Let women only have 3 menstrual periods a year Australia's new drug YazFlex starts to be sold in pharmacies

As a unique physiological characteristic of women, menstruation sometimes makes women fall into embarrassing situations, causing inconvenience to work and life. A new drug YazFlex developed by Australian researchers since 2012 that allows women to have only three menstrual periods a year has been successfully launched. It is said that this medicine will not damage women's fertility, long-term use and contraceptive effect, when a woman wants a baby, just stop the drug. Since September 3 this year, this drug has been sold in major pharmacies in Australia, causing a sensation among Australian women, and many women expressed their willingness to try it.


The scientific name of this medicine is YazFlex, and its predecessor is a contraceptive pill called Yaz. Like most contraceptives, Yaz cannot be taken continuously for a long time. The high doses of estrogen contained in the medicine can make women lose their ability to conceive. Later, an Australian drug research and development company carried out research and development upgrades to Yaz, and developed it into a new drug that can inhibit menstruation. The famous German Bayer Pharmaceutical Company undertook the production task of this medicine.

Yaz Flex is packed in a palm-sized pill box. This inconspicuous box has the ability to count and control the distribution of pills. Each box contains 120 tablets, and only 3 tablets are spit out per day. People who take the drugs cannot eat more. Same, less. One tablet is not enough, the automatic alarm function of the medicine box will beep until the user takes the medicine obediently.


Dr. Deborah Bateson, the medical director of the Family Planning Department of NSW, Australia, praised the drug for "reducing a lot of worries for women." He said, “Deciding on the number of menstruation by yourself has made women less troublesome. A survey of 70 people we have done shows that more than XNUMX% of women are willing to take this drug.” Deborah said that reducing the number of menstruation is not harmful to women, but Can protect women's fertility.

"A woman has an average of several hundred menstruation in her lifetime. After each period, the wall of the uterus becomes thinner until the menstruation disappears. Of course, after the disappearance of the menstruation, women basically lose their fertility. YazFlex reduces the number of menstruation in women every year. To a certain extent, the menstrual cycle of women’s life is lengthened, and the age of women’s childbearing is prolonged. For those middle-aged women who are devoted to their careers and have no time to have children, the advent of YazFlex is good news."

Rod Barbor, a professor of obstetrics and gynecology at a public hospital in NSW, also thinks YazFlex is a good medicine. "Medical studies in many countries have confirmed that it is safe to reduce the number of menstrual cycles in women, but there has been no approved way to reduce menstruation. YazFlex provides a good reference."

Taking YazFlex also has side effects, but they are all within a controllable range, such as headache, nausea, chest tightness, depression, irregular bleeding or blood clots, but medical data shows that the probability of these side effects is extremely low.
