Segesterone Acetate
Segesterone acetate (SGA), sold under the brand names Nestorone, Elcometrine, and Annovera, is a progestin medication which is used in birth control and in the treatment of endometriosis in the United States, Brazil, and other South American countries.https://www.accessdata.fda.gov/drugsatfda_docs/label/2018/209627s000lbl.pdf It is available both alone and in combination with an estrogen. It is not effective by mouth and must be given by other routes, most typically as a vaginal ring or implant that is placed into fat. Side effects of SGA are similar to those of other progestins. SGA is a progestin, or a synthetic progestogen, and hence is an agonist of the progesterone receptor, the biological target of progestogens like progesterone. It has some affinity for the glucocorticoid receptor and has no other important hormonal activity. SGA was developed by the Population Council and was introduced for medical use by 2000. It is under development in the United States and Europe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Contraceptive Vaginal Ring
A contraceptive vaginal ring is a type of hormonal insert that is placed in the vagina for the purpose of birth control. The rings themselves utilize a plastic polymer matrix that is inlaid or embedded with contraceptive drug. This drug, often one or two hormones, is absorbed directly through the bloodstream through the cells that line the vaginal wall. Some vaginal rings contain both an estrogen and a progestin (brand names NuvaRing and Annovera), which are available in Europe and the United States. Other vaginal rings contain just progesterone (brand name Progering). The progesterone-only ring is only available in Latin America, exclusively for postpartum breastfeeding parents, therefore, it is not available in the United States. The Progering is made of silicone-elastorone with an outer diameter of 58 mm and cross-sectional diameter of 8.4 mm. Similarly, Annovera has an outer diameter of 56 mm and cross-sectional diameter of 8.4 mm. In contrast, the Nuvaring has a diameter of ...

Population Council
The Population Council is an international, nonprofit, non-governmental organization. The Council conducts research in biomedicine, social science, and public health and helps build research capacities in developing countries. One-third of its research relates to HIV and AIDS; while its other major program areas are in reproductive health and its relation to poverty, youth, and gender. For example, the Population Council strives to teach boys that they can be involved in contraceptive methods regardless of stereotypes that limit male responsibility in child bearing. The organization held the license for Norplant contraceptive implant, and now holds the license for Mirena intrauterine system. The Population Council also publishes the journal ''Population and Development Review'', which reports scientific research on the interrelationships between population and socioeconomic development. It also provides a forum for discussion on related issues of public policy and '' Studies in Fami ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Combined Hormonal Birth Control
Combined hormonal contraception (CHC), or combined birth control, is a form of hormonal contraception which combines both an estrogen and a progestogen in varying formulations. The different types available include the pill, the patch and the vaginal ring, which are all widely available, and an injection, which is available in only some countries. They work by mainly suppressing luteinising hormone (LH) and follicle-stimulating hormone (FSH) and in turn preventing ovulation. The pill, patch, and vaginal ring are all about 93% effective with typical use. Beneficial health effects include reduced risks of ovarian, endometrial and colorectal cancers. CHC can also provide improved control of some menstrual problems. Adverse effects include a small but higher risk of venous thromboembolism, arterial thromboembolism, breast cancer and cervical cancer. Medical use Contraceptive use With perfect use, less than 1% of women will become pregnant during the first year of using CHC. Howeve ...

Vaginal Bleeding
Vaginal bleeding is any expulsion of blood from the vagina. This bleeding may originate from the uterus, vaginal wall, or cervix. Generally, it is either part of a normal menstrual cycle or is caused by hormonal or other problems of the reproductive system, such as abnormal uterine bleeding. Vaginal bleeding during pregnancy can be normal, especially in early pregnancy. However, bleeding may also indicate a pregnancy complication that needs to be medically addressed. During pregnancy bleeding is usually, but not always, related to the pregnancy itself. Regular monthly vaginal bleeding during the reproductive years, menstruation, is a normal physiologic process. During the reproductive years, bleeding that is excessively heavy (menorrhagia or heavy menstrual bleeding), occurs between monthly menstrual periods (intermenstrual bleeding), occurs more frequently than every 21 days (abnormal uterine bleeding), occurs too infrequently (oligomenorrhea), or occurs after vaginal intercours ...

Combined Injectable Birth Control
Combined injectable contraceptives (CICs) are a form of hormonal birth control for women. They consist of monthly injections of combined formulations containing an estrogen and a progestin to prevent pregnancy. CICs are different from progestogen-only injectable contraceptives (POICs), such as depot medroxyprogesterone acetate (DMPA; brand names Depo-Provera, Depo-SubQ Provera 104) and norethisterone enantate (NETE; brand name Noristerat), which are not combined with an estrogen and are given once every two to three months instead of once a month. Hormonal contraception works primarily by preventing ovulation, but it may also thicken the cervical mucus inhibiting sperm penetration. Hormonal contraceptives also have effects on the endometrium, that theoretically could affect implantation. Medical uses CICs are administered by intramuscular injection into the deltoid, gluteus maximus, or anterior thigh. They are ideally administered every 28 to 30 days, though they ha ...

NuvaRing
Ethinylestradiol/etonogestrel, sold under the brand names NuvaRing among others, is a hormonal vaginal ring used for birth control and to improve menstrual symptoms. It contains ethinylestradiol, an estrogen, and etonogestrel, a progestin. It is used by insertion into the vagina. Pregnancy occurs in about 0.3% of women with perfect use and 9% of women with typical use. Table 26–1 = Common side effects include irregular vaginal bleeding, nausea, sore breasts, vaginitis, mood changes, and headache. Rare but serious side effects may include blood clots, toxic shock syndrome, anaphylaxis, gallstones, and liver problems. Use is not recommended in those who both smoke and are over the age of 35. While use in pregnancy is not recommended, such use has not been found to be harmful to the baby. Use during breastfeeding is typically not recommended as it may decrease the milk supply. It mainly works by decreasing gonadotropins thereby stopping ovulation. The combination was ap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ethinylestradiol
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 taken by m ...
