Study says Sperm Cell Functions can be disrupted by some sunscreen lotion’s contents

United States: A new study of which the results were presented, a day before yesterday (1st April), at the 91th Annual Meeting of Endocrine Society in Boston, shows that the Sunscreen lotions’ common ingredients of many ultraviolet- UV filtering chemicals interfering with the functions of the human sperm cells, and also some take off the effect of the female hormone progesterone.

As per the senior investigator of the study- Niels Skakkebaek, who is also MD, DMSc, and a University of Copenhagen’s Professor and also a researcher at the Rigshospitalet- based Hospital of said Copenhagen University, that “these results are of concern and might explain in part why unexplained infertility is so prevalent,”.

And as such, and also reportedly as seen in the United States, Denmark and other countries that the UV filter chemicals have been found in the blood samples of the human beings and also in their Urine Samples as much as in ninety- five percent.

It was seen that in the study, the researchers have tested about Twenty- nine of the thirty- one UV filters which are permitted in United States or European Union- EU to be used in sunscreens, from the health sperm cells and from the fresh semen samples obtained from several healthy human donors.

From such twenty- nine UV filters which were tested by the author and researchers, they found that thirteen or forty- five per cents of such UV filters inducing calcium ion influxes in the sperm cells, as such interfering with the normal sperm cell functionalities.

Also notably, the researchers found 8 of the 13 UV filters which disrupting sperm cell function, and also approved for the use in the United States, and they are avobenzone, octinoxate, meradimate, homosalate, octocrylene, oxybenzone octisalate, and padimate O.
