Arousal Fluid

A woman’s arousal fluid comes from the Bartholin's glands (vesibular glands) located just inside the left and right lower side of the vaginal wall. Arousal fluid lubricates the labial opening of the vagina to make intercourse more comfortable. It is does not have a role in sperm survival or transport.

Arousal fluid is only present during sexual stimulation, a few minutes after orgasm, and during breastfeeding. Arousal fluid feels slightly slippery and is cloudy or opaque in colour. It disappears quickly once stimulation for its production is stopped. With careful attention a woman quickly learns to distinguish when she is noticing arousal fluid and when she is noticing cervical mucus. Remember, cervical mucus appears regardless of arousal. Arousal fluid appears only when there is arousal and for the duration of the arousal. If you have a doubt as to whether you are observing arousal fluid or cervical mucus apply the ‘if in doubt’ rule and consider yourself of peak fertility and count three.

Male arousal fluid is produced by the Cowper's gland located just below the prostate gland. Male arousal fluid is also known as preseminal or preejaculatory fluid. It is produced in response to sexual stimulation and provides lubrication for intercourse.  It also alkalinizes the urethra to make a favorable environment for sperm passage. A man's arousal fluid is considered fertile, because it may contain viable sperm.
