    The female reproductive system likewise contains two main divisions: the external genitalia (the vulva) and the internal genitalia. The ovum meets with the sperm cell : a sperm may penetrate and merge with the egg, fertilizing it with the help of certain hydrolytic enzymes present in the acrosome.

    The main male sex organs are the penis and the scrotum, which contains the testicles that produce semen and sperm, which, as part of sexual intercourse, fertilize an ovum in the female's body; the fertilized ovum develops into a fetus, which is later born as an infant.

    These cells then induce the production and organisation of cells making up the testicular cords. [2] These cords will eventually become the testes, which in turn produce hormones, in particular testosterone. [8] These hormones drive the formation of the other male sex characteristics, and induce testicular descent out of the abdomen. [4]

    en.wikipedia.org/wiki/Sperm

    Sperm cells cannot divide and have a limited lifespan, but after fusion with egg cells during fertilization, a new organism begins developing, starting as a totipotent zygote. The human sperm cell is haploid, so that its 23 chromosomes can join the 23 chromosomes of the female egg to form a diploid cell with 46 paired chromosomes.

    The same perfect vs. lesser relationship is present between male and female reproductive fluids as in Galen's model as male and female genitalia.
