The removal of the ovaries together with the Fallopian tubes is called salpingo-oophorectomy. Oophorectomy and salpingo-oophorectomy are not common forms of birth control in humans; more usual is tubal ligation, in which the Fallopian tubes are blocked but the ovaries remain intact.
In humans, oophorectomy is most usually performed together with a hysterectomy - the removal of the uterus. Its use in a hysterectomy when there are no other health problems is somewhat controversial.
In animals, spaying involves an invasive removal of the ovaries, but rarely has major complications; the superstition that it causes weight gain is not based on fact. Spaying is especially important for certain animals that require the ovum to be released at a certain interval (called estrus or "heat"), such as cats and dogs. If the cell is not released during these animal's heat, it can cause severe medical problems that can be averted by spaying or partnering the animal with a male.
The Aegean Sea (Greek: Αιγαίον Πέλαγος, Aigaion Pelagos; Turkish: Ege denizi) is an arm of the Mediterranean Sea, located between the Greek peninsula and Anatolia (Asia Minor, now part of Turkey). It is connected to the Marmara Sea and Black Sea by the Dardanelles and Bosporus.
In ancient times the sea was the birthplace of two ancient civilizations - the Minoans of Crete, and Mycenean Civilization of the Peloponnese. Later arose the city-states of Athens, Sparta among many others that constituted the Hellenic Civilization. The Aegean Sea was later inhabited by Persians, Romans, the Byzantine Empire, the Venetians, the Seljuk Turks, and the Ottoman Empire. The Aegean was the site of the original democracies, and it allowed for contact between several diverse civilizations of the Eastern Mediterranean.
The Aegean islands can be simply divided into seven groups: the Thracian Sea group, the East Aegean group, the Northern Sporades, the Cyclades, the Saronic Islands (or, Argo-Saronic Islands), the Dodecanese and Crete. The word archipelago was originally applied specifically to these islands. Many of the Aegean islands, or chains of islands, are actually extensions of the mountains on the mainland. One chain extends across the sea to Chios, another extends across Euboea to Samos, and a third extends across the Peloponnese and Crete to Rhodes, dividing the Aegean from the Mediterranean. Many of the islands have safe harbours and bays, but navigation through the sea is generally difficult. Many of the islands are volcanic, and marble and iron are mined on other islands. The larger islands have some fertile valleys and plains.
In ancient times there were various explanations for the name "Aegean." It was said to have been named after the town of Aegae; Aegea, a queen of the Amazons who died in the sea; and Aegeus, the father of Theseus, who drowned himself in the sea when he thought his son had died.
