Absence of correlation between the levels of ATP and other seminal compounds in semen and the results of human in-vitro fertilization.

As part of an in-vitro fertilization programme (IVF), semen levels of adenosine triphosphate, fructose, citrate, zinc, free L-carnitine and glycerophosphocholine were measured in 178 men. None of these substances appeared to have any predictive value with regard to the fertilizing potential of the semen during IVF.
