Just felt like bringing em up for those who r new or might have missed......

Quran:86:5:"So let the man consider from what he is created.. 6:He is created from a fluid emitted. 7: proceeding from between the backbone and the rib. 8:Surely He(Allah) is able to bring him back (to life). 9:On the day when hidden thoughts shall be searched out.
Other explaination given by many is also true...... that testes receives it's blood supply from testicular(Gonadal) arteries that originate b/w ribs & backbone on each side of backbone.... & the "fluid emitted" is formed from that blood.
Look for "Gonadal" Artery:-

Wa-alaikum Assalaam
This refers to EMBRYOLOGICAL development of testes(& overies) inside mothers womb:-
A structure called "Intermediate mesoderm" is formed on each sides of vertebral column(spine).
Then it differentiates into 3 parts:-
1>"Pronephros" on each side of spine of NECK(neck region) of developing baby(embryo). It dissolves off & does NOT make any important structure in fully developed human baby.
2>"Mesonephros"(pic) is part of "intermediate mesoderm" between spine & ribs (thoracic region)on each side. It develop lots of tubules(pic) which later form testes. & sperms r formed in these tubules. Then testes migrates(proceeds) downwards from here to it's final place , scrotum. In some premature babies testes r un-descended completely & r found in abdomen & have to b surgically corrected.
3>"Metanephros" is part of "intermediate mesoderm" on each side of abdominal spine of developing baby.It also form tubulus & develop into kidneys. Kidneys r in pelvis of developing baby. Then they ASCEND to reach final position in upper abdomen.
These embryological stages have been discovered in recent past. & Allah's book indicated towards it 1400+ years ago.
Quran:86:5:"So let the man consider from what he is created.. 6:He is created from a fluid emitted. 7: proceeding from between the backbone and the rib. 8:Surely He(Allah) is able to bring him back (to life). 9:On the day when hidden thoughts shall be searched out.
(that is; He can duplicate the same processes of development again)

Right upper rounded ball is testes & Left upper rounded ball is ovary while Grey Mushroom-Like oval masses on lower side are KIDNEYS. Kidneys are formed in pelvis & then ascendLink to abdomen while Testes & ovaries form in Chest Region & then descend to scrotum & pelvis respectively.
[86:5] Now let human but think from what he is created![86:6] He is created from a drop emitted-[86:7] Proceeding from(indicate site of origin of gonads) between the backbone and the ribs:
So Sperm forming cells & eggs are from chest region of developing baby(embryo)

You can see "mesonephros" lying under ribs in picture below:-This mesonephros becomes testes in baby-boy & ovaries in baby-girls:-
