The association of a probiotic with a prebiotic (Flortec, Bracco) to improve the quality/quantity of spermatozoa in infertile patients with idiopathic oligoasthenoteratospermia: a pilot study

Maretti, C., Cavallini, G.·2017·Andrology

Abstract

Summary: The hypothesis that the assumption of a probiotic associated with a prebiotic (Flortec, Bracco; one sachet contains: Lactobacillus paracasei B21060 5 × 10 9 cells + arabinogalctan 1243 mg + oligo‐fructosaccharides 700 mg + l ‐glutamine 500 mg) could improve the quality and quantity of spermatozoa in idiopathic oligoasthenoteratospermia ( iAOT ) patients to a larger extent than a control substance (starch) was tested. Forty‐one patients with no chromosomal aberrations were randomized into two groups: 20 received Flortec, one sachet per day for 6 months, whereas 21 received the control substance. The following data were collected: clinical history, scrotal Doppler scans, Y microdeletion, karyotype and cystic fibrosis screens, follicle‐stimulating hormone ( FSH ), luteinizing hormone ( LH ), estradiol (E2), testosterone (T), and prolactin ( PRL ) levels, and two semen analyses. Both the Flortec and the starch groups underwent two semen analyses and one FSH , LH , T, E2, and PRL measurement in the blood, at the beginning of the study, and after 6 months. The comparisons were carried out using a non‐parametric (Wilcoxon signed rank) test. The side effects were assessed and compared using the chi‐squared test. Group 1 (Flortec) had their sperm count improved: volume of the ejaculate (median from 2.4 to 3.1 mL; p < 0.01), sperm concentration (median: from 15.2 × 10 6 /mL to 28.3 × 10 6 /39 mL; p < 0.01), progressive motility (median: from 16.2 to 42.0%; p < 0.01), and the percentage of typical forms (median: from 7 to 16.3%; p < 0.01); in addition, their FSH , LH , and T levels improved ( p < 0.01), while those of E2 and PRL did not. Group 2 (control substance) had no modification in 42 of the parameters studied. There were no side effects in either group. These data showed that Flortec constitutes a safe therapy for improving the volume of the ejaculate and the quality/quantity of spermatozoa in iOAT patients.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In another pilot study, a probiotic and prebiotic supplement over 6 months in infertile male patients improved gonadal pathway function including increased FSH, LH, and testosterone compared to control.

    “However, another pilot study supplementing a probiotic and prebiotic (L. paracasei B21060 5 × 109 cells + arabinogalactan 1243 mg + fructooligosaccharides 700 mg + L-glutamine 500 mg) over 6 months in infertile male patients improved gonadal pathway function including increased follicle stimulating hormone, luteinizing hormone, and testosterone levels compared to a control group [256].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
