Does precum contain sperm? This subject has been researched in medical journals and the conclusion is very clear.

In the "Journal of Assisted Reproduction Genetics, 2003 Apr;20(4):157-9. Zukerman asked "Does preejaculatory penile secretion originating from Cowper's gland contain sperm?" "Department of Obstetrics and Gynecology, Rabin Medical Center, Petah Tikva, Israel."

Their conclusion was "Preejaculatory fluid secreted at the tip of the urethra from Cowper's gland during sexual stimulation did not contain sperm and therefore cannot be responsible for pregnancies during coitus interruptus." You can't be more definitive than that.

Precum does not contain sperm UNLESS there was a previous ejaculation, then the sperm comes from semen still in the urethra.

The main reason for failure of the withdrawl method is the inability of guys to admit they didnt pull out in time.
