[Pentoxifylline--an andrologic drug?].

In order to estimate the therapeutic use of pentoxifylline respecting idiopathic oligozoospermia, we undertook biostatistical evaluation of two open studies of different outcome. However, such a procedure turned out to be impossible, because the patients' reactions could not be classified enough under consideration of history, age, hormonal background, and spermiogram. Thus the question of indication for treatment with pentoxifylline in cases of disturbed fertility has to remain still unanswered.
