The fluid referred to as semen, which contains the sperm, does not consist of sperm alone. On the contrary, it is made up of a mixture of different fluids. Seminal fluid is a collection of substances secreted from the testicles, the seminal vesicles, the prostate gland and glands linked to the urinary tract. A detailed analysis of this fluid shows that it consists of a great many separate substances, such as citric acid, prostaglandin, flavin, ascorbic acid, ergothioneine, cholesterol, phospholipids, fibrinolysin, zinc, phosphatase acid, phosphase, hyaluronidase and sperm. These fluids exercise different functions, such as containing the sugar necessary for providing energy for the sperm, neutralizing the acids at the entrance of the uterus, and providing a slippery substance for the easy movement of the sperm.
When semen is mentioned in the Qur’an, this fact, which was discovered by modern science, is also referred to, and semen is defined as a mixed fluid:
076.002► إِنَّا خَلَقْنَا الإنْسَانَ مِنْ نُطْفَةٍ أَمْشَاجٍ نَبْتَلِيهِ فَجَعَلْنَاهُ سَمِيعًا بَصِيرًا We created man from a mingled drop to test him, and We made him hearing and seeing. (Qur’an, Al-Insan -76:2)
In other verses, semen is again referred to as a mixture, and it is stressed that man is created from the “extract” of this mixture:
032.007► الَّذِي أَحْسَنَ كُلَّ شَيْءٍ خَلَقَهُ وَبَدَأَ خَلْقَ الإنْسَانِ مِنْ طِينٍ
032.008► ثُمَّ جَعَلَ نَسْلَهُ مِنْ سُلالَةٍ مِنْ مَاءٍ مَهِينٍ He Who has created all things in the best possible way. He commenced the creation of man from clay; then He made his progeny from an extract of discarded fluid. (Qur’an, As-Sajda -32:7-8)
The Arabic word “sulaalah,” translated as “extract,” means the essential or best part of something. By either meaning, it refers to “part of a whole.” This shows that the Qur’an is the word of Allah, Who knows the creation of man to its minute details.
