An Argentinian review of multiple animal studies is suggesting that antihistamines, found in common allergy medications, may affect male fertility. The study, published in the journal Reproduction, found that antihistamine use could decrease sperm motility and alter sperm morphology.
The study found several papers that reported impaired testicular function in animal studies after antihistamine exposure. These papers found that …
