Yuzpe Regimen
The Yuzpe regimen is a method of emergency contraception that uses a combination of ethinyl estradiol and levonorgestrel. It is less effective and less commonly used than a larger dose of levonorgestrel alone, a dose of ulipristal acetate, or insertion of a copper intrauterine device. It is designed to be used within 72 hours of unprotected sexual intercourse because it works by inhibiting ovulation. Typically, the Yuzpe regimen uses several doses of combined oral contraceptive pills. It may be preferred in locations where other forms of emergency contraception are unavailable or accessing emergency contraception carries a societal stigma. In these places, people often self-administer combined oral contraceptives as emergency contraception. Subsequently, the World Health Organization (WHO) undertook an investigation into the use of progestogen-only tablets as an Emergency Hormonal Contraceptive (i.e. without any estrogen component). This showed greater efficacy with reduced side ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emergency Contraception
Emergency contraception (EC) is a birth control measure, used after sexual intercourse to prevent pregnancy. There are different forms of EC. Emergency contraceptive pills (ECPs), sometimes simply referred to as emergency contraceptives (ECs), or the morning-after pill, are medications intended to disrupt or delay ovulation or fertilization, which are necessary for pregnancy. p. 121: Intrauterine devices (IUDs)usually used as a primary contraceptive methodare sometimes used as the most effective form of emergency contraception. However, the use of IUDs for emergency contraception is relatively rare. Definition Emergency contraception is a birth control measure taken to reduce the risk of pregnancy following unprotected sexual intercourse or when other regular contraceptive measures have not worked properly or have not been used correctly. It is intended to be used occasionally and is not the same as medical abortion. Emergency contraception is offered to women who do not wish ...

Ethinyl Estradiol
Ethinylestradiol (EE) is an estrogen medication which is used widely in birth control pills in combination with progestins. In the past, EE was widely used for various indications such as the treatment of menopausal symptoms, gynecological disorders, and certain hormone-sensitive cancers. It is usually taken by mouth but is also used as a patch and vaginal ring. The general side effects of EE include breast tenderness and enlargement, headache, fluid retention, and nausea among others. In men, EE can additionally cause breast development, feminization in general, hypogonadism, and sexual dysfunction. Rare but serious side effects include blood clots, liver damage, and cancer of the uterus. EE is an estrogen, or an agonist of the estrogen receptors, the biological target of estrogens like estradiol. It is a synthetic derivative of estradiol, a natural estrogen, and differs from it in various ways. Compared to estradiol, EE has greatly improved bioavailability when tak ...

Levonorgestrel
Levonorgestrel is a hormonal medication which is used in a number of birth control methods. It is combined with an estrogen to make combination birth control pills. As an emergency birth control, sold under the brand name Plan B One-Step among others, it is useful within 72 hours of unprotected sex. The more time that has passed since sex, the less effective the medication becomes, and it does not work after pregnancy ( implantation) has occurred. Levonorgestrel works by preventing ovulation or fertilization from occurring. It decreases the chances of pregnancy by 57 to 93%. In an intrauterine device (IUD), such as Mirena among others, it is effective for the long-term prevention of pregnancy. A levonorgestrel-releasing implant is also available in some countries. Common side effects include nausea, breast tenderness, headaches, and increased, decreased, or irregular menstrual bleeding. When used as an emergency contraceptive, if pregnancy occurs, there is no evidence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ulipristal Acetate
Ulipristal acetate, sold under the brand name Ella among others, is a medication used for emergency contraception (birth control) and uterine fibroids. As emergency contraception it should be used within 120 hours of vaginally penetrating intercourse. For fibroids it may be taken for up to six months. It is taken by mouth. Common side effects include headache, nausea, feeling tired, and abdominal pain. It should not be used in women who are already pregnant. It is in the selective progesterone receptor modulator (SPRM) class of medications. It works by preventing the effects of progesterone, therefore preventing ovulation but not affecting fertilization or implantation. Ulipristal acetate was approved for medical use in the United States in 2010. It is on the World Health Organization's List of Essential Medicines. Medical uses Emergency contraception For emergency contraception a 30 mg tablet is used within 120 hours (5 days) after unprotected intercourse or c ...

Copper IUDs
Intrauterine device (IUD) with copper, also known as intrauterine coil or copper coil, is a type of intrauterine device which contains copper. It is used for birth control and emergency contraception within five days of unprotected sex. It is one of the most effective forms of birth control with a one-year failure rate around 0.7%. The device is placed in the uterus and lasts up to twelve years. It may be used by women of all ages regardless of whether or not they have had children. Following removal, fertility quickly returns. Side effects may be heavy menstrual periods, and/or rarely the device may come out. It is less recommended for people at high risk of sexually transmitted infections as it may increase the risk of pelvic inflammatory disease in the first three weeks after insertion. It is recommended for people who don't tolerate or hardly tolerate hormonal contraceptives. If a woman becomes pregnant with an IUD in place removal is recommended. Very rarely, uterine perfora ...

Combined Oral Contraceptive Pill
The combined oral contraceptive pill (COCP), often referred to as the birth control pill or colloquially as "the pill", is a type of birth control that is designed to be taken orally by women. The pill contains two important hormones: progestin (a synthetic form of the hormone progestogen/progesterone) and estrogen (usually ethinylestradiol and 17β estradiol). When taken correctly, it alters the menstrual cycle to eliminate ovulation and prevent pregnancy. COCPs were first approved for contraceptive use in the United States in 1960, and are a very popular form of birth control. They are used by more than 100 million women worldwide and by about 9 million women in the United States. From 2015 to 2017, 12.6% of women aged 15–49 in the US reported using COCPs, making it the second most common method of contraception in this age range (female sterilization is the most common method). Use of COCPs, however, varies widely by country, age, education, and marital status. For e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mifepristone
Mifepristone, also known as RU-486, is a medication typically used in combination with misoprostol to bring about a medical abortion during pregnancy and manage early miscarriage. This combination is 97% effective during the first 63 days of pregnancy. It is also effective in the second trimester of pregnancy. Effectiveness should be verified two weeks after use. It is taken by mouth. Common side effects include abdominal pain, feeling tired, and vaginal bleeding. Serious side effects may include heavy vaginal bleeding, bacterial infection, and birth defects if the pregnancy does not end. If used, appropriate follow up care needs to be available. Mifepristone is an antiprogestogen. It works by blocking the effects of progesterone, making both the cervix and uterine vessels dilate and causing uterine contraction. Mifepristone was developed in 1980 and came into use in France in 1987. It became available in the United States in 2000. It is on the World Health Organization's ...

Canadian
Canadians (french: Canadiens) are people identified with the country of Canada. This connection may be residential, legal, historical or cultural. For most Canadians, many (or all) of these connections exist and are collectively the source of their being ''Canadian''. Canada is a multilingual and multicultural society home to people of groups of many different ethnic, religious, and national origins, with the majority of the population made up of Old World immigrants and their descendants. Following the initial period of French and then the much larger British colonization, different waves (or peaks) of immigration and settlement of non-indigenous peoples took place over the course of nearly two centuries and continue today. Elements of Indigenous, French, British, and more recent immigrant customs, languages, and religions have combined to form the culture of Canada, and thus a Canadian identity. Canada has also been strongly influenced by its linguistic, geographic, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pregnancy From Rape
Pregnancy is a potential result of rape. It has been studied in the context of war, particularly as a tool for genocide, as well as other unrelated contexts, such as rape by a stranger, statutory rape, incest, and underage pregnancy. The current scientific consensus is that rape is at least as likely to lead to pregnancy as consensual sexual intercourse, with some studies suggesting rape may actually result in higher rates of pregnancy than consensual intercourse.Dellorto, Danielle (22 August 2012)"Experts: Rape does not lower odds of pregnancy" CNN Health.Begley, Sharon; Heavey, Susan (20 August 2012)"Rape trauma as barrier to pregnancy has no scientific basis" ReutersArchive version Rape can cause difficulties during and after pregnancy, with potential negative consequences for both the victim and a resulting child. Medical treatment following a rape includes testing for, preventing, and managing pregnancy. A woman who becomes pregnant after a rape may face a decision about ...
