The Daily Mail recently highlighted the question of whether couples trying to conceive would benefit from using a sperm friendly lubricant.
We always advise couples we see who are trying for a baby not to use general lubricants during their love-making and not to use saliva. Both can harm sperm. However, if vaginal dryness is an issue, a sperm-friendly lubricant such as Pre Seed or Conceive Plus may help. The PH balance of the lubricant may balance the acid- alkaline balance of the more acid vagina which traditionally repels the more alkaline sperm. Increased moisture may also help the sperm to swim up the cervix.
A 2014 study measured the effect on sperm function of 11 lubricants, including some that claimed to boost fertility. It found that two – Pre-Seed and Conceive Plus – improved ‘motility’, a measure of how much sperm moves. All the others had a detrimental effect.
