Intrauterine devices (IUDs) should be used routinely to provide emergency contraception, according to the authors of the first systematic review of all available data from the past 35 years. They found that IUDs had a failure rate of less than one per thousand and were a more effective form of emergency contraception than the "morning after pill". In addition, IUDs continued to protect women from unwanted pregnancy for many more years if they were left in place. http://medicalxpress.com/news/2012-05-intrauterine-devices-effective-emergency-contraception.html Obstetrics & gynaecology Tue, 08 May 2012 19:00:01 EST news255712156 American and Spanish researchers have found potential ways for doctors to improve the treatment of hormone receptor-positive breast cancer even if they lack access to costly multi-gene tests, as they report at the 4th IMPAKT Breast Cancer Conference. http://medicalxpress.com/news/2012-05-progesterone-receptor-hormone-receptor-positive-cancer.html Cancer Thu, 03 May 2012 11:30:03 EST news255261199 Researchers at the University of Cincinnati (UC) have found that intrauterine devices (IUDs) containing progesterone are a safe and effective means of birth control and support its use as a treatment option for medical conditions like pelvic pain, abnormal bleeding, and to prevent uterine cancer. http://medicalxpress.com/news/2012-04-iuds-contraception-conditions.html Obstetrics & gynaecology Fri, 13 Apr 2012 06:40:53 EST news253518041 (HealthDay) -- U.S. health officials announced Tuesday that birth controls pills containing drospirenone -- a man-made version of the hormone progesterone -- may be associated with a higher risk of blood clots and will require new labels. http://medicalxpress.com/news/2012-04-birth-pills-higher-blood-clot.html Medications Tue, 10 Apr 2012 16:47:51 EST news253295261 An international team of scientists, including four at Simon Fraser University, has made a discovery that will change the way the most deadly form of breast cancer is treated. http://medicalxpress.com/news/2012-04-uncover-multiple-deadly-breast-cancer.html Cancer Wed, 04 Apr 2012 13:00:18 EST news252759374 Studies exploring the relationship between soy consumption and breast cancer have been mixed, but new research introduces a new thought: Could women with breast cancer who began eating soy as an adult develop a tumor more resistant to treatment? http://medicalxpress.com/news/2012-04-links-breast-cancer-resistance-soy.html Cancer Mon, 02 Apr 2012 14:00:01 EST news252584540 In a landmark study, researchers have linked the long-term use of estrogen plus progesterone and estrogen-only hormone therapy with a higher risk for developing breast cancer. http://medicalxpress.com/news/2012-04-long-term-estrogen-hormone-therapy-linked.html Cancer Mon, 02 Apr 2012 07:48:48 EST news252571721 Could blocking a testosterone receptor lead to a new way to treat an aggressive form of breast cancer?

Vaginal progesterone decreased the rate of preterm birth by 42%, and significantly reduced the rate of respiratory distress syndrome and the need for mechanical ventilation, as well as a composite of several complications of premature newborns (e.g. infection, necrotizing enterocolitis, intracranial hemorrhage, etc.).
