Their concentration is about 200 million per ejaculation, but only a few hundred go from the cervix to the fallopian tube where the egg is located. , passing through the uterus.

The pre-seminal fluid

Minimal secretion that precedes ejaculation, the pre-seminal fluid is emitted by small glands (Cooper's glands) which secrete it into the urethra canal, under the influence of sexual desire.
