A new study from Denmark shows that such widespread painkiller as ibuprofen can have a significant negative effect on male fertility affecting testicular health, altering hormone production and inducing compensated hypogonadism.
For the research, the scientists recruited 31 men aged between 18 and 35 half of whom received a moderate dose (600 mg, or three tablets) of the drug daily during six weeks. The other group received placebo. Within 2 weeks, the men who were taking ibuprofen on a daily basis demonstrated an increase in luteinizing hormones.
The team writes in their paper: “It is also of concern that men with compensated hypogonadism may eventually progress to overt primary hypogonadism, which is characterized by low-circulating testosterone and prevalent symptoms including reduced libido, reduced muscle mass and strength, and depressed mood and fatigue.”
A new study from the University of California finds that chemicals in such common household products as hand wipes, disinfectants, and mouthwash, contain “quats” (quaternary ammonium compounds), destroying germs and causing infertility in women.
A team of researchers looked over 1,600 compounds containing quats. They discovered that these chemicals really block human mitochondria and make them working incorrectly. They also affect the hormone estrogen, which plays a vital part in women falling pregnant.
Dr. Gino Cortopassi, co-author of a study on the chemicals says: “However we don’t yet know what levels these compounds reach in humans.’ Quats, used since the 1940s, are good disinfectants because they dissolve the cell membranes of germs found in our homes. They work the same way to kill bugs in our mouths.”
A new study by Danish scientists has shown that the chemical substances that protect the skin from harmful UV rays, may be the reason for male infertility.
Sunscreen can deprive a man of having children, destroying sperm cells. The fact is that almost half of the substances present in the composition of these funds mimic the action of the female hormone progesterone, which prevents the normal functioning of male germ cells. Lotion absorbed by the skin, whereupon the chemicals get into the bloodstream.
Niels Skakkebaek, a professor of the University of Copenhagen, said that these results are interesting and may partly explain why unexplained infertility is so common. Professor and his colleagues tested 29 UV filters permitted for use in the manufacture of sunscreens and lotions, for live sperm cells obtained from completely healthy donors. Nearly half of the UV filters have broken function of sperm cells.
Sperm has a special channel, which is a receptor for the female hormone progesterone. 13 filters of all tested violated the vital function of male sex cells – such as the movement of sperm.
Professor Skakkebaek said that this effect began at very low doses of chemicals, lower than levels of certain UV filters found in people after applying sunscreen all over the body.
This proves once again that the principle of “the more – the better” does not work when it comes to health. And when choosing a sunscreen is better to be safe and thoroughly examine its composition.
