Even water based ones have chemicals that arent good for sperm.
I said the birth control thing because many teens read the boards and I didnt want them getting ideas that lube could be used as a form of birth control. I tend to cover all my bases when it comes to making sure info isnt used in the wrong ways.
Actually women produce the best lube of all(unless of course tests have been done that shows there are antibodies in the natural lube). One's best bet is to try to stay away from lubes and try for natural. If not then the one already listed PreSeed is so far the one of the best marketed safe lubes for sperm. Though I have in reading up some more found two more lubes that are ok to use. One is Femglide and Slippery Stuff
Most infertility doctors(and the ones I have had to deal with) say the following. Also there are many infertility sites that also say it. I have gotten the info here from various sites. A simple search on sexual lubricants and the effects on sperm or can lubricants effect sperm brought up great info.
Most lubricants used with sexual intercourse have a toxic effect on the sperm.
In a control-based study, they analysed the effect of adding four lubricants: KY jelly, baby oil, olive oil and saliva on sperm motion in 16 samples from patients undergoing infertility investigations. Sperm samples were prepared prior to mixing with lubricants. Motility rates were determined using computer-assisted semen analysis after 5, 15 and 30 min. All lubricants except baby oil significantly decreased percentage progressive motility, progressive velocity, curvilinear velocity and lateral head displacement at 12.5% concentration. At a lower concentration of 6.25%, both olive oil and saliva still significantly reduced progressive motility parameters, while KY jelly diminished head movement parameters. Hence, even at these very low concentrations, sex lubricants impair sperm motility and thus may adversely affect fertility.
Lubricants aid in intercourse, but not in sperm travel through the cervix. Most over the counter lubricants are not "sperm friendly" -- meaning that using them is likely to kill off some sperm. In most cases, one needs to weigh the benefits against the risks . . . it may well be worth losing a few sperm to make it possible to complete intercourse
There is a great book that both your and your wife should read. Taking Charge Of Your Fertility by Toni Weschler. It has some great info on there. Some little tricks that can help increase your wife's own natural lube and increase your chances of getting pregnant.
