The testicles

The testicles have two functions:

  • constant production of spermatozoa from puberty until death.
  • production of male hormone called testosterone.

From each testicle the vas deferens carry the spermatozoa to the penis.

The penis

Allows the passage of urine and sperm. With sexual excitement, it becomes rigid. This erection is caused by a flow of blood and it permits the penetration of the penis into the vagina.

The sperm

The sperm is constituted of spermatozoa and a liquid produced by the prostate and the seminal vesicles. Ejaculation is when sperm spurts out of the penis.

Important !

During erection and before ejaculation the penis discharges a liquid that may contain spermatozoa. Withdrawing before ejaculation will therefore not keep you from getting pregnant. For the same reason, if you use condoms, they must be put on before any contact between the vulva and the penis.
