Question: Which of the following hormones exerts its effect primarily on the reproductive organs?

Hormones of the Anterior Pituitary:

The anterior pituitary is also known as adenohypophysis. The hormones produced by the anterior pituitary are the growth hormone (GH) or somatotropin, prolactin (PRL), adrenocorticotrophic hormone (ACTH), thyroid-stimulating hormone (TSH), follicle-stimulating hormone (FSH), and luteinizing hormone (LH).

What hormones does my pituitary gland produce?

The anterior pituitary gland produces the following hormones and releases them into the bloodstream:

  • adrenocorticotropic hormone, which stimulates the adrenal glands to secrete steroid hormones, principally cortisol
  • growth hormone, which regulates growth, metabolism and body composition
  • luteinising hormone and follicle stimulating hormone, also known as gonadotrophins. They act on the ovaries or testes to stimulate sex hormone production, and egg and sperm maturity
  • prolactin, which stimulates milk production
  • thyroid stimulating hormone, which stimulates the thyroid gland to secrete thyroid hormones.

Each of these hormones is made by a separate type of cell within the pituitary gland, except for follicle stimulating hormone and luteinising hormone, which are made together by the same cell.

Two hormones are produced by the hypothalamus and then stored in the posterior pituitary gland before being secreted into the bloodstream. These are:

  • anti-diuretic hormone (also called vasopressin), which controls water balance and blood pressure
  • oxytocin, which stimulates uterine contractions during labour and milk secretion during breastfeeding.

Between the anterior pituitary and the posterior pituitary lies the intermediate pituitary gland. Cells here produce:

  • melanocyte-stimulating hormone, which acts on cells in the skin to stimulate the production of melanin.

What could go wrong with my pituitary gland?

The pituitary gland is an important gland in the body and the hormones it produces carry out varied tasks and regulate the function of many other organs. This means that the symptoms experienced when the pituitary gland stops working correctly can be different, depending on which hormone is affected.

Conditions that affect the pituitary gland directly can be divided into three main categories:

  1. Conditions that cause the pituitary gland to produce too much of one or more hormone(s). Examples include acromegaly, Cushing’s disease and prolactinoma.
  2. Conditions that cause the pituitary gland to produce too little of one or more hormone(s). Examples include adult-onset growth hormone deficiency, diabetes insipidus’ data-content=’1239′ >diabetes insipidus and hypopituitarism.
  3. Conditions that alter the size and/or shape of the pituitary gland. Examples include empty sella syndrome.

A cell type may divide and then form a small benign lump, known as a tumour, and the patient may then suffer from the effects of too much of the hormone the cell produces. If the tumour grows very large, even though still benign, it may squash the surrounding cells and stop them working (hypopituitarism), or push upwards and interfere with vision – a visual field defect. Very occasionally, the tumour may expand sideways and cause double vision as it affects the nerves that control eye movements. It should be emphasised that even when these tumours are large, they very rarely spread to other parts of the body.
