This "water" keeps you healthy but it kills men

Recently, a research team led by Susan Deti and Russ Hauser from Harvard University conducted a study on 168 adult men and found that a chemical called "diethyl phthalate" contained in perfume can damage the DNA of adult male sperm. They also said that this substance is usually contained in cosmetics such as soap and perfume used by women or some other aromatic products.

Soaps and perfumes can damage male sperm DNA, leading to an increase in male infertility. Is this just a rumor or a fact? Is it just one person's opinion or a fact recognized by the industry?

Infertility expert: Diethyl phthalate has no effect on sperm

Among the chemicals that affect male sperm, benzene, sulfur, bromine, ethane, etc. have more obvious effects, while "diethyl phthalate" has no adverse effects on male sperm. However, it is certain that the current male infertility rate has indeed increased compared to the past, reaching 30% of the total, and the density of male semen has also decreased from 60 million per milliliter to 20 million now. The quantity and quality of male sperm have decreased a lot compared to the past.

"Male sperm is different from other organs in the human body. It is particularly sensitive to the environment. The factors that cause the increase in male infertility can be summarized as follows: smoking, alcoholism, work stress, taking saunas, tight jeans, etc. Of course, air pollution, radioactive substances, etc. can also cause male infertility." Dr. Shi Wei of Shanghai Ji'ai Infertility Clinic summarized the reasons for the increase in male infertility.

Organic chemistry expert: Diethyl phthalate does not accumulate in the human body

"Diethyl phthalate is produced in tens of thousands of tons. If it affects the DNA of male sperm, wouldn't all the workers in those factories become infertile? Besides, we often use this substance in our experiments and there is no problem. We have never heard of such a saying." This was the first reaction of Dr. Lu Long, deputy director of the Shanghai Institute of Organic Chemistry of the Chinese Academy of Sciences, after hearing the news. In addition, this substance is easy to volatilize and will not accumulate in the human body. I have never heard of this substance in soaps and perfumes in my country.
