FAQ

Factors such as pregnancy, childbirth, aging,being overweight, and abdominal surgery such as cesarean section, often result in the weakening of the pelvic muscles. This can be assessed by either digital examination of vaginal pressure or using a Kegel perineometer. Kegel exercises are useful in regaining pelvic floor muscle strength in such cases.

Urinary incontinence

Pelvic floor exercises are recommended for women with urinary incontinence of the stress, urge, or mixed types. There is tentative evidence that biofeedback may give added benefit when used with pelvic floor muscle training.

Pelvic prolapse

There is some evidence showing a positive effect of pelvic floor exercises on the symptoms of prolapse and its severity.

Sexual function

In 1952, Dr. Kegel published a report in which he claimed that the women doing his exercises were orgasming more easily, more frequently and more intensely: "it has been found that dysfunction of the pubococcygeus exists in many women complaining of lack of vaginal feeling during coitus and that in these cases sexual appreciation can be increased by restoring function of the pubococcygeus." There is controversy over the precise effects of the PC muscle on orgasmic response.

Though most commonly used by women, men can also use Kegel exercises. Kegel exercises are employed to strengthen thepubococcygeal muscle and other muscles of the pelvic diaphragm. Kegels can help men achieve stronger erections, maintain healthy hips, and gain greater control over ejaculation. The objective of this may be similar to that of the exercise in women with weakened pelvic floor: to increase bladder and bowel control and sexual function.

Urinary incontinence

After a prostatectomy there is no clear evidence that teaching pelvic floor exercises alters the risk of urinary incontinence (leakage of urine).

Sexual function

A paper found that pelvic floor exercises could help restore erectile function in men with erectile dysfunction. There are said to be significant benefits for the problem of premature ejaculation from having more muscular control of the pelvis. 

The well-known Chinese “four great jades” are “Hetian jade” of Xinjiang, “Xiuyan jade” of Xiuyan town of Liaoning province, “Dushan jade” of Nanyang town of Henan province and “calaite” of Yun town of Hubei province.

Hetian jade

Hetian jade is mainly distributed in Xinjiang’s Shache — Tashikuergan town, Hetian — Yutian town and Qiemo town. This kind of jade contains tiny diopside, ophiolite, black lead and magnet and other minerals. The colors of the jade vary. There are white, turquoise, black and yellow and other colors. Most of the jade is monochrome jade, and a few are variegated. The quality of the jade is semitransparent, and after polishing, the colors are similar to that of fat. Its rigidity ranges from 5.5 degrees to 6.5 degrees. Hetian jade can usally be found mountains’ rock where the altitude is between 3,500 meters to 5,000 meters.

The breed of Hetian jade can be divided into eight species according to different colors and degrees of purity. They are white jade, suet white jade, white-greenish jade, gray jade, yellow jade, sugar jade, dark jade and jasper

Dushan jade

Dushan jade is also known as “Nanyang jade” or “Nan jade”, which is produced in Dushan just north of Nanyang city. As one of the Chinese four great jades, the quality of Dushan jade is tough and dense, exquisite, soft and moist, and its color is transparent. It has six colors: green, white, yellow, purple, red and black.

Calaite

Calaite is similar to emerald. It got its name because its color and shape is like a dark green pinecone. Calaite is one of the rare valuable diamonds in the world, and the goods produced with calaite have become an important collectable.

People have always been attracted to its green color and the grain of calaite. In ancient times, people related calaite with religion and superstition. In Tibet, people especially respect calaite. They see calaite as a divine decorative accessory, which can be used for rituals.

The color of calaite may differ because of the different elements it contains. Calaite will appear blue in color if it contains coppery oxide, and it will appear green if it contains iron oxide. The color of calaite is an important factor which can affect its quality.
