In embryonic stages, the reproductive organs of the male and female, i.e. the testicles and the ovaries, begin their development near the kidney between the spinal column and the eleventh and twelfth ribs. Later they descend; the female gonads (ovaries) stop in the pelvis while the male gonads (testicles) continue their descent before birth to reach the scrotum through the inguinal canal.

Even the lymphatic drainage and the venous return goes to the same area.}}Critics argue that Zakir Naik incorrectly present the biology of the phenomenon he describes above. The original position of the cells, they note, are destined to develop into spermatogonia (sperm producing cells) and is not ventro-medial to the kidneys (where these cells develop) but the wall of the yolk sac:{{Quote|{{cite web|url= http://web.indstate.edu/thcme/duong/EMBRYOL.html|title= Urogenital system embryology|publisher= Indiana University School of Medicine|author= Taihung Duong, Ph.D.|date= accessed February 9, 2014|archiveurl= http://www.webcitation.org/query?url=http%3A%2F%2Fweb.indstate.edu%2Fthcme%2Fduong%2FEMBRYOL.html&date=2014-02-09|deadurl=no}}|Testes and ovaries are derived from the mesodermal epithelium (mesothelium) lining the posterior abdominal wall, the underlying mesenchyme and the primordial germ cells.  
In embryonic stages, the reproductive organs of the male and female, i.e. the testicles and the ovaries, begin their development near the kidney between the spinal column and the eleventh and twelfth ribs. Later they descend; the female gonads (ovaries) stop in the pelvis while the male gonads (testicles) continue their descent before birth to reach the scrotum through the inguinal canal. Even in the adult after the descent of the reproductive organ, these organs receive their nerve supply and blood supply from the Abdominal Aorta, which is in the area between the backbone (spinal column) and the ribs. Even the lymphatic drainage and the venous return goes to the same area.}}
 
Critics argue that Zakir Naik makes a number of errors in his claims here. Firstly, {{Quran|8|6}} does not mention a "drop emitted" but rather a water (i.e. fluid) ejected (māin dāfiqin), which was always understood to mean semen, and in the next verse is said to come forth from between the backbone and ribs.
 
Secondly, his interpretation of the verses to mean the embryonic development of the testes is misleading, as the verse implies a fully developed and functional reproductive system, rather than an embryonic structure. Embryonic testes do not emit, ejaculate, gush forth, pour forth, spurt or ejaculate any substance; only peri- and post-pubertal testes and associated glands do.
 
Naik’s explanation of the nerve, blood and lymphatic circular from the abdominal aorta is not relevant to the phenomenon being discussed. Semen is directly responsible for human reproduction, something which cannot be claimed for nerve signals, blood or lymph, or countless other anatomical features enabling a sexually active being. Circulation and nerve supply also do not correlate with embryonic origin. For example, the blood supply, lymphatics and nerve supply of the lower limbs originate in the abdomen and pelvis. This does not mean the lower limbs embryonically originated in the abdomen and pelvis.
 
Finally, critics note that Naik incorrectly presents the biology and location of the phenomenon he describes in a number of ways. The original position of the cells, which are destined to develop into spermatogonia (sperm producing cells) are not ventro-medial to the kidneys (where these cells develop) but the wall of the yolk sac:{{Quote|{{cite web|url= http://web.indstate.edu/thcme/duong/EMBRYOL.html|title= Urogenital system embryology|publisher= Indiana University School of Medicine|author= Taihung Duong, Ph.D.|date= accessed February 9, 2014|archiveurl= http://www.webcitation.org/query?url=http%3A%2F%2Fweb.indstate.edu%2Fthcme%2Fduong%2FEMBRYOL.html&date=2014-02-09|deadurl=no}}|Testes and ovaries are derived from the mesodermal epithelium (mesothelium) lining the posterior abdominal wall, the underlying mesenchyme and the primordial germ cells.  


The primordial germ cells form in the wall of the yolk sac during week 4. They later migrate into the developing gonads at week 6 and differentiate into the definitive germ cells (oogonia / spermatogonia).}}The full argument of the critics runs as follows. If Naik’s assertion that the verse refers to the embryonic testes is accepted, it is not evident whether the gonads are located where he claims, i.e. between the spinal column and the eleventh and twelfth ribs. A cross-sectional diagram of the human embryo shows the gonads at or around the level of the placenta.<center>[[File:Gondev154.gif|alt=|thumb]]</center>Consequently, it cannot be said that the embryonic testes is located between the spinal column and the eleventh and twelfth ribs as the gonadal or genital ridge (precursor of the gonads) is generally held to lie medial to the lower part of the mesonephros, while the adult kidney actually develops from the metanephros.

Line 105: Line 113:
Additionally, the inferior pole of the kidney lies around ''L3'' (the third lumbar vertebra), such that the embryonic testes must be below ''L3''. The twelfth rib does not extend below ''L2''. And because the testes are ''below'' the kidneys, there is no possibility that the testes were ever between the ribs and the backbone either in the embryonic or the adult (as with cryptorchidism) stage.

Moreover, the interpretation of a ‘drop emitted, proceeding from between the backbone and the ribs’ to mean the embryonic development of the testes is misleading, as the ‘drop emitted’ implies a fully developed and functional testes, rather than an embryonic structure. Embryonic testes do not emit, ejaculate, gush forth, pour forth, spurt or ejaculate any substance; only peri- and post-pubertal testes do.
Naik’s explanation of the nerve, blood and lymphatic circular from the abdominal aorta is not relevant to the phenomenon being discussed. {{Quran|85|6}} speaks about ‘a drop emitted’, commonly taken to mean semen, as this drop is directly responsible for human reproduction, something which cannot be claimed for nerve signals, blood or lymph. Circulation and nerve supply also do not correlate with embryonic origin. For example, the blood supply, lymphatics and nerve supply of the lower limbs originate in the abdomen and pelvis. This does not mean the lower limbs embryonically originated in the abdomen and pelvis.
