A female condom (also known as a femidom) is a device that is used during sexual intercourse as a barrier contraceptive to reduce the risk of sexually transmitted infections (STIs—such as gonorrhea, syphilis, and HIV, though its protection against them is inferior to that by male condoms) and unintended pregnancy. Invented by Danish MD Lasse Hessel, it is worn internally by the female partner and provides a physical barrier to prevent exposure to ejaculated semen or other body fluids. Female condoms can be used by the receptive partner during anal sex.〔(http://www.aidsmap.com/en/docs/A85BA23D-6F72-4CD2-90A4-D914A60BEF79.asp -->http://www.aidsmap.com/Female-condoms-for-anal-sex/page/1746303/ Female condoms for anal sex ) (archive 20090430 )〕〔(【引用サイトリンク】title=How to Put on a Female Condom (For Anal Sex) )〕 The female condom is a thin, soft, loose-fitting sheath with a flexible ring at each end. They typically come in various sizes. For most vaginas, a moderately sized condom is adequate; women who have recently given birth should try a large size first. The inner ring at the closed end of the sheath is used to insert the condom inside the vagina and to hold it in place during intercourse. The rolled outer ring at the open end of the sheath remains outside the vagina and covers part of the external genitalia. ==Versions and materials== The FC1 female condom was first made from polyurethane. The second generation female condom is called the FC2 and is made from synthetic nitrile.〔(【引用サイトリンク】title=Product )〕 (this material change was announced in September 2005,〔(PDF)〕 and full transition of the product line to FC2 was done by October 2009 〔(【引用サイトリンク】publisher=Female Health Company )〕). The newer nitrile condoms are less likely to make potentially distracting crinkling noises. FC2 was developed to take the place of FC1, providing the same safety and efficacy during use, but at a lower cost. It is hoped the nitrile condoms will also allow for significant reductions in female condom pricing.〔 FC2 is manufactured by The Female Health Company. The World Health Organization (WHO) has cleared FC2 for purchase by U.N. agencies and the UNFPA (a U.N. agency) has incorporated the female condom into national programming.〔(【引用サイトリンク】title=UNFPA )〕 They are sold under many brand names, including ''Reality, Femidom, Dominique, Femy, Myfemy, Protectiv'' and ''Care''. A recent version of the female condom is made from natural latex, the same material used in male condoms. This condom does not make the noises some experience with plastic condoms. This type of female condom is manufactured by Medtech Products Ltd, India. It is sold under various brand names, including ''Reddy'', ''V Amour'', ''L'amour'', ''VA WOW Feminine condom'', and ''Sutra''. One more clinical trial is required before it can be considered for FDA approval in the United States. The global health nonprofit Program for Appropriate Technology in Health (PATH) has also developed a female condom tailored for use in developing countries. The Woman's Condom is manufactured by Shanghai Dahua Medical Apparatus in China and is in early introduction.〔(【引用サイトリンク】title=PATH's woman's condom )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「female condom」の詳細全文を読む スポンサード リンク
