Determining fetal sex from semen

تحديد جنس الجنين من المني

Verse reference

أَلَمْ يَكُ نُطْفَةً مِّن مَّنِيٍّ يُمْنَىٰ * ثُمَّ كَانَ عَلَقَةً فَخَلَقَ فَسَوَّىٰ * فَجَعَلَ مِنْهُ الزَّوْجَيْنِ الذَّكَرَ وَالْأُنثَىٰ

القيامة 37-39

Interpretive reading

Sex is determined by the sperm (carrying X or Y chromosomes), not by the egg; this conclusion is supported by evidence from modern genomics.

Stages of Embryo Development

وَلَقَدْ خَلَقْنَا الْإِنسَانَ مِن سُلَالَةٍ مِّن طِينٍ * ثُمَّ جَعَلْنَاهُ نُطْفَةً فِي قَرَارٍ مَّكِينٍ * ثُمَّ خَلَقْنَا النُّطْفَةَ عَلَقَةً فَخَلَقْنَا الْعَلَقَةَ مُضْغَةً فَخَلَقْنَا الْمُضْغَةَ عِظَامًا فَكَسَوْنَا الْعِظَامَ لَحْمًا

The stages: nutfah → ’alaqah (a leech‑like clot that attaches to the uterine wall) → mudghah (a chewed‑like lump) → bones → clothed with flesh. This sequence is sometimes read as corresponding to modern embryology; this is an interpretive reading.

The Embryo in Three Darknesses

يَخْلُقُكُمْ فِي بُطُونِ أُمَّهَاتِكُمْ خَلْقًا مِّن بَعْدِ خَلْقٍ فِي ظُلُمَاتٍ ثَلَاثٍ

The "three darknesses" in the Quran are sometimes read as the abdominal wall, the uterine wall, and the placenta (chorion). This interpretive reading was recognized through modern embryology.

Fingerprints

بَلَىٰ قَادِرِينَ عَلَىٰ أَن نُّسَوِّيَ بَنَانَهُ

The Quranic verse is sometimes read as pointing to the distinctive nature of the fingertips; this is an interpretive reading that notes fingerprints were not recognized as a unique means of identification until the 19th century.
