There is no evidence for repeatedly do so in Qur'an. So It was once for the beginning.
There are Quranic verses which imply that Eve was created from the extra clay Prophet Adam was created from.
The verses are as follows:
1- یا أَیُّهَا النَّاسُ اتَّقُوا رَبَّکُمُ الَّذی خَلَقَکُمْ مِنْ نَفْسٍ واحِدَةٍ وَ خَلَقَ مِنْها زَوْجَها
O mankind, fear your Lord, who created you from one soul and created
from it its mate...(Surat An-Nisā',verse 1)
2- هُوَ الَّذی خَلَقَکُمْ مِنْ نَفْسٍ واحِدَةٍ وَ جَعَلَ مِنْها زَوْجَها لِیَسْکُنَ إِلَیْها
It is He who created you from one soul and created from it its mate
that he might dwell in security with her...(Surat Al-'A`rāf,verse 189)
3- خَلَقَکُمْ مِنْ نَفْسٍ واحِدَةٍ ثُمَّ جَعَلَ مِنْها زَوْجَها
He created you from one soul. Then He made from it its mate...(Surat
Az-Zumar,verse 6)
In addition in Surat An-Nisā',verse 1 Allah said:
يا أَيُّهَا النَّاسُ اتَّقُوا رَبَّکُمُ الَّذي خَلَقَکُمْ مِنْ نَفْسٍ
واحِدَةٍ وَ خَلَقَ مِنْها زَوْجَها وَ بَثَّ مِنْهُما رِجالاً
کَثيراً...
O mankind, fear your Lord, who created you from one soul and created
from it its mate and dispersed from both of them many men and
women...(Surat An-Nisā',verse 1)
So as you see Allah dispersed from both Eve and Adam many men and women which naturally dispersed from them many men and women, too.
It shows that the women (wives) are from the first generation of human being which is Eve and Adam such other men are(Not to be from other men which themselves are from Eve and Adam).
So, It was just once for Eve and Adam.
