28 Rumors said: who lives in Yubei Zhou Min, 28, was a perfume of people, she loves collecting perfumes, like spraying perfume according to different clothing and occasions. But three years of marriage, she has not been pregnant with the baby. Recently I discovered later to the hospital, cause of infertility is likely to be her long spray perfume. Experts remind that contains musk perfume ingredients, long-term use is likely to lead to infertility.

Musk is what?
Natural musk is actually Mammal, musk deer animal (such as forest musk deer, musk deer, musk deer) secretions taken from mature males glands located between the navel and genitals. Musk is these animals to attract the opposite sex tool, ancient China and India are drugs used to collect them, use it to do almost a panacea arrest Han Han rule. Musk later introduced to Europe mainly used as a spice.
Collecting musk need to kill the animals, and the yield is very low, which not only led to high prices musk expensive than gold, more importantly, is greatly threatened the musk deer animal's survival. In 1906, the first human made an important breakthrough in the research component of natural musk, isolated the main component of musk and named musk ketone (muscone, 3- methyl cyclopentadecanolide). Although the late 19th century, animal musk is still widely used, but after that, it began to gradually natural musk is replaced by synthetic musk. By now, almost all synthetic musk up.
Experiments related to pregnancy and musk
The early 1980s, Chong Li Chinese Academy of Sciences for the main component of musk ketone Musk did some experiments. His daily subcutaneous injection of 20 mg or the same volume of musk ketone group solvent has been successfully mated female mice and found that the proportion of pregnant mice musk ketone would drop from 63% -83% of the control group to musk ketone group of 17 % -40%, while progesterone can prevent musk ketone such anti-pregnancy effect. According to the researchers speculate that musk ketone may be to anti-pregnancy effect by inhibiting progesterone levels. However, this study is a component used in the 3-ring enone fifteen artificial musk ketone, musk and the main component of natural 3-cyclopentadecanolide slightly and then the scientists use synthetic 3 - a cyclopentadecanolide same experiment, found that 3-cyclopentadecanolide not have such anti-pregnancy role. Such results are still unable to determine whether natural musk with anti-pregnancy role.
After 1987, a Japanese research team also musk pharmacological properties were studied. This time, scientists use natural musk solution with different concentrations of isolated uterine smooth muscle were soaking experiments, and found that when the concentration of musk solution is 0.1 mg / ml, did promote smooth muscle contraction, but when the concentration rises to 1 when mg / ml, uterine smooth muscle contraction will be suppressed. The results from this point of view, from the simple to talk about concentration musk effect on the uterus may be difficult to predict the outcome.
From the few studies on pregnancy musk impact we can see, musk ketone different structures of animals Pregnance may vary greatly, but natural musk effect on uterine contractions may vary significantly with different concentrations. Most importantly, musk either as raw material or as a cosmetic palace fighting weapons primarily by sniffing functioning, while the above study, and is administered by subcutaneous injection directly into muscle tissue soaked in a solution of musk play a role, this huge difference on the mode of administration may result in significant differences in the results of the absorbed dose and medication.
The above study can only say that one kind of temptation and prompt research direction. There is no sufficient basis Description With musk will to cause abortion.
Perfume used artificial musk
Basically currently used in all kinds of cosmetics, perfume musk up. Artificial musk is widely used in decades, people are constantly monitoring and evaluation of the safety of artificial musk, and process improvements based on the assessment results, the assessment found no musk influential role in pregnancy, there is no report of musk cause abortion.
