Using paracetamol during pregnancy? Ditch it now. This medication is linked to reduced sex drive and hostile behavior among male children. This common medication considered "safe" to use during pregnancy is taken to treat pain and fevers. However, a research conducted by University of Copenhagen, Denmark proves that it may have negative affects on your male child. Researchers concluded that this drug can hinder the development of the male sex hormone testosterone, increasing the chances of malformation of the testicles in the unborn child. This is extremely worrying because testosterone is the primary hormone that develops the male body and programming of the brain. Read the rest of the results from this study here.
