no noticeable effect at all.
(multiple myeloma) a type of cancer that affects plasma cells, a type of white blood cell made in the bone marrow.
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.
The menstrual cycle is an important process that prepares the body for the possibility of pregnancy. Each stage is driven by reproductive hormones that are regulated by the pituitary gland.
Pupils make their own ‘body clock medallion’ to take home. They will learn what hormones are involved in some key bodily functions in a 24-hour period. This activity is designed for students aged 8-12 and is a craft activity designed to stimulate discussion around hormonal control of everyday biological processes.
The menopause marks one of the biggest natural shifts in hormones for women and can bring with it a number of unpleasant symptoms. But is there a testosterone-based equivalent in men?
