Ubiquinol effect on sperm parameters in subfertile men who have astheno-teratozoospermia with normal sperm...

Considering all the couples willing and trying to get pregnant, the incidence of infertility is 15% of which approximately half of the cases are due to the male factors.

The aim of this study was the investigation of the effects of ubiquinol, reduced form of coenzyme Q10 (Co-Q10), an empiric treatment modality, on sperm parameters in idiopathic subfertility.

In this retrospective study, 62 patients who had received 100 mg ubiquinol twice a day for six months due to idiopathic infertility since January 2012 to January 2013 were included. Only infertile patients with astheno-teratozoospermia without any identified etiology and with a spermatozoa concentration of greater than 13 × 10(6)/mL were included.

The increase in mean values of concentration after the ubiquinol treatment was not statistically significant (P value = 0.065). However, the changes in morphology and motility (fast progressive [a] and a + slow progressive [b]) were statistically significant (P < 0.00).

The weakness of the literature with regard to coenzyme Q10 is about its effects in patients with severely diminished sperm densities and the physiologic steps of morphologic improvements.
