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. A doctor may recommend a … [Read more...] about What happens during a testicular ultrasound?

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. According to the Department of Health and Human Services, USA, approximately 10% to 15% of couples in the USA are infertile - meaning … [Read more...] about Infertility: Causes, Diagnosis, Risks, Treatments
As children approach their early teens, puberty begins. These are the changes that will lead to adulthood, and the ability to have children. The developments affect the body in terms of size, shape, and composition, as well as internal body systems and structure. Psychological and social changes also take place. Boys and girls grow rapidly in the first half of puberty, and they stop growing when puberty is completed. Hormone signals from the brain will tell the body that it is time for puberty to start. The signals will go to the ovaries in females, and the testes in males. In response, the ovaries and testes produce a range of hormones that stimulate growth and change in various parts of the body, including the reproductive organs, breasts, skin, muscles, bones, hair, and the brain. Puberty differs in a number of ways between boys and girls. Girls start puberty about 1 to 2 years earlier than boys, and they generally finish more quickly. Girls reach adult height and are … [Read more...] about Puberty in boys and girls: What is it all about?

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?
An undescended testicle is a testicle that has not moved into the scrotum, the bag of skin that hangs behind the penis, before a baby is born. It is estimated that 3 percent to 4 percent of full-term boys and 21 percent of male infants born preterm are born with this feature. Usually, only one testicle is affected, but 10 percent of all cases, both testicles are affected. Undescended testicle (UDT) is also known as cryptorchidism. It is one of the most common endocrine problems affecting newborn males, and it is the most common genital condition that is identified at birth. It is more likely to affect boys who are born prematurely. Whether it affects one or both testicles, cryptorchidism generally corrects itself within a few months, but sometimes surgery is needed to relocate the testicle, or testis, into the scrotum. The scrotum is a small pouch, or sac, of skin that hangs behind the penis. Inside the scrotum is a pair of testicles, the oval-shaped sex organs that form … [Read more...] about What is Cryptorchidism, or Undescended Testicle?
The spermatic cord provides blood flow to the testicle. When a testicle rotates on this cord, it is referred to as testicular torsion; it causes the flow of blood to stop, causing sudden, often severe pain, and swelling. Prolonged testicular torsion and loss of blood flow can lead to the death of the testicle and surrounding tissues. Testicular torsion is serious but treatable. Each testicle is attached to the spermatic cord and the scrotum. Testicular torsion happens if the testicle rotates on the cord that runs upward from the testicle into the abdomen. The rotation twists the spermatic cord and reduces blood flow. If the testicle rotates several times, blood flow can be entirely blocked, causing damage more quickly. Males who experience testicular torsion may have an inherited trait that allows one or both testicles to rotate freely inside the scrotum. The testicle is only attached to the spermatic cord, and not to the scrotum. This is called a "bell clapper scrotum," … [Read more...] about Testicular torsion: Causes, symptoms, and treatment
