the complexity of the semen and the fact that an infinitely small quantity is required to ensure fertilization. In chapter al-Insaan the Qur’an states:
“Verily, I created humankind from a small quantity of mingled fluids.” Qur’an, 76:2
The Arabic word nutfah has been translated as “small quantity”. It comes from the verb meaning ‘to dribble, to trickle’ and is used to describe what remains in the bottom of a bucket which has been emptied. The verse correctly implies that fertilization is performed by only a very small volume of liquid.
On the other hand, mingled fluids ( amshaaj ) has been understood by early commentators to refer to the mixture of male and female discharges. Modern authors have corrected this view and note that the sperm is made up of various components.
When the Qur’an talks of a fertilizing fluid composed of different components, it also informs us that human progeny will be formed from something extracted from this liquid. This is the meaning of the following verse in chapter as-Sajdah:
“Then He made [ man's ] offspring from the essence of a despised fluid.”
Qur’an, 32:8
The Arabic word translated by the term ‘essence’ is sulaalah which means ‘something extracted, the best part of a thing’. In whatever way it is translated, it refers to part of a whole. Under normal conditions, only one single cell, spermatozoon, out of over 50 million ejaculated by a man during sexual intercourse will actually penetrate the ovule.
