works outside of our will. This wonderful machine finishes its task by sending what it has absorbed to the blood and tissues of the body. During puberty, food is absorbed and sent to the testes to create reproductive cells in boys, and to the ovaries in girls.

....THE REPRODUCTIVE SYSTEM IN HUMANS
....Allah Almighty says:
...."Then We placed him as (a drop of) sperm in a place of rest, firmly fixed;" (Mumenoon, 13)
....All things in this world have been put into a systematic order by Allah Almighty. In the same way that He created human beings from dust, He begins reproduction in human beings through the fusion of the sperm and egg. However, Allah informs us in the following way that this is not sufficient:
...."Surely We have created man from a small life-germ uniting (itself):" (Insan, 2)
....Allah, Who has created the order that brings the sperm and egg together to create a new life, has created lust, an unseen force, that directs people and animals toward this union. And when the egg in the fallopian tube of the woman has been impregnated by the sperm of the man, the creation of a new life instantly starts in the womb and the fertilized egg becomes known as an embryo.
....Allah Almighty says:
...."Then We made the seed a clot, then We made the clot a lump of flesh, then We made (in) the lump of flesh bones, then We clothed the bones with flesh, then We caused it to grow into another creation." (Mumenoon, 14)
