Objective: Evaluate the impacts of rifampicin on certain sperm function parameters and to determine whether rifampicin has an impact on chromatin quality or sperm DNA integrity. Materials and Methods: Forty two male adult rats were subjected to this study. The entire rats were subjected to random division into six groups; four rifampicin- treated groups and two control groups. Rifampicin- treated groups were treated with a dose of either (27mg/kg/day) or (54mg/kg/day) and for each treatment dose, the treatment persists for either 14 days or 28 days. Certain parameters of sperm function including sperm concentration and sperm motility were assessed. Furthermore, analysis of sperm DNA integrity and chromatin quality were also studied. Results: No significant changes related to sperm concentration were observed when rifampicin was given in different doses and different durations. A significant change in sperm motility were recorded only when rifampicin was given in high dose for 28 days and there was a significant reduction in sperm progressive and total motility. Rifampicin showed a significant increase in sperm DNA staining capability when the dose and duration was increased. Administration of rifampicin in high dosage for 28 days represented in larger adverse impact on structure of sperm chromatin. Conclusion: Rifampicin could negatively affect male fertility potential in rats mainly through affecting the quality of sperm chromatin structure.

SummarySperm DNA fragmentation is referred to as one of the main causes of male infertility. Failures in the protamination process, apoptosis and action of reactive oxygen species (ROS) are considered the most important causes of DNA fragmentation. Action of ROS or changes in sperm protamination would increase the susceptibility of sperm DNA to fragmentation. Routine semen analysis is unable to estimate sperm chromatin damage. Sperm DNA integrity influences sperm functional capability, therefore tests that measure sperm DNA fragmentation are important to assess fertility disorders. Actually, there is a considerable number of methods for assessing sperm DNA fragmentation and chromatin integrity, sperm chromatin stability assay (SCSA modified), sperm chromatin dispersion (SCD), comet assay, transferase dUTP nick end labelling (TUNEL); and protamine evaluation in sperm chromatin assay, such as toluidine blue, CMA3, protamine expression and evaluation of cysteine radicals. This review aims to describe the main causes of sperm DNA fragmentation and the tests commonly used to evaluate sperm DNA fragmentation.

Background: Coronavirus disease 2019 (COVID-19) pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may lead to the infertility of men. Objectives: This study aimed to investigate the impact of COVID-19 infection on sperm parameters and reproductive hormones in fertile men. Methods: A total of 100 males were selected and divided into two groups: (1) patients in convalescence (patients suffering from COVID-19 infection in pharyngeal swab in accordance with reverse-transcription polymerase chain reaction [RT-PCR] or antibodies); (2) negative control group (without antibodies). Semen and blood samples were gathered from all subjects. In the native semen, immunoglobulin (Ig) M and IgG antibodies in the blood were confirmed, and COVID-19 was detected via RT-PCR. To this end, based on the World Health Organization (WHO) guidelines, semen analysis, total antioxidant capacity (TAC), and sperm DNA integrity were assessed. Results: Results demonstrated that sperm concentration, motility, sperm viability, and TAC significantly reduced in fertile males with virus infection. In comparison with the control group, sperm DNA integrity was significantly increased (P < 0.05). Data indicated that the semen volume was not significantly correlated with COVID-19, and there was a significantly negative correlation between sperm concentration, sperm total motility, sperm vitality, sperm normal forms, and TAC with COVID-19. Sperm DNA fragmentation index had a significant and positive correlation with COVID-19 (P < 0.05). In addition, reproductive hormones significantly reduced in fertile males with COVID-19 infection (P < 0.05). Conclusions: COVID-19 infection has a negative influence on sperm parameters and reproductive hormones in fertile males.

For conception and the development of healthy embryos, sperm DNA integrity is crucial. According to a growing body of studies, there is a strong correlation between sperm DNA damage and male infertility. Among the new medicines being developed in the medical field, the application of Platelet Rich Plasma (PRP) in human reproduction has yet to be examined. A total of 100 semen samples were used in the current experimental investigation. From November 2020 to June 2021, the research was conducted at the High Institute for Infertility Diagnosis and Assisted Reproductive Technologies. Masturbation was used to get an ejaculated semen sample. After semen analysis, the samples were separated into two equal parts, one without autologous PRP and the other with 2% autologous PRP, with the DNA fragmentation assessed using the Sperm Chromatin Dispersion Test. There was highly significant reduction in DNA fragmentation index (p < 0.001). The mean sperm DNA integrity was reduced after adding PRP (33.85±16.73 vs 38.55±16.64), Mean (± SE). PRP has been shown to improve human sperm DNA integrity.

The Impact

Biological samples, including cryopreserved sperm, are routinely shipped using air transportation, in dry shippers that are x-rayed along with routine baggage. Accordingly, it is important to demonstrate that there are no potential risks associated with semen transport. The goal of this study was to investigate the impact of airport radiation used for a) checked luggage and b) carry-on luggage on bovine sperm DNA integrity, fertilizing ability, and embryo development. Frozen domestic bull sperm collected from known fertile bulls (n = 9) and stored in a dry shipper (–196°C) were x-rayed 0, 1, 2, and 3 times as a) checked luggage and b) carry-on luggage. Duplicate straws were thawed and assessed for DNA damage using the sperm chromatin structure assay (SCSA®, SCSA Diagnostics, Brookings, SD) and fertilization and embryo development by in vitro fertilization. The SCSA® parameters are the mean and SD of the DNA fragmentation index (mean DFI and SD DFI). Multiple x-rays did not significantly (P > 0.05) affect sperm chromatin heterogeneity assessed by SCSA® and no differences were observed in the mean, SD, and DFI for any of the sperm treatments. No differences (P > 0.05) were seen in embryo cleavage or blastocyst development rates (expressed as percentage of oocytes becoming blastocysts or percentage of cleaved embryos becoming blastocysts) for sperm x-rayed 0, 1, 2, or 3 times using either checked or carry-on luggage doses. The percentage of oocytes developing to the blastocyst stage was 13.8, 11.5, 12.8, and 9.0% (SEM = 2.3%) for sperm exposed to the checked luggage dose 0, 1, 2, and 3 times. The percentage of oocytes developing to the blastocyst stage was 13.0, 12.8, 14.0, and 13.5% (SEM = 3.5%) for sperm exposed to the carry-on luggage dose 0, 1, 2, and 3 times. As future x-ray machines are planned that deliver greater doses of radiation to scan large quantities of baggage with a single scan, it is important that continued monitoring of shipped sperm is performed. The authors are grateful to Lara Metrione, Brian Delauter, and the TSA staff at Jacksonville Airport for assistance with this study.

Significant Difference

Sperm chromatin fragmentation may be caused by a number of factors, the most significant of which is reactive oxygen species. However, little is known about the effect of sperm oxidative stress (OS) on DNA integrity, fertilization, and embryonic development in cattle. Therefore, the goal of this study was to evaluate the influence of sperm OS susceptibility on the DNA fragmentation rate and in vitro embryo production (IVP) in a population of bulls. Groups of cryopreserved sperm samples were divided into four groups, based on their susceptibility to OS (G1, low OS; G2, average OS; G3, high OS; and G4, highest OS). Our results demonstrated that the sperm DNA integrity was compromised in response to increased OS susceptibility. Furthermore, semen samples with lower susceptibility to OS were also less susceptible to DNA damage (G1, 4.06%; G2, 6.09%; G3, 6.19%; and G4, 6.20%). In addition, embryo IVP provided evidence that the embryo cleavage rate decreased as the OS increased (G1, 70.18%; G2, 62.24%; G3, 55.85%; and G4, 50.93%), but no significant difference in the blastocyst rate or the number of blastomeres was observed among the groups. The groups with greater sensitivity to OS were also associated with a greater percentage of apoptotic cells (G1, 2.6%; G2, 2.76%; G3, 5.59%; and G4, 4.49%). In conclusion, we demonstrated that an increased susceptibility to OS compromises sperm DNA integrity and consequently reduces embryo quality.

There is no solid conclusion on the conventional sperm parameters in association with alcohol consumption, evaluation of sperm DNA integrity thus become a more reliable parameter. Hereby, this literature search was performed to summarize alcohol consumption on the sperm DNA integrity. A computerized database search was done through MEDLINE via Ovid (since 1946 until August 2017) and Cochrane was used. The following set of keywords: ‘alcohol consumption OR alcohol intake OR alcohol diet OR drinking alcohol OR ethanol diet’ AND ‘sperm DNA OR sperm chromatin OR sperm genome OR sperm histone OR sperm protamine’ were utilised. 24 articles were retrieved where only five studies conform to the inclusion criteria All studies demonstrated a negative effect of alcohol consumption on sperm DNA integrity, regardless of various range of alcohol doses and duration of alcohol consumption. Out of five studies reviewed, four studies were using a different approach to measure the sperm DNA damage. Hereby, this review identified a need to use a single approach of DNA damage test by having various method of alcohol administration and/or vice versa so that the extension of sperm DNA damage to alcohol consumption will have a better conclusion. On the same note, a few studies have reported the reversibility on conventional semen parameters, none has been done on the sperm DNA damage upon alcohol withdrawal. Therefore, the role of alcohol withdrawal on the reversibility of sperm DNA damage needs to be as well investigated further.
