Detailed examination of the joints is usually not included in the routine medical examination. However, joint related complaints are rather common, and understanding anatomy and physiology of both normal function and pathologic conditions is critically important when evaluating the symptomatic patient. By gaining an appreciation for the basic structures and functioning of the joint, you'll be able to "logic" your way thru the exam, even if you can't remember the eponym attached to each specific test!
A penile prosthesis is another treatment option for men with erectile dysfunction. These devices are either malleable (bendable) or inflatable. The simplest type of prosthesis consists of a pair of malleable rods surgically implanted within the erection chambers of the penis. With this type of implant the penis is always semi-rigid and merely needs to be lifted or adjusted into the erect position to initiate sex. This type of implant is a good choice for men with spinal cord injuries and/or limited hand strength. Today, many men choose a hydraulic, inflatable prosthesis, which allows them to have an erection when they choose, and it's easier to conceal. It is also more natural. A penile implant is usually used when there is a clear medical cause for ED and when the problem is unlikely to resolve or improve naturally or with other medical treatments. Sometimes a penile prosthesis is implanted during surgery to reconstruct the penis when scarring has caused erections to curve (Peyronie's disease). Penile implant surgeries take about an hour and are typically done in an outpatient center. A man can resume sexual intercourse by 6 weeks after surgery.
To use the diaphragm, first cover the inside of it with spermicide. Then insert it into your vagina so that it covers your cervix. You can insert the diaphragm up to 6 hours before sex. You should leave it in for at least 6 hours after the last time you have sex.
An undescended testicle (cryptorchidism) is a testicle that hasn't moved into its proper position in the bag of skin hanging below the penis (scrotum) before birth. Usually just one testicle is affected, but about 10 percent of the time both testicles are undescended. An undescended testicle is uncommon in general, but common among baby boys born prematurely. The vast majority of the time, the undescended testicle moves into the proper position on its own, within the first few months of life. If your son has an undescended testicle that doesn't correct itself, surgery can relocate the testicle into the scrotum.
Dr. Jeffrey Ojemann, director of epilepsy surgery at Seattle Children's Hospital, explains a cutting-edge treatment for epilepsy: minimally invasive MRI-guided laser ablation surgery. Laser ablation surgery is much safer and more precise than other treatments, with fewer side effects.

Morning erections have colloquially been termed as “morning wood” while scientifically it is called nocturnal penile tumescence. It is a normal and healthy physiological reaction and response that most men experience in their lives. Morning erections are really the ending of a series of erections that happen to men during the night. Healthy men can, on average, have anywhere between three to five erections in a full night of sleep, each of which lasts from 25-35 minutes.
An abdominal aortic aneurysm is an enlarged area in the lower part of the aorta, the major blood vessel that supplies blood to the body. The aorta, about the thickness of a garden hose, runs from your heart through the center of your chest and abdomen. Because the aorta is the body's main supplier of blood, a ruptured abdominal aortic aneurysm can cause life-threatening bleeding. Depending on the size and the rate at which your abdominal aortic aneurysm is growing, treatment may vary from watchful waiting to emergency surgery. Once an abdominal aortic aneurysm is found, doctors will closely monitor it so that surgery can be planned if it's necessary. Emergency surgery for a ruptured abdominal aortic aneurysm can be risky.
There are lots of fallacies about the missionary position being the best position for getting pregnant. With the woman on her back and her partner on top, it is thought that gravity will assist the sperm to swim upwards towards the egg.
