Lubes That Kill

If you’re trying to conceive, it may be best to discontinue using certain lubricants.
A new study of commercial sexual lubricants reveals a number of popular brands of lubricants that can hinder sperm activity and forward movement, and even foil conception (now now, gents… it still doesn’t count as a contraceptive). In the study, researchers exposed sperm samples to each lubricant and observed their effects on the sperm after an hour. They found that lubricants such as K-Y Tingling Jelly, K-Y Sensitive Jelly (both no longer available), K-Y Warming Jelly and Astroglide had interfered with sperm motility. The only commercial product that did not adversely affect sperm movement was Pre-Seed, a lubricant marketed as a conception aid. Other oils such as Canola, baby and sesame oils were also tested: sesame oil slowed sperm, canola and baby oil had no effect, while mustard oil happened to increase sperm movement immediately, lasting for at least an hour following initial exposure.
Some fertility specialists recommend mineral oil as a lubricant for couples trying to conceive – both inexpensive and non-toxic.
