In the article “The Human Vomeronasal Organ. Part II: Prenatal Development” (Journal of Anatomy, Vol. 197, Issue 3, pp. 421–436), T. Smith and K. Bhatnagar examined the controversial issue of the human vomeronasal organ, regarding its structure, function, and identity. The following table shows the age of fetuses, in weeks, and length of crown-rump, in millimetres.     

X	10	10	13	13	18	19	19	23	25	28
Y	62	62	105	102	161	166	172	225	232	280
