Seminal plasma isoenzyme LDH X in infertile men

The seminal plasma isoenzyme LDH X and hormonal profile were determined on 55 samples from patients with eigher azoo- or oligozoospermia. The correlation found between the value fo LDH X and the gonadotropins can be used as an indicator of germ cell differentiation. Surprisingly high values of LDH X which were found in patients with severe oligozoospermia could indicate that the patients have normal spermatogenesis and possibly may respond to hormonal therapy.
