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.

Female Ejaculation
Female ejaculation is characterized as an expulsion of fluid from the Skene's gland at the lower end of the urethra during or before an orgasm. It is also known colloquially as squirting or gushing, although research indicates that female ejaculation and squirting are different phenomena, squirting being attributed to a sudden expulsion of liquid that partly comes from the bladder and contains urine. Female ejaculation is physiologically distinct from coital incontinence, with which it is sometimes confused. There have been few studies on female ejaculation. A failure to adopt common definitions and research methodology by the scientific community has been the primary contributor to this lack of experimental data. Research has suffered from highly selected participants, narrow case studies, or very small sample sizes, and consequently has yet to produce significant results. Much of the research into the composition of the fluid focuses on determining whether it is, or contains ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regnier De Graaf
Regnier de Graaf (English spelling), original Dutch spelling Reinier de Graaf, or Latinized Reijnerus de Graeff (30 July 164117 August 1673), was a Dutch physician, physiologist and anatomy, anatomist who made key discoveries in reproductive biology. He specialized in iatrochemistry and iatrogenesis, and was the first to develop a syringe to inject dye into human reproductive organs so that he could understand their structure and function. Biography De Graaf was born in Schoonhoven in a Roman Catholic family, as the son of a carpenter/engineer (equivalent to a modern architect). He studied medicine in Leuven (1658), Utrecht and Leiden (1663). There his co-students were Jan Swammerdam, Niels Stensen, Ole Borch and Frederik Ruysch, cooperating with professor Franciscus Sylvius, Johannes van Horne and :de:Lucas Schacht, Lucas Schacht. All of them were interested in the organs of procreation and influenced by Rene Descartes' Iatrophysics, iatrophysical approach. He submitted his ...

Intrauterine Device
An intrauterine device (IUD), also known as an intrauterine contraceptive device (IUCD or ICD) or coil, is a small, often T-shaped birth control device that is inserted into the uterus to prevent pregnancy. IUDs are a form of long-acting reversible contraception (LARC). The use of IUDs as a form of birth control dates from the 1800s. A previous model known as the Dalkon shield was associated with an increased risk of pelvic inflammatory disease (PID). However, current models do not affect PID risk in women without sexually transmitted infections during the time of insertion. Although copper IUDs may increase menstrual bleeding and result in painful cramps, hormonal IUDs may reduce menstrual bleeding or stop menstruation altogether. However, women can have daily spotting for several months after insertion, and it can take up to three months for there to be a 90% decrease in bleeding with hormonal IUDs. Cramping can be treated with NSAIDs. More serious potential complications ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
