IV. Intrauterine devices: The Intrauterine Device (IUD) is the most commonly utilized reversible contraceptive method in the world. Types of IUDs: 1- Unmedicated IUDs: The IUDs have lippes Loop, made of plastic (polyethylene) impregnated with barium sulfate. They are still utilized allover the world except in the United States. Flexible stainless steel rings are utilized widely only in China and not elsewhere. The other unmedicated devices are condemned as they cause side effects such as Pelvic Inflammatory

teen pregnancies and lower abortion rates. Birth control also help women who struggle with certain health issues to not get pregnant sence a prgnacy put strain in the mother and child. Birth control works by releasing the hormones estrogen and progesterone to prevent ovulation, it very effective if taken correctly everyday at nearly the same time each day. Birth control is not 100% effective because each year 9 out of 100 women may get pregnant if they rely on birth control alone. “If pills are

Theres no question that today's young athletes feel enormous pressure to be faster, stronger and better-- all the time. And it’s part of the reason why young teens are turning to steroids,” says Michael Maloney M.D. reporting to University of Rochester Medical Center. Today many people in the world are turning to steroids to enhance physical features. What they don't know is that steroids can actually effect your body negatively in the future. Many of these effects can be physically unattractive

Each process, which takes place in the human body, should be regulated. The two systems, which perform regulation, are the nervous system and the endocrine system. The nervous system is concerned with fast responses to certain environmental or internal stimuli. In contrast, the endocrine system is responsible of the slower control mechanisms, which address the long-term processes, such as circadian rhythms and growth. The endocrine organs are capable of production of messengers, or hormones, which

signaling, reduction of angiogenesis and decreased DNA repair. This drug is approved by the U.S. Food and Drug Administration as first-line therapy in combination with another drug or as monotherapy in patients who node negative (estrogen receptor– or progesterone receptor–negative or with one high-risk feature) and who had previously received cancer therapy for their metastatic disease. Trastuzumab is also indicated for the treatment of HER2-positive breast cancer in the adjuvant setting because it is shown

carry out one function. When it comes to conception; progesterone, the pregnancy hormone, is vital to becoming pregnant. This hormone works to get the uterus to the point where it can maintain a zygote, or fertilized egg. How are these related? Progesterone is used to make cortisol. If your body is constantly trying to produce a sufficient amount of cortisol to lower your adrenaline from too much stress then that will leave little or no progesterone left to conceive. This is also a factor in why women

Traumatic brain injury (TBI) affects 1.7 million people annually in the U.S. with 275,000 hospitalizations and 52,000 deaths. In 2010, the medical cost for treating TBI patients in the U.S. was $76.5 billion and rising annually. Primary causes for TBI include the following: motor vehicle crashes, falls, assaults and sports or recreation-related injuries (concussions). Finding the right treatment to reduce mortality rates and improve the clinical outcomes in TBI patients has been elusive. Professor

Southern White Rhinoceroses (Ceratotherium simum simum), Moesha (#1357) and Kito (#1353) at Hamilton Zoo were investigated and analysed by non-invasive faecal progesterone concentrations. These two females have had limited reproductive success with one in a long period of acyclicity and the other with normal cycles. Monitoring progesterone levels allows the zoo keepers at Hamilton Zoo to be able to introduce the male Kruger (#1273) when the females are in oestrous (especially if no reproductive behaviour

The first pregnancy that resulted from AI was accounted for in 1998 using fresh semen and was done by detecting a slight rise in progesterone prior to ovulation, indicating proper timing for insemination.9, 14 Now ultrasonagraphy can also be used to detect imminent ovulation as follicular development is easily followed, as well as detect the timing of ovulation.14 It is common for the
