What is precum
Precum can be compared to watering of the mouth that happens when hungry person smells aroma of delicious food being cooked and is about to be served. Watering of mouth is compared to precum because as in the hungry person on seeing his favorite sweets or candies there is watering in mouth so too on seeing erotic pictures or talking naughty sex talk or during foreplay.
Precum comes at the beginning of sex. Semen comes at the end of sex.
Precum is watery colorless slightly sticky fluid that oozes out of penis during sexual excitement. Precum is not semen. People often get scared due to the wrong belief that semen has come out.
Purpose of precum
Nature has designed the discharge of precum to act as lubricant. Pre-cum also acts as acid neutralizer. In both male and female watery discharge starts at the time of sexual arousal.
- Sex means friction. What a smart way God has designed this lubricating fluid precum.
- Acidity of urine is not suitable for sperms. Precum as though washes away and neutralizes this acidity. Precum also helps in neutralizing the acidity of vagina.
- Precum has a role in coagulation of semen.
Names of precum
Precum is also called as pre ejaculatory fluid or pre ejaculate or pre seminal fluid or Cowper’s fluid.
Source of precum
Cowper’s gland (see in the picture above) secrete watery fluid. Bulbo urethral glands (Cowper’s glands), glands of littre release this watery fluid. Precum is lubricant as well as acid neutralizer. Preejaculatory fluid is also called precum or pre ejaculate. This is not semen.
Amount of Precum
Some men may not produce precum. Some men may produce up to 5 ml of precum. Typically the underwear gets a wet patch because of precum.
Pre-cum, HIV/STI and pregnancy
Precum has been found to contain HIV Human Immunodeficiency Virus that causes AIDS Acquired Immuno Deficiency Syndrome.
It was believed that precum also may contain sperms. Hence, it was said that contact of precum with vagina or nearby may cause pregnancy. However, there are some studies that show that precum does not contain sperms. Not only that, but the studies also show that withdrawal method or coitus interruptus of family planning is as effective as condom in preventing pregnancy.
If you have questions you can ask doctor.
