A few words of thanks would be greatly appreciated.

Sperm - Definition


Sperm is a whitish biological fluid that has a viscous consistency and contains male reproductive cells called spermatozoa. This fluid is composed of spermatozoa, secreted by the testicles, as well as seminal fluid, produced by the seminal vesicles, and prostatic fluid, produced by the prostate. All these components, along with other fluids in smaller quantities, together create a fluid environment through which the spermatozoa can travel, moving by using flagellate, which is a kind of tail located at the end of the spermatozoon enabling them to access the oocyte in the female reproductive zone and commence the process of fertilization.
