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.

Spermatocele
Spermatocele samer kareem 26,375 Views • 3 years ago

A spermatocele (SPUR-muh-toe-seel) is an abnormal sac (cyst) that develops in the epididymis — the small, coiled tube located on the upper testicle that collects and transports sperm. Noncancerous and generally painless, a spermatocele usually is filled with milky or clear fluid that might contain sperm. The exact cause of spermatoceles is unknown but might be due to a blockage in one of the tubes that transports sperm. Spermatoceles, sometimes called spermatic cysts, are common. They typically don't reduce fertility or require treatment. If a spermatocele grows large enough to cause discomfort, your doctor might suggest surgery.

Majority of patients these days prefer PCNL ( Minimal Invasive Telescopic removal of kidney stones broken with lithoclast, removed through a button hole incision ). This patient with a big stone in the pelvis of the kidney wanted it open only so I did an open pyelolithotomy for this patient after a long time as I use to do it in routine in the past. Except for the long incision and scar as compared to PCNL the recovery time was the same and patient went home third day happily walking and eating.

The Perfect Breast Shape
The Perfect Breast Shape samer kareem 27,990 Views • 3 years ago

Shut the front door: Scientists have finally found the perfect breasts. No, they weren't hiding in the Amazon or roving solo across the Sahara (although we have no doubt there are women in both the Amazon and the Sahara who have magnificent mammaries); it turns out these perfect breasts were hiding in a plastic surgeon's office this whole time! Now, before you get all worked up, the American Society of Plastic Surgeons (ASPS) would like you to know that the super-fake looking plastic breasts of yore are not actually what people think are most attractive now. According to a study published in the Journal of Plastic and Reconstructive Surgery—which involved asking over 1,300 people to look at pictures of naked boobies and rank them by hotness (stop laughing, this is serious research!)—people preferred a more "real" and "normal" look from their silicone, with the ideal breast shape having a 45:55 ratio. People said the best chests have 45 percent of the fullness above the nipple line and 55 percent of the fullness below, in a slightly teardrop shape. Researchers noted this preference remained consistent across gender, racial, and ethnic groups with the 45:55 ratio favored by 87 percent of women in their 30s, 90 percent of men, and 94 percent of plastic surgeons.
