"It is We Who have created you. Why, then, do you not accept the truth? Have you ever considered that [seed] which you emit? Is it you who create it? Or are We the Creator? (Qur'an, 56:57-59)"
Only very few sperms out of 250 million sperms emitted from the male can make it to the ovum. The sperm that will fertilise the egg is the only one out of a thousand sperms that have managed to survive. The fact that man is made not from the entire semen—but only a small part of it—is related in the Qur'an with the expression, "a drop of ejected semen."
The discovery of these facts could only become possible by the technology attained in the 20th century.
Sperm undertake a journey into the woman'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 sperms in. That is, the substance of man is not the whole semen, but only a small part of it.
This is explained in the Surat al-Qiyama as follows: "Does man reckon he will be left uncontrolled [without purpose]? Was he not once a drop of ejected semen? (Qur'an, 75:36-37)"
Before this discovery, many people think that the baby's sex determined by the woman's cells so if the mother cannot give ''a boy" , people will make mother in the wrongside. Actually we found a different information in the Qur'an, where it is stated that masculinity or femininity is created out of "a drop of sperm which has been ejected."
He has created both sexes, male and female from a drop of semen which has been ejected. (Qur'an, 53:45-46)
Was he not a drop of ejaculated sperm, then a blood-clot which He created and shaped, making from it both sexes, male and female? (Qur'an, 75:37-39)
The developing disciplines of genetics and molecular biology have scientifically validated the accuracy of this information given by the Qur'an. It is now understood that sex is determined by the sperm cells from the male, and that the female has no role in this process. In other words, a baby's sex is determined by which chromosome from the male unites with the female's ovum.None of this was known until the discovery of genes in the 20th century. Indeed, in many cultures, it was believed that a baby's sex was determined by the female. That was why women were blamed when they gave birth to girls. [learn more]
