Human ovulation captured on film

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.

The essential components of the human cardiovascular system are the heart, blood and blood vessels. It includes the pulmonary circulation, a "loop" through the lungs where blood is oxygenated; and the systemic circulation, a "loop" through the rest of the body to provide oxygenated blood.

Carpal tunnel surgery, also called carpal tunnel release (CTR) and carpal tunnel decompression surgery, is a surgery in which the transverse carpal ligament is divided. It is a treatment for carpal tunnel syndrome and recommended when there is static (constant, not just intermittent) numbness, muscle weakness, or atrophy, and when night-splinting no longer controls intermittent symptoms of pain in the carpal tunnel. In general, milder cases can be controlled for months to years, but severe cases are unrelenting symptomatically and are likely to result in surgical treatment.

What is
What is "Endometriosis" and what are the "Endometriosis Symptoms" ? samer kareem 2,048 Views • 2 years ago

Endometriosis (en-doe-me-tree-O-sis) is an often painful disorder in which tissue that normally lines the inside of your uterus — the endometrium — grows outside your uterus. Endometriosis most commonly involves your ovaries, fallopian tubes and the tissue lining your pelvis. Rarely, endometrial tissue may spread beyond pelvic organs. With endometriosis, displaced endometrial tissue continues to act as it normally would — it thickens, breaks down and bleeds with each menstrual cycle. Because this displaced tissue has no way to exit your body, it becomes trapped. When endometriosis involves the ovaries, cysts called endometriomas may form. Surrounding tissue can become irritated, eventually developing scar tissue and adhesions — abnormal bands of fibrous tissue that can cause pelvic tissues and organs to stick to each other.

Near the end of diastole, the ventricles nearly fill with blood, and then the atria contract, adding even more volume to the ventricles. The volume of blood in the ventricles at the end of diastole is referred to as the end-diastolic volume. The other phase of the cardiac cycle is called systole.

Blood Flow Through the Heart
Blood Flow Through the Heart samer kareem 6,347 Views • 2 years ago

Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.

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.

Addison Disease
Addison Disease samer kareem 3,226 Views • 2 years ago

Addison's disease is a disorder that occurs when your body produces insufficient amounts of certain hormones produced by your adrenal glands. In Addison's disease, your adrenal glands produce too little cortisol and often insufficient levels of aldosterone as well. Also called adrenal insufficiency, Addison's disease occurs in all age groups and affects both sexes. Addison's disease can be life-threatening. Treatment for Addison's disease involves taking hormones to replace the insufficient amounts being made by your adrenal glands, in order to mimic the beneficial effects produced by your naturally made hormones.
