Abstract
AbstractLubricants play a pivotal role in human reproductive health, particularly concerning their impact on sperm parameters. In this systematic review, we assess the implications of both synthetic and natural or organic lubricants on sperm health and fertility, based on a compilation of 20 distinct studies. Synthetic lubricants, including K‐Y Jelly, Replens, and Astroglide, predominantly containing ingredients like methylparaben and glycerin, have been linked to detrimental effects on sperm motility and chromatin integrity. Chemical characteristics, notably osmolality and pH, are central to understanding these effects. Despite the World Health Organization's osmolality recommendation of 380 mOsm/kg, many commercial products surpass this. Natural solutions offer varied results, while olive oil exhibits unfavorable effects on sperm health, egg white proves non‐toxic, potentially benefitting sperm health. Conversely, Pre‐Seed, widely endorsed in the research community, generally demonstrates minimal adverse impact on sperm. The review highlights the significance of lubricant selection in evidence‐based reproductive strategies.
