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.

Swallowing Semen, Is that dangerous?
Swallowing Semen, Is that dangerous? samer kareem 20,231 Views • 2 years ago

Ejaculating into a partner’s mouth is a common practice during oral sex/fellatio. In a safe situation (where there is no danger of catching an STD), the semen-receiving partner may choose to spit the semen out, or to swallow it. Before you engage in fellatio, I’d recommend that you and your partner both get tested for sexually transmitted infections (STIs). If not, please use barriers for oral sex and abstaining from making contact with ejaculate. Semen is mostly water, but also contains amino acids and protein, sugars such as fructose and glucose, minerals such as zinc and calcium, vitamin C, and a few other nutrients. Sperm cells themselves make up less than one percent of semen. Semen is edible, and if swallowed, will travel down the esophagus and into the stomach, where it will be digested in the same way that food is. You can never get pregnant by swallowing semen. Some people accept the taste of semen, but others complain that swallowing semen can give them an upset stomach. In rare cases, you may have an allergy to the proteins found in semen. What does It Taste Like? The taste of semen varies. Bitter, sweet, metallic. So, one may expect to find the taste of semen anywhere from enjoyable to tasteless to disgusting. But there is a way of controlling the taste of semen, which is through diet. Keep track of the diet, and communicate with the partner about when it tastes better or worse.

Pulmonary Arterial Hypertension
Pulmonary Arterial Hypertension samer kareem 1,620 Views • 2 years ago

The average time from symptom onset to diagnosis has been reported to be approximately 2 years. Despite recent attempts at increasing the awareness of pulmonary arterial hypertension (PAH), especially associated PAH (APAH), this delay in diagnosis has not changed appreciably in recent years. Early symptoms are nonspecific. Often, neither the patient nor the physician recognizes the presence of the disease, which leads to delays in diagnosis. Complicating matters, idiopathic PAH (IPAH) requires an extensive workup in an attempt to elucidate an identifiable cause of the elevated pulmonary artery pressure. The most common symptoms and their frequency, reported in a national prospective study, are as follows: Dyspnea (60% of patients) Weakness (19%) Recurrent syncope (13%) Additional symptoms include fatigue, lethargy, anorexia, chest pain, and right upper quadrant pain. Cough, hemoptysis, and hoarseness are less common symptoms. Women are more likely to be symptomatic than men.

Upper gastrointestinal bleeding (sometimes upper GI, UGI bleed, Upper gastrointestinal hemorrhage, gastrorrhagia) refers to bleeding in the upper gastrointestinal tract, commonly defined as bleeding arising from the esophagus, stomach, or duodenum. In fact, the proportion of UGIB cases caused by peptic ulcer disease has declined, a phenomenon that is believed to be due to the use of proton pump inhibitors (PPIs) and H pylori therapy. Duodenal ulcers are more common than gastric ulcers, but the incidence of bleeding is identical for both.

Biceps tenodesis surgery is performed when the biceps tendon is damaged, or the rotator cuff tendon or cartilage ring in the shoulder is torn. The biceps tendon is a strong rope‐like structure connecting the upper end of the biceps muscle to the bones in the shoulder. In biceps tenodesis surgery, the biceps tendon is separated from the shoulder and reattached to the humerus, or the upper arm bone.
