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.}} | 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.

Naik’s embryology is askew. The original position of the cells destined to develop into spermatogonia (sperm producing cells) is not ventro-medial to the kidneys (where they undoubtedly develop) but in the wall of the yolk sac: | |||
{{Quote||Testes and ovaries are derived from the mesodermal epithelium (mesothelium) lining the posterior abdominal wall, the underlying mesenchyme and the primordial germ cells. | {{Quote|| | ||

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).<ref>[http://web.indstate.edu/thcme/duong/EMBRYOL.html Indiana University; School of Medicine]</ref>|The Developing Human, 6th ed., p. 323, fig. 13-28}} | The primordial germ cells form in the wall of the yolk sac during week 4.

Note that the inferior pole of the kidney lies around ''L3'' (the third lumbar vertebra), thus the embryonic testes must be below ''L3''. The twelth rib does not extend below ''L2''. Since 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. | Note that the inferior pole of the kidney lies around ''L3'' (the third lumbar vertebra), thus the embryonic testes must be below ''L3''.

It also seems disingenuous to interpret a ‘drop emitted, proceeding from between the backbone and the ribs’ to mean the embryonic development of the testes, as the ‘drop emitted’ suggests 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 the peri- and post-pubertal testes do. | |||
Naik’s explanation of the nerve, blood and lymphatic circular from the abdominal aorta is irrelevant and constitutes the logical fallacy of the red herring. This is because verse 85:6 speak about ‘a drop emitted’, commonly taken to mean semen and semen only, as this drop is directly responsible for human reproduction, something which cannot be claimed for nerve signals, blood or lymph. Further, circulation and nerve supply 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. | |||
