Sex breakthrough: the 5 most incredible scientific achievements of the recent yearsPictolic
Science in recent years stepped forward, she literally broke into the future, and covered us with new discoveries. Some of them will be forgotten, the other will become the Foundation for new achievements.
At the end of 2014, the physicians of South Africa performed the world's first successful transplantation of a donor penis 21-year-old man in the hospital Cape town. After a failed ritual circumcision, doctors were forced to amputate the patient's penis for the sake of his life. Unfortunately for South Africa is not so rare.
In order to transplant the unfortunate new penis, Dr. Andre van der Merwe and his surgical team used a technology similar to that used for surgery. Tiny blood vessels and nerves are connected by microsurgical manipulations. The surgery lasted 9 hours. After only three months after surgery, Dr. van der Merwe said that the man with his "new member" and his girlfriend expecting a baby.
A similar operation was conducted in China, where the man in the accident lost his penis. Unfortunately, due to psychological problems, the graft had to be removed two weeks after surgery.
First appeared in the early XX century, condoms made of latex are the means of contraception you trust the most. However, this does not mean that latex condoms never fail. First, people allergic to latex can't use them. Secondly, many people find them uncomfortable. And researchers have looked for alternatives.
Contraceptive has been developed by scientists at the University of Wollongong in Australia, the money allocated by the bill and Melinda gates Foundation.
The research team led by Robert Gorkina used heavy-duty material of the new generation hydrogel, which looks and feels like natural human tissue. One of the added benefits of the hydrogel before the latex is the ability to deliver in the body of drugs, for example, excitatory.
The latest generation of sex toy requires more than just a hundred modes of vibration medical-grade silicone and a nice size and shape. New vibrator, developed by a team of two physicists, detects the slightest reduction of the vaginal walls and adapts to the rhythm of your body.
Thus, the rhythm toys "adjusted" by the contractions of the vagina and does exactly as you need. Be in sync with the time, when women have an orgasm occurs, it enhances the experience and extends it. The vibrator ROM, complex computer code.
Aplasia of the uterus and vagina (Rokitansky syndrome-Kustner) is a rare congenital genetic abnormality, characterized by a primary absence of the uterus and 2/3 of the upper parts of the vagina. This preserves the normal development of external genitalia, which helped doctors to help people with this difficult disease to improve quality of life.
Four girls aged 13 to 18 years took samples of tissue from the outer genitals, and these cells formed the basis for lab-grown vaginas. The researchers successfully grew a vagina, but also implanted them girls. Surgeons created a channel in the pelvic region of female patients and sewed reproductive structures.
In his article in the Lancet program Director Dr. Anthony Atala writes: "This is the first study which shows that vaginal organs can be created in the laboratory and successfully implanted in the human body".
When we say "contraceptive", then imagine, as a rule, either a condom or pills. Our head just does not come the way a tiny valve on the male body that can be turned on or off. German Clemens Bimek in 2000, he patented a device called the SLV — gadget the size of a coin, which simply allows the man to control the flow of sperm.
I must say, the prospect to implant something into the penis are hardly capable to please men. But there are analogs — for example, a special gel Vasalgel, which fill the ejaculatory canal, through which the sperm into the ejaculate. Upon contact with living tissues, the substance becomes solid and blocks the release of spermatozoa in the ejaculate.
If you enter another substance that it will dissolve then that blocks the ducts, and the man can conceive. It is believed that the effect of the gel Vasalgel last at least ten years.
