posterior lobe
in vertebrate anatomy, the pituitary gland, or hypophysis, is an endocrine gland about the size of a pea and weighing in humans. it is a protrusion off the bottom of the hypothalamus at the base of the brain. the hypophysis rests upon the hypophysial fossa of the sphenoid bone in the center of the middle cranial fossa and is surrounded by a small bony cavity (sella turcica) covered by a dural fold (diaphragma sellae). the anterior pituitary (or adenohypophysis) is a lobe of the gland that regulates several physiological processes (including stress, growth, reproduction, and lactation). the intermediate lobe synthesizes and secretes melanocyte-stimulating hormone. the posterior pituitary (or neurohypophysis) is a lobe of the gland that is functionally connected to the hypothalamus by the median eminence via a small tube called the pituitary stalk (also called the infundibular stalk or the infundibulum).

this is the most common cause of anovulation and is thought to account for about 70% of all cases. about half the women with hormonal imbalances do not produce enough follicles to ensure the development of an ovule, possibly due to poor hormonal secretions from the pituitary gland or the hypothalamus. the pituitary gland controls most other hormonal glands in the human body. therefore, any pituitary malfunctioning affects other glands under its influence, including the ovaries. this occurs in around 10% of cases. the mammary glands are also controlled by the pituitary gland, so lactation can also be affected. the pituitary gland is controlled by the hypothalamus. in 10% of cases, alterations in the chemical signals from the hypothalamus can easily seriously affect the ovaries.
