Sufficient lubrication, the secretion of fluid from the vaginal walls and glands, is an essential part of enjoying sex and when getting pregnant.

And when trying to conceive having a moist vagina does not just feel better, it might actually improve your chances of getting pregnant.
Up to 50% of couples report problems with proper lubrication
But when you are trying to get pregnant, there is also concern about the sperm count -- every single sperm counts and you don't want to do anything that impairs the sperm count and/or function. Studies have shown that saliva is not a sperm-friendly medium, nor is water. And anything petroleum-based, such as Vaseline, should be avoided.

Artificial lubricants (such as KY Jelly, Astroglide, and Femglide) have been found in several studies to have a negative effect on sperm.

There is only one lubricant called called "PreSeed" which has been found to have the least adverse effect on sperms. Pre~Seed is the first "sperm-friendly" intimate moisturizer that mimics natural body secretions to relieve vaginal dryness while providing an optimal sperm environment. Pre~Seed's moisture is delivered in a fluid with the same pH and osmolarity as semen, so as not to harm sperm, and to be mild to a woman's body.

Pre~Seed contains a naturally occurring bioactive plant sugar (arabinogalactan) which provides antioxidant support to cells. Antioxidant levels can be severely decreased in semen from men with fertility problems

Here are some suggestions for doing without an artificial lubricant:

  • Foreplay should be an essential part of your interaction every time you have sex. Allow for sufficient time for foreplay
  • Start with a romantic evening.
  • Massage each other.
  • Talk sweetly to each other.
  • Touch each other's body parts, except for the genitalia
