“…Cold stress during sperm cryopreservation leads to decreased sperm quality, and it is one of important concerns in the usage of thawed spermatozoon in ART. The supplementation of freezing and/or thawing media with antioxidant has been assumed to improve the sperm function efficiency (Santonastaso et al, 2021).…”

Sperm cryopreservation as a routine technique in assisted reproductive technique (ART) laboratories has detrimental effects on spermatozoa. Various methods have been introduced to improve it. The aim of this research was to evaluate the effects of L‐proline supplementation in cryopreservation medium on normozoospermic semen samples. A total of 30 semen samples were collected from normozoospermic men. Cryopreservation media were supplemented with different concentrations of L‐proline (0, 1, 2 and 4 mmol/L). The semen samples were cryopreserved. After thawing, sperm parameters and chromatin integrity (aniline blue (AB), toluidine blue (TB), sperm chromatin dispersion test (SCD) and chromomycin A3 (CMA3)), reactive oxygen species (ROS), and total antioxidant capacity (TAC) and malondialdehyde (MDA) levels were evaluated. A total of 4 mmol/L L‐proline significantly improved progressive motility and viability (p < 0.05). MDA and ROS levels significantly diminished in samples were cryopreserved by 4 mmol/L L‐proline supplemented cryopreservation media (p < 0.001). Also, it significantly increased TAC level. Also, chromatin damages (AB, TB and CMA3) significantly improved in samples were cryopreserved by 4 mmol/L L‐proline supplemented cryopreservation media (p < 0.05). The results support that the usage of L‐proline supplemented cryopreservation media to improve sperm quality after cryopreservation.

“…Cur also showed an ability to counteract the H 2 O 2 -induced oxidative damage, particularly at the highest concentration tested (40 µM). Literature data have already shown the protective effects of curcumin against damage induced by mutagenic pollutants such as benzo(a)pyrene and other genotoxic agents, protecting against DNA fragmentation by suppressing ROS production and increasing glutathione peroxidase 4 (GPX4) gene expression [35], which is known to protect cells from DNA-damaging oxidative stress caused by cell membrane peroxidation [36].…”

Oxidative imbalances in the gestational phase are responsible for certain complications during pregnancy and for foetal and neonatal genetic disorders. In this work, using human amniocytes, we aimed to evaluate the protection provided to foetal DNA by two concentrations of antioxidant molecules, α-lipoic acid (LA) and curcumin (Cur), against hydrogen peroxide (H2O2)-induced damage. Genotoxicity tests, performed by the random amplification of polymorphic DNA (RAPD-PCR) technique and TUNEL tests, showed that the lowest concentration of LA-protected cells and DNA from H2O2 insults. However, a greater ability to protect the amniocytes’ DNA against H2O2 was observed following co-treatment with the highest concentration of Cur with H2O2. In fact, a genomic template stability (GTS%) similar to that of the negative control and a statistically significant reduction in the DNA fragmentation index (DFI) were revealed. Moreover, following a combined treatment with both antioxidants and H2O2, no statistical difference from controls was observed, in terms of both induced mutations and DNA breaks. Furthermore, no effect on morphology or cell viability was observed. The results demonstrate the ability of LA and Cur to protect the genetic material of amniocytes against genotoxic insults, suggesting their beneficial effects in pathologies related to oxidative stress.

“…It is probable that the effects observed were the consequence of the combination of taurine and hypotaurine. Others AO could be envisaged [23,52] such as selenium, zinc, vitamins C and E and also curcumin [53] for which beneficial effects have recently been shown during human sperm cryopreservation.…”

Background Although widely used, slow freezing considerably modifies the functions of human spermatozoa. Cryopreservation induces nuclear sperm alterations and cryo-capacitation, reducing the chances of pregnancy. Hypotaurine is naturally present in the male and female genital tracts and has capacitating, osmolytic and anti-oxidant properties. The analysis were performed on surplus semen of men with normal (n = 19) or abnormal (n = 14) sperm parameters. Spermatozoa were selected by density gradient centrifugation before slow freezing. For each sample, these steps were performed in parallel with (“H+” arm) or without (“H-” arm) hypotaurine supplementation. After thawing, we measured total and progressive mobility, vitality, acrosome integrity, markers of capacitation signaling pathway and nuclear quality. For the latter, we focused on sperm chromatin packaging, DNA fragmentation and the presence of vacuoles in the sperm nucleus. Results Post-thaw spermatozoa selected and frozen in the presence of hypotaurine had a higher vitality (+ 16.7%, p < 0.001), progressive and total motility (+ 39.9% and + 21.6% respectively, p < 0.005) than spermatozoa from the control “H-” arm. Hypotaurine also reduced the non-specific phosphorylation of the capacitation protein markers P110 and P80 (p < 0.01), indicating a decrease in cryo-capacitation. Hypotaurine supplementation reduced chromatin decondensation, measured by chromomycin A3 (− 16.1%, p < 0.05), DNA fragmentation (− 18.7%, p < 0.05) and nuclear vacuolization (− 20.8%, p < 0.05). Conclusion Our study is the first to demonstrate beneficial effects of hypotaurine supplementation in preparation and freezing procedures on human spermatozoa sperm fertilization capacity and nucleus quality. Hypotaurine supplementation limited cryo-capacitation, increased the proportion of live and progressively motile spermatozoa and reduces the percentage of spermatozoa showing chromatin decondensation, DNA fragmentation and nuclear vacuolation.
