Effect of the Oral Intake of Astaxanthin on Semen Parameters in Patients with Oligo-Astheno-Teratozoospermia: A Randomized Double-Blind Placebo-Controlled Trial
Oral intake of astaxanthin and semen parameters in infertile patients
Background. Higher concentrations of seminal reactive oxygen species may be related to male infertility. Astaxanthin with high antioxidant activity can have an impact on the prevention and treatment of various health conditions, including cancer. However, efficacy studies on astaxanthin in patients with oligo- with/without astheno- with/without teratozoospermia (O±A±T) have not yet been reported. Our aim was to evaluate the effect of the oral intake of astaxanthin on semen parameters.
Patients and methods. In a randomized double-blind trial, 80 men with O±A±T were allocated to intervention with 16 mg astaxanthin orally daily or placebo. At baseline and after three months basic semen parameters, sperm deoxyribonucleic acid (DNA) fragmentation and mitochondrial membrane potential of spermatozoa and serum follicle-stimulating hormone (FSH) value were measured.
Results. Analysis of the results of 72 patients completing the study (37 in the study group, 35 in the placebo group) did not show any statistically significant change, in astaxanthin group no improvements in total number of spermatozoa, concentration of spermatozoa, total motility of spermatozoa, morphology of spermatozoa, DNA fragmentation and mitochondrial membrane potential of spermatozoa or serum FSH were determined. In the placebo group, statistically significant changes in the total number and concentration of spermatozoa were determined.
Conclusions. The oral intake of astaxanthin did not affect any semen parameters in patients with O±A±T.
