Abstract
Background The use of flow cytometry (FC) to evaluate sperm DNA fragmentation via deoxynucleotidyl transferase terminal fluorescein dUTP nick-end labeling (TUNEL) has shown inconsistencies compared with conventional fluorescent microscopic analyses. It has been hypothesized that the observed discrepancies could be attributed to the presence of apoptotic bodies that can be labeled with merocyanine 540, the so-called M540 bodies. In order to verify this hypothesis and determine the accuracy of our in-house FC-assisted evaluation of spermatozoa parameters, we used FC to evaluate both the fragmentation of sperm DNA using the TUNEL assay and the oxidation of sperm DNA using the 8-OHdG assay on semen samples with or without M540 bodies. Results We show that the presence of M540 bodies lead to underestimation of both the level of sperm DNA fragmentation and sperm DNA oxidation when using FC assisted detection systems. We also observed that this situation is particularly pertinent in semen samples classified as abnormal with respect to the routine WHO semen evaluation as they appear to contain more M540 bodies than normal samples. Conclusions We conclude that M540 bodies interfere with both FC-conducted assays designed to evaluate sperm nuclear/DNA integrity. Exclusion of these contaminants in unprepared semen samples should be performed in order to correctly appreciate the true level of sperm DNA/nuclear damage which is known to be a critical male factor for reproductive success.

Cannabis consumption might exert deleterious effects on sperm nuclear quality in infertile men. Reprod Biomed Online 2019; 40:270-280.

Abstract
RESEARCH QUESTION Can cannabis consumption alter sperm nuclear integrity in infertile men? DESIGN A retrospective cross-sectional study conducted between July 2003 and December 2013, which included 54 men who consulted for male-factor infertility. Twenty-seven infertile men who were regular cannabis users were matched to 27 infertile men who were cannabis non-users. To complement the conventional semen parameter and plasma hormone level assessments, sperm nuclear alterations were explored using fluorescence in-situ hybridization to assess numerical chromosomal abnormalities, terminal deoxynucleotidyl transferase-mediated dUTP nick-end labelling to investigate DNA fragmentation, aniline blue staining to examine chromatin condensation and a motile sperm organelle morphology examination to detect vacuoles in sperm heads. RESULTS The rates of sperm aneuploidy (P = 0.0044), diploidy (P = 0.037), total chromosome abnormalities (P = 0.0027) and DNA fragmentation (P = 0.027) were significantly higher in cannabis users than in non-cannabis users. CONCLUSIONS Cannabis consumption might have deleterious effects on sperm nuclear quality in infertile men by increasing numerical chromosome abnormalities and DNA fragmentation. Cannabis consumption induces these detrimental effects on the progression of spermatogenesis from meiotic stages to spermiogenesis and potentially on post-testicular sperm maturation in infertile men. Any potential findings, however, need to be validated with larger sample size, and our data are only exploratory findings.
