Comparison of the Level of Vitamins A, D and E of Plasma Seminal of Azoospermia and Normozoospermia.

<b>Background and

Objective

</b> Biological exploration of male infertility is important for its treatment. Seminal plasma, by its composition, presents numerous molecules that can be exploited in the investigation of new sperm biomarkers. The evaluation of new biomarkers of azoosperm seminal plasma aims to identify vitamins A, D and E which can serve as discriminating biochemical markers in the exploration of azoospermia. <b>Materials and

Methods

</b> Thirty normozoospermic and 30 azoospermic sperm samples were collected by masturbation after three days of sexual abstinence from consulting patients at the Pasteur Institute of Côte d'Ivoire. After centrifugation of the sperm, the seminal plasma was collected and were analyzed for vitamin A, D and E. After extracting the vitamins from the seminal plasma, they were quantified using high-performance liquid chromatography. <b>

Results

</b> The concentration of vitamin A in seminal plasma from normal samples was 1.66±1.81 and 0.28±0.52 mg/L in pathological samples. The average vitamin D concentration in seminal plasma of normospermia was 0.27±0.40 and 0.08±0.12 mg/L in seminal plasma of azoospermia. For vitamin E, the results obtained show an average concentration of 2.56±3.58 mg/L in normal ejaculate and 0.33±0.51 mg/L in pathological ejaculate. Only vitamins A and E showed a significant difference in the two categories of sperms. <b>

Conclusion

</b> The determination of the concentration of vitamins A, D and E in seminal plasma showed that only vitamins A and E can serve as a biomarker for the differentiation of normozoospermic and azoospermic sperm.
