Human Reproduction
Allaah The Almighty Says (what means):
{Let man observe that from which he was formed. He was formed from a flowing fluid. It emerges from between the spine and the upper ribs. Verily He is able to return him.}
(Quran, 86:8)
Scientific Analysis
Seminal fluid is a water-based solution containing a great number of sperm. A single sperm cell, called a spermatozoon, resembles nothing less than a drop of water in the macroscopic world; while on a microscopic level, it is an individual spermatozoon that will inseminate the ovum.
The cellular origins of the testes in men and the ovaries in women are located in the backs of parents when they were fetuses. They gather in a common reproductive organ called the Gonad.
Each of them then exits from an area between the spinal column and the ribcage. The ovaries then migrate to the pelvic region by the womb, while the testes migrate to the scrotum, where the temperature is most suitable, otherwise, it will fails to produce sperm at the time of puberty.
The Miracle
Regarding His Saying: {Let man observe that from which he was formed. He was formed from a flowing fluid. It emerges from between the spine and the upper ribs. Verily He is able to return him.}
(Quran, 86:8)
{Flowing fluid} is a description of semen, as it is a fluid like water due to the plurality of droplets. However, its components flow and move with excitement. This is affirmed in the Arabic usage of the active participle daafiq for {flowing}, indicating its essential movement. All such descriptions are correct when applied to man.
The description in {it emerges from between the spine and the upper ribs} clarifies the point of exit for progeny, just as the point of origin is seen in His Saying:
{When your Lord took from the children of Adam, from their backs, their progeny.}
(Quran, 7:172)
He also Says (what means):
{Your sons who are from your spines.}
(Quran, 4:23)
This was not affirmed by science until many wearisome studies were conducted after the invention of the microscope, the crudest of which was invented in 1590 in the Netherlands.
