Axis Powers
The Axis powers, originally called the Rome–Berlin Axis and also Rome–Berlin–Tokyo Axis, was the military coalition which initiated World War II and fought against the Allies of World War II, Allies. Its principal members were Nazi Germany, Fascist Italy, Kingdom of Italy and the Empire of Japan. The Axis were united in their far-right positions and general opposition to the Allies, but otherwise lacked comparable coordination and ideological cohesion. The Axis grew out of successive diplomatic efforts by Germany, Italy, and Japan to secure their own specific expansionist interests in the mid-1930s. The first step was the Italo-German protocol of 23 October 1936, protocol signed by Germany and Italy in October 1936, after which Italian leader Benito Mussolini declared that all other European countries would thereafter rotate on the Rome–Berlin axis, thus creating the term "Axis". The following November saw the ratification of the Anti-Comintern Pact, an anti-communis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The uterus (from Latin ''uterus'', : uteri or uteruses) or womb () is the hollow organ, organ in the reproductive system of most female mammals, including humans, that accommodates the embryonic development, embryonic and prenatal development, fetal development of one or more Fertilized egg, fertilized eggs until birth. The uterus is a hormone-responsive sex organ that contains uterine gland, glands in its endometrium, lining that secrete uterine milk for embryonic nourishment. (The term ''uterus'' is also applied to analogous structures in some non-mammalian animals.) In humans, the lower end of the uterus is a narrow part known as the Uterine isthmus, isthmus that connects to the cervix, the anterior gateway leading to the vagina. The upper end, the body of the uterus, is connected to the fallopian tubes at the uterine horns; the rounded part, the fundus, is above the openings to the fallopian tubes. The connection of the uterine cavity with a fallopian tube is called the utero ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gold
Gold is a chemical element; it has chemical symbol Au (from Latin ) and atomic number 79. In its pure form, it is a brightness, bright, slightly orange-yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal, a group 11 element, and one of the noble metals. It is one of the least reactivity (chemistry), reactive chemical elements, being the second-lowest in the reactivity series. It is solid under standard temperature and pressure, standard conditions. Gold often occurs in free elemental (native state (metallurgy), native state), as gold nugget, nuggets or grains, in rock (geology), rocks, vein (geology), veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as in electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ernst Gräfenberg
Ernst Gräfenberg (26 September 1881 – 28 October 1957) was a German-born physician and scientist. He developed the intrauterine device (IUD), and studied the role of the woman's urethra in orgasm. The G-spot is named after him. Career Gräfenberg studied medicine in Göttingen and Munich, earning his doctorate on 10 March 1905. He began working as a doctor of ophthalmology at the university of Würzburg, but then moved to the Department of Obstetrics and Gynaecology at the University of Kiel, where he published papers on cancer metastasis (the "Gräfenberg theory"), and the physiology of egg implantation. In 1910 Gräfenberg worked as a gynaecologist in Berlin, and by 1920 was quite successful, with an office on the Kurfürstendamm. He was chief gynaecologist of a municipal hospital in Britz, a working-class Berlin district, and was beginning scientific studies of the physiology of human reproduction at Berlin University.

Gräfenberg's Ring
Gräfenberg's ring is a flexible ring of silk suture, later versions of which were wrapped in silver wire. It was an early IUD, a birth control device. Gräfenberg's ring was the first IUD used by a significant number of women. The ring was introduced by German gynecologist Ernst Gräfenberg in 1929. It ceased to be in wide use circa 1939. Inserting a foreign device into the uterus causes an inflammatory response, which creates a hostile environment for sperm. The silver wire used to construct later versions of Gräfenberg's ring was contaminated with copper, which increases this spermicidal effect. In 1934, Japanese physician Tenrei Ōta developed a variation of the Gräfenberg ring that contained a supportive structure in the center. The addition of this central disc lowered the IUD's expulsion rate. However, insertion of these devices caused high rates of infection and were condemned by the medical community. Furthermore, their use and development was stifled by World Wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birth Control In Japan
Birth control in Japan has been available since at least the 17th century, and its evolution has been informed by political, social, and economic contexts. Prior to World War I common forms of birth control included abortion, infanticide, and condoms. Birth control as an oral contraceptive, while known in intellectual circles, was not widely circulated until the interwar period when the debate over birth control gained public support and momentum. However, it was the militarists, whose goal of achieving a strong population in order to establish Japan as an international power prevailed, as Japan prepared to enter World War II. The end of World War II, and Japan's subsequent demilitarization brought an emphasis on population reduction by the US-led occupation SCAP ( Supreme Command for the Allied Powers) who were fearful of a rise in communism or militarism which would create a threat to democracy and the "free-world." Today various types of birth control in Japan are available to w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
