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.

Symptoms of Alcoholic Liver Disease
Symptoms of Alcoholic Liver Disease samer kareem 2,741 Views • 3 years ago

Alcoholic hepatitis is inflammation of the liver caused by drinking alcohol. Alcoholic hepatitis is most likely to occur in people who drink heavily over many years. However, the relationship between drinking and alcoholic hepatitis is complex. Not all heavy drinkers develop alcoholic hepatitis, and the disease can occur in people who drink only moderately. If you're diagnosed with alcoholic hepatitis, you must stop drinking alcohol. People who continue to drink alcohol face a high risk of serious liver damage and death.

HIV / AIDS
HIV / AIDS samer kareem 2,686 Views • 3 years ago

HIV stands for human immunodeficiency virus. If left untreated, HIV can lead to the disease AIDS (acquired immunodeficiency syndrome). Unlike some other viruses, the human body can’t get rid of HIV completely. So once you have HIV, you have it for life. HIV attacks the body’s immune system, specifically the CD4 cells (T cells), which help the immune system fight off infections. If left untreated, HIV reduces the number of CD4 cells (T cells) in the body, making the person more likely to get infections or infection-related cancers. Over time, HIV can destroy so many of these cells that the body can’t fight off infections and disease. These opportunistic infections or cancers take advantage of a very weak immune system and signal that the person has AIDS, the last state of HIV infection. No effective cure for HIV currently exists, but with proper treatment and medical care, HIV can be controlled. The medicine used to treat HIV is called antiretroviral therapy or ART. If taken the right way, every day, this medicine can dramatically prolong the lives of many people with HIV, keep them healthy, and greatly lower their chance of transmitting the virus to others. Today, a person who is diagnosed with HIV, treated before the disease is far advanced, and stays on treatment can live a nearly as long as someone who does not have HIV.

Natural Childbirth
Natural Childbirth samer kareem 4,511 Views • 3 years ago

A natural, unmedicated approach to labor and birth will suit you best if you want to remain in control of your body as much as possible, be an active participant throughout labor, and have minimal routine interventions such as continuous electronic monitoring. If you choose to go this route, you accept the potential for pain and discomfort as part of giving birth. But with the right preparation and support, women often feel empowered and deeply satisfied by natural childbirth.

Questions about penile implantation surgery.
Questions about penile implantation surgery. samer kareem 7,696 Views • 3 years ago

The inflatable penile prosthesis consists of two attached cylinders -- a reservoir and a pump -- which are placed surgically in the body. The two cylinders are inserted in the penis and connected by tubing to a separate reservoir of saline. The reservoir is implanted under the rectus muscles in the lower abdomen. A pump is also connected to the system and sits under the loose skin of the scrotal sac, between the testicles. This penile prosthesis is referred to as a 3-piece inflatable penile prosthesis, due to the three different components. A 2-piece inflatable penile prosthesis consists of only two components: the attached cylinders and the combined reservoir and pump unit. Instead of the reservoir being placed behind the groin, it is combined with the pump into one housing unit that fits comfortably within the scrotum. The advantage of a 2-piece prosthesis in that the surgery is shorter and less complicated and there is no device parts in the abdomen. The disadvantage of the 2-piece prosthesis is that the smaller reservoir may not result in adequate erections in some men. To inflate the prosthesis, the man presses on the pump. The pump transfers saline from the reservoir to the cylinders in the penis, inflating them and causing an erection. Pressing on a deflation valve at the base of the pump returns the fluid to the reservoir, deflating the penis and returning it to the normal flaccid state.
