Saliva is perfectly safe to supplement your own
natural lubrication. But bacteria and viral particles can easily be carried from
the saliva to your genitals, potentially causing a dangerous infection down
below.
Spit is probably the world's oldest sex lube.
Numerous studies over the years have
evaluated the effect of different lubricants and even saliva on sperm. Many
couples rely on lubricants, such as KY-Jelly, to overcome issues with vaginal
dryness. In addition, the fertility drug clomiphine (Clomid) has been shown to
decrease cervical mucus in many women.
A 1998 study in the medical journal Human
Reproduction examined the effect of KY jelly, baby oil, olive oil and saliva on
sperm motility (movement) along with other semen characteristics. Each of the
tested lubricants had serious effects on sperm, the most toxic of which was
saliva. The least detrimental of those tested was baby oil. The authors
concluded, “we would recommend that couples - especially those having
difficulty in conceiving - should be aware of the detrimental effects of such
lubricants and avoid their use.”
