Sperm are zygote cells that have half the genetic load, which is why when they join the ovum in fertilization, they form the complete genetics of the human.
In turn, the sperm has very efficient mechanisms for obtaining rapid energy, since they consume many ATP molecules when inoculating the ovum during fertilization.
They are formed by with the help of the sertoli cell, which sets the physiological state so that in the human testicle they are formed releasing in the male semen.
