A Drop of Semen and Reproduction System

Sperm undertake a journey into the mother’s body until they reach the ovum.

Only a thousand out of 250 million sperm succeed in reaching the ovum.

At the end of this five-minute race, the ovum, half the size of a grain of salt, will let only one of the sperm in. However, this finding that was determined in our own day reveals something that was previously unknown. That is, the substance of man is not the whole semen, but only a small part of it.

this is explained in the Qur’an as follows:

Does man reckon he will be left uncontrolled [without purpose]? Was he not once a drop of ejected semen? (Surat al-Qiyama: 36-37)

As close inspection shows, we are informed in the Qur’an that man is made not from the entire semen, but only a small part of it. This is also what modern science says.
