A testicular ultrasound is a low-risk procedure that is used to diagnose a range of medical issues, such as testicular torsion, testicular cancer, and epididymitis. This article will look at the uses of testicular ultrasound, what to expect during the procedure, and how to prepare for a scan. An ultrasound is a medical procedure that uses sound waves to create a picture of the inside of the body. The images can help a doctor to diagnose an illness or injury. A testicular ultrasound, also called ultrasound imaging of the scrotum, looks specifically at the testicles. The testicles are part of the male reproductive system. Their primary purpose is to create sperm and hormones. Testicles are contained within a sac called the scrotum. The ultrasound procedure is safe, very low-risk, and non-invasive. The examination takes place entirely outside the body. A testicular ultrasound is used to investigate a range of problems with the scrotum, testicles, or epididymis.

Your 20s are when you're in your physical prime. Consider the average ages of all-stars in major sports: 25 (hockey), 27 (basketball), 28 (football), and 29 (baseball). Peak levels of testosterone and growth hormone course through your body, making it easier to build muscle. And your metabolic furnace burns at max levels, vaporizing calories. But it's not just your body that's emboldened. "Your brain is at the peak of its development in fluid intelligence—the speed of responding to new information," says Jeffrey Jensen Arnett, Ph.D., a professor of psychology at Clark University. It's no accident that Steve Jobs was 21 when he cofounded Apple, and Bill Gates was 20 when he started Microsoft. Take the time to make small investments now to reap huge rewards later.Taking a calculated risk, like say, accepting a promotion that sends you out of the country for two years, can pay off. The key here is calculated. "Before making a risky decision, create lists of what you could gain and … [Read more...] about Live Great in Your 20s
MAINTENANCEYour privates are the result of centuries of engineering. Before leaving the factory, every effort was made to assure they were in good working condition. To keep them running smoothly, regular maintenance is required. To be done daily: It’s especially important for uncircumcised men to retract the foreskin and wash around the head of the penis every day. Otherwise, yeast infections and other problems may develop. Circumcised men should scrub regularly as well. To be done weekly (at least): Sex is the best exercise for your privates. Regularly flushing the system with nourishing blood and oxygen assures optimum sperm production, prostate health, and overall good performance.

It should be smooth and oval-shaped, feeling kind of like … [Read more...] about Checking Under the Hood
Infertility refers to an inability to conceive after having regular unprotected sex. Infertility can also refer to the biological inability of an individual to contribute to conception, or to a female who cannot carry a pregnancy to full term. In many countries infertility refers to a couple that has failed to conceive after 12 months of regular sexual intercourse without the use of contraception. Studies indicate that slightly over half of all cases of infertility are a result of female conditions, while the rest are caused by either sperm disorders or unidentified factors. According to The Mayo Clinic, USA: About 20% of cases of infertility are due to a problem in the man. About 40% to 50% of cases of infertility are due to a problem in the woman. About 30% to 40% of cases of infertility are due to problems in both the man and the woman.

Stomach cancer, also known as gastric cancer, is the accumulation of an abnormal (malignant, cancerous) group of cells that form a mass in a part of the stomach. According to the World Health Organization, 723,000 cancer-related deaths are caused by stomach cancer each year, globally. It is the fifth most common cancer worldwide, but the third leading cause of cancer-related deaths. In the United States, there are approximately 25,500 new cases of stomach cancer, annually - it represents 2 percent of all new cancers diagnosed in the country. The majority of people diagnosed with stomach cancer either already have metastasis or eventually develop it. Metastasis is when the cancer spreads from the area where it first developed. Around 90-95 percent of all stomach cancers are a type referred to as adenocarcinoma of the stomach. In this version, the cancer develops from the cells that form the mucosa, the most superficial lining of the stomach that produces mucus. There are … [Read more...] about Stomach Cancer: Causes, Symptoms, and Treatments
In vitro fertilization (IVF) is the most common and most effective type of assisted reproductive technology (ART) to help women become pregnant. The IVF procedure involves fertilizing an egg outside the body, in a laboratory dish, and then implanting it in a woman's uterus. In a normal pregnancy a male sperm penetrates a woman's egg and fertilizes it inside her body after ovulation - when a mature egg has been released from the ovaries. The fertilized egg (now an embryo) then attaches itself to the wall of the uterus (womb) and begins developing into a baby. This is known as natural conception. However, some women are unable to become pregnant through natural or unassisted conception and have to undergo fertility treatment to become pregnant. If less expensive fertility techniques do not work, some women may decide to opt for IVF. According to the American Society for Reproductive Medicine, about 1% of U.S. infants are conceived through IVF. To date, IVF has contributed to … [Read more...] about IVF: What Are Test Tube Babies?
An ultrasound scan uses high-frequency sound waves to create images of the inside of the body. It is suitable for use during pregnancy. Ultrasound scans, or sonography, are safe because they use sound waves or echoes to make an image, instead of radiation. Ultrasound scans are used to evaluate fetal development, and they can detect problems in the liver, heart, kidney, or abdomen. They may also assist in performing certain types of biopsy. The image produced is called a sonogram. The person who performs an ultrasound scan is called a sonographer, but the images are interpreted by radiologists, cardiologists, or other specialists. The sonographer usually holds a transducer, a hand-held device, like a wand, which is placed on the patient's skin. Ultrasound is sound that travels through soft tissue and fluids, but it bounces back, or echoes, off denser surfaces. This is how it creates an image. The term "ultrasound" refers to sound with a frequency that humans cannot hear. For … [Read more...] about Ultrasound scans: How do they work?
Varicoceles are similar to varicose veins, but they occur around the testicles rather than the legs. They do not usually cause any serious problems, but they can impact male fertility. They happen when certain veins in the scrotum become enlarged, due to a malfunction in some of the valves involved in pumping the blood. They affect around 15 percent of males, and they tend to form between the ages of 15 and 25 years. Varicoceles normally affect just one side, usually the left. This article will look at the causes, symptoms and treatments of varicoceles. A varicocele is an enlargement of the veins in the scrotum, the the bag that contains the testes. They are similar to varicose veins of the leg. They affect a type of vein known as the pampiniform plexus. The pampiniform plexus is found in the spermatic cord. This cord also holds the vas deferens, the tube that carries sperm, and the testicular artery, which transports blood to the testicles. The creation of sperm is most efficient at … [Read more...] about What is a varicocele and should I worry about it?
