Men and women have anatomical differences when it comes to genitals, but orgasms are fundamentally very similar. The female orgasm lasts longer than the male, ranging about 20 seconds compared to 3 to 10 seconds, but men do experience more orgasms.

This video, created by Nucleus Medical Media, shows a coronary artery bypass graft (CABG) procedure used to combat coronary artery disease. Beginning with a midline sternal incision, the heart is connected to a perfusion machine which will take over the duties of the heart while the surgery takes place. Two different grafts are used to bypass the blocked coronary arteries: the internal thoracic artery from inside the chest wall, and the saphenous vein from the leg. After the procedure, the heart is shocked to restart its beating. A drainage tube is left at the incision site to drain away excess fluid. The animation continues to show two other types of approaches to a coronary artery bypass graft, off-pump bypass surgery and minimally invasive bypass surgery.
This is similar to the procedure performed on former president Bill Clinton and former California governor Arnold Schwarzenegger.

Vaginal delivery is the most common and safest type of childbirth. When necessary in certain circumstances, forceps (instruments resembling large spoons) may be used to cup your baby's head and help guide the baby through the birth canal. Vacuum delivery is another way to assist delivery and is similar to forceps delivery. In vacuum delivery, a plastic cup is applied to the baby's head by suction and the health care provider gently pulls the baby from the birth canal.
Dr. Debbie Song at Gillette Children's describes in detail selective rhizotomy surgery.
A selective dorsal rhizotomy is an operation performed to treat spasticity. It is thought that high tone and spasticity arise from abnormal signals that are transmitted through sensory or dorsal nerve roots to the spinal cord. In a selective dorsal rhizotomy we identify and cut portions of the dorsal nerve roots that carry abnormal signals thereby disrupting the mechanisms that lead to spasticity. Potential patients go through a rigorous assessment that includes an in-depth gait and motion analysis as well as a physical therapy evaluation.
They are evaluated by a multidisciplinary team that includes a pediatric rehabilitation doctor, a neurosurgeon, and an orthopedist, Appropriate patient selection is vital. Ideal candidates for selective dorsal rhizotomy are children who are between four and ten years of age, have a history of being born prematurely, and have a diagnosis of diplegia cerebral palsy. These patients usually walk independently or with the assistance of crutches or a walker. They typically function at a level one, two, or three in the gross motor function classification system or gmfcs. A selective dorsal rhizotomy involves the coordinated efforts of the neurosurgery, physiatry, anesthesia and nursing teams. The operation entails making an incision in the lower back that is approximately six to eight inches long. We perform what we call a laminoplasty in which we remove the back part of the spinal elements from the lumbar one or l1 to l5 levels. At the end of the procedure the bone is put back on. We identify and open up the Dural sac that contain the spinal fluid spinal cord and nerve roots. Once the Dural sac is opened ,we expose the lumbar and upper sacral nerve roots that transmit information to and from the muscles of the lower extremities.
At each level we isolate the dorsal nerve root, which in turn is separated into as many as 30 smaller thread light fruitlets.
Each rootlet is then electrically stimulated. Specialized members of the physiatry team look for abnormal responses in the muscles of the legs as each rootless is being stimulated. If an abnormal response is observed then the rootlet is cut.
If a normal response is observed, then the rootlet is not cut. We usually end up cutting approximately 20 to 40 percent of the rootlets. The Dural sac is sutured closed and the l1 through l5 spinal elements are put back into anatomic position, thus restoring normal spinal alignment. The overlying tissues and skin are then closed and the patient is awoken from surgery. The entire operation takes between four and five hours. A crucial component to the success of our rhizotomy program is the extensive rehabilitation course following surgery. With their tone significantly reduced after a rhizotomy, patients relearn how to use their muscles to walk more efficiently through stretching, strengthening, and gait training. Approximately one to two years after a rhizotomy patients undergo repeat gait and motion analysis. The orthopedic surgeons assess the need for interventions to correct bone deformities, muscle contractures, poor motor control, impaired balance, or other problems related to cerebral palsy.
At Gillette we work closely with patients and families to ensure that our selective dorsal rhizotomy program meets their goals for enhancing their function and improving their quality of life.

To record the sequence, Stephan Gordts and Ivo Brosens of the Leuven Institute for Fertility & Embryology in Belgium performed transvaginal laparoscopy, which involves making a small cut in the vaginal wall and observing the ovary with an endoscope.
"This allows us direct access to and observation of the tubo-ovarian structures without manipulation using forceps," says Gordts.
For the photos of ovulation, which only accidentally captured the critical moment, Jacques Donnez at the Catholic University of Louvain (UCL) in Brussels, Belgium, used gas to distend the organs for photography. However, Gordts and Brosens planned the procedure to coincide with ovulation and used saline solution to "float" the structures.
Perfect timing
Observation was timed for the day of the peak of the patient's luteal hormone cycle. Ovulation was predicted to occur on the evening of the day of the LH peak, and the endoscope introduced at 6 pm.
A small amount of saline was used to float the opening of the fallopian tube, its fimbriae (the "fingers" that sweep the egg into the tube) and the ovary itself. This gives a more natural appearance than gas, says Gordts.
In the video, the fimbriae can be seen sweeping in time with the patient's heartbeat. A mucus plug can be seen protruding from the ovary – this contains the egg.
"The ovum is not captured 'naked'," says Gordts. "There is no eruption like a volcano."
Gordts says that in clinical practice it is not easy to organise the observation of ovulation. "We were probably lucky to be successful at our first attempt," he says.
