Abstract
The effect of in-vitro sperm incubation with Pentoxifylline (PTX) and Coenzyme Q10 (CoQ10) in Oligoasthenoteratozoospermia (OAT) patients was evaluated. Semen samples were obtained from men with Normozoospermia and men with OAT. Motile sperm from the two groups were subdivided into four subgroups: (i) without incubation with PTX + CoQ10; (ii) incubation with PTX; (iii) Incubation with CoQ10; and (iv) incubation with a combination of PTX + CoQ10. Then, sperm parameters, chromatin, DNA and membrane integrity, protamine deficiency, apoptosis, mitochondrial activity, sperm chromatin dispersion test (SCD), hypo-osmotic swelling test (HOS), chromomycin A3 (CMA3), Terminal deoxynucleotidyl transferase dUTP nick end labelling (TUNEL), and diaminobenzidine (DAB) assays were evaluated, respectively. Sperm incubated with CoQ10 and a combination of CoQ10 and PTX resulted in a significant increase in the sperm parameters. Also, a significant decrease was noted with a combination of PTX and CoQ10 in normal men. There was a significant difference between CoQ10 treated and CoQ10 + PTX treated groups in comparison with the OAT group in the percentage of the DNA fragmentation, sperm apoptosis, AB+, HOS test + and sperm mitochondrial activity. Incubated sperm with CoQ10, PTX, and in combination with each other can improve sperm parameters in OAT patients.

Abstract
INTRODUCTION Testicular germ cell tumor is the most frequent neoplasia in men of reproductive age, with a 5-year survival rate of 95%. Antineoplastic treatments induce sperm DNA fragmentation, especially within the first year post-therapy. Data in the literature are heterogeneous concerning longer follow-up periods, and the large majority is limited to 2 years. OBJECTIVE To define the timing for the recovery of sperm DNA damage and the proportion of patients with severe DNA damage at 2 and 3 years from the end of therapy. MATERIALS AND METHODS Sperm DNA fragmentation was evaluated in 115 testicular germ cell tumor patients using terminal deoxynucleotidyl transferase dUTP nick end labeling assay coupled with flow cytometry before (T0 ) and 2 (T2 ) and 3 (T3 ) years post-treatment. Patients were divided based on the type of treatment: carboplatin, bleomycin-etoposide-cisplatin, and radiotherapy. For 24 patients, paired sperm DNA fragmentation data were available at all time-points (T0 -T2 -T3 ). Seventy-nine cancer-free, fertile normozoospermic men served as controls. Severe DNA damage was defined as the 95th percentile in controls (sperm DNA fragmentation = 50%). RESULTS Comparing patients versus controls, we observed: (i) no differences at T0 and T3 and (ii) significantly higher sperm DNA fragmentation levels (p < 0.05) at T2 in all treatment groups. Comparing pre- and post-therapy in the 115 patients, the median sperm DNA fragmentation values were higher in all groups at T2 , reaching significance (p < 0.05) only in the carboplatin group. While the median sperm DNA fragmentation values were also higher in the strictly paired cohort at T2 , about 50% of patients returned to baseline. The proportion of severe DNA damage in the entire cohort was 23.4% and 4.8% of patients at T2 and T3 , respectively. DISCUSSION Currently, testicular germ cell tumor patients are advised to wait 2 years post-therapy before seeking natural pregnancy. Our results suggest that this period may not be sufficient for all patients. CONCLUSION The analysis of sperm DNA fragmentation may represent a useful biomarker for pre-conception counseling following cancer treatment.

Antioxidants (Basel) 2023; 12:1145. [PMID: 37371875 DOI: 10.3390/antiox12061145] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2023] [Revised: 05/19/2023] [Accepted: 05/22/2023] [Indexed: 06/29/2023] Open
Abstract
Cancer impairs spermatogenesis, whereas results on sperm DNA integrity are controversial and no data are available about sperm oxidative stress. In cancer patients, we detected sperm DNA fragmentation (sDF) and both viable (ROS production in viable sperm fraction/viable spermatozoa) and total (ROS production in viable sperm fraction/total spermatozoa) oxidative stress. We found that cancer (22.50 (17.00-26.75)%, n = 85) increased sDF with respect to the control groups in both normozoospermic subfertile patients (NSP) (12.75 (8.63-14.88)%, n = 52, p < 0.001) and in healthy donors (HD) (8.50 (7.00-14.00)%, n = 19, p < 0.001). The induction of viable oxidative stress (n = 96) with cancer was even higher: 36.60 (24.05-58.65)% versus 11.10 (8.63-14.90)% in NSP (p < 0.001) and 9.60 (8.00-14.03)% in HD (p < 0.001). Similar, albeit lower, differences were found for total oxidative stress. SDF sharply correlated to viable oxidative stress when we considered all subjects (cancer patients and controls) (r = 0.591, p < 0.001, n = 134), but no correlation was found when only cancer patients were studied (r = 0.200; p > 0.05, n = 63). In conclusion, cancer significantly increases sDF and sperm oxidative stress levels. Additional mechanisms to oxidative attack might be responsible for increased sDF in cancer patients. Because sperm oxidative stress might affect the outcomes of sperm cryopreservation, of cancer treatments and of sperm epigenoma, the detection of oxidative stress could be of help in managing the reproductive issues of cancer patients.

Abstract
We herein summarise the evidence concerning the impact of sperm DNA fragmentation in various clinical infertility scenarios and the advances on sperm DNA fragmentation tests. The collected evidence was used to formulate 41 recommendations. Of these, 13 recommendations concern technical aspects of sperm DNA fragmentation testing, including pre‐analytical information, clinical thresholds and interpretation of results. The remaining 28 recommendations relate to indications for sperm DNA fragmentation testing and clinical management. Clinical scenarios like varicocele, unexplained infertility, idiopathic infertility, recurrent pregnancy loss, intrauterine insemination, in vitro fertilisation/intracytoplasmic sperm injection, fertility counselling for men with infertility risk factors and sperm cryopreservation have been contemplated. The bulk evidence supporting the recommendations has increased in recent years, but it is still of moderate to low quality. This guideline provides clinicians with advice on best practices in sperm DNA fragmentation testing. Also, recommendations are provided on possible management strategies to overcome infertility related to sperm DNA fragmentation, based on the best available evidence. Lastly, we identified gaps in knowledge and opportunities for research and elaborated a list of recommendations to stimulate further investigation.

Cell-Based Methods for Determination of Efficacy for Candidate Therapeutics in the Clinical Management of Cancer. Diseases 2018; 6:diseases6040085.

Abstract
Determination of therapeutic efficacy is a major challenge in developing treatment options for cancer. Prior to in vivo studies, candidate therapeutics are evaluated using cell-based in vitro methods to assess their anti-cancer potential. This review describes the utility and limitations of evaluating therapeutic efficacy using human tumor-derived cell lines. Indicators for therapeutic efficacy using tumor-derived cell lines include cell viability, cell proliferation, colony formation, cytotoxicity, cytostasis, induction of apoptosis, and cell cycle arrest. Cell panel screens, 3D tumor spheroid models, drug-drug/drug-radiation combinatorial analysis, and invasion/migration assays reveal analogous in vitro information. In animal models, cellular assays can assess tumor micro-environment and therapeutic delivery. The utility of tumor-derived cell lines for efficacy determination is manifest in numerous commercially approved drugs that have been applied in clinical management of cancer. Studies reveal most tumor-derived cell lines preserve the genomic signature of the primary tumor source and cell line-based data is highly predictive of subsequent clinical studies. However, cell-based data often disregards natural system components, resulting in cell autonomous outcomes. While 3D cell culture platforms can counter such limitations, they require additional time and cost. Despite the limitations, cell-based methods remain essential in early stages of anti-cancer drug development.

Abstract
Testicular cancer (TC) is one of the most treatable of all malignancies and the management of the quality of life of these patients is increasingly important, especially with regard to their sexuality and fertility. Survivors must overcome anxiety and fears about reduced fertility and possible pregnancy-related risks as well as health effects in offspring. There is thus a growing awareness of the need for reproductive counseling of cancer survivors. Studies found a high level of sperm DNA damage in TC patients in comparison with healthy, fertile controls, but no significant difference between these patients and infertile patients. Sperm DNA alterations due to cancer treatment persist from 2 to 5 years after the end of the treatment and may be influenced by both the type of therapy and the stage of the disease. Population studies reported a slightly reduced overall fertility of TC survivors and a more frequent use of ART than the general population, with a success rate of around 50%. Paternity after a diagnosis of cancer is an important issue and reproductive potential is becoming a major quality of life factor. Sperm chromatin instability associated with genome instability is the most important reproductive side effect related to the malignancy or its treatment. Studies investigating the magnitude of this damage could have a considerable translational importance in the management of cancer patients, as they could identify the time needed for the germ cell line to repair nuclear damage and thus produce gametes with a reduced risk for the offspring.

Abstract
Sperm cryopreservation is widely used by cancer patients undergoing chemo- or radiotherapy. Evidence suggests that IVF outcome with cryopreserved spermatozoa from cancer patients is less successful. To determine whether sperm DNA fragmentation (SDF) is involved in the lower fertilising ability of cryopreserved spermatozoa of cancer patients, SDF was evaluated in thawed spermatozoa from 78 men affected by different cancers and 53 men with non-cancer pathologies. SDF was assessed by the terminal deoxyribonucleotidyl transferase-mediated dUTP–digoxigenin nick end-labelling (TUNEL), propidium iodide (PI), flow cytometry procedure, which allows determination of two different cell populations (PIbrighter and PIdimmer) and thus to determine the percentage of DNA fragmented sperm in both. PIdimmer spermatozoa are totally unviable, whereas PIbrighter spermatozoa with SDF may be motile and morphologically normal, having higher biological relevance in the reproductive process. We found that the proportion of DNA fragmented PIbrighter cells was significantly higher in thawed spermatozoa from cancer than non-cancer patients. Moreover, a positive correlation was found between the degree of DNA fragmentation and sperm motility in the PIbrighter population of spermatozoa from cancer patients that wasn’t seen in non-cancer patients. The results of the present study suggest that higher SDF levels may contribute to the lower IVF success of cryopreserved spermatozoa from cancer patients and that evaluation of SDF could complement genetic counselling as part of the routine management of cancer patients who seek fertility preservation.

Abstract
BACKGROUND We assessed sperm DNA fragmentation index (DFI) in cancer patients before and after treatment to evaluate if sperm DNA integrity is compromised by cancer itself or its treatment. METHODS In a prospective study, DFI was assessed in 127 patients diagnosed with testicular germ cell tumours (TGCT), Hodgkin's lymphoma (HL), non-Hodgkin's lymphoma (NHL) and various malignancies. The severity of cancer and tumour markers at diagnosis was recorded. Follow-up DFI after treatment was available in 52 patients who were mostly less severely affected. RESULTS In patients diagnosed with TGCT, HL and various malignancies, pretreatment DFI levels were not significantly different from that of proven fertile controls, but in patients with NHL an increased DFI was found. An overall significant decrease in post-treatment DFI (13.2% range 5.0-70.5) compared with pretreatment values (17.1% range 5.1-66.6) was found (P = 0.040). In TGCT patients, post-treatment DFI was significantly higher in patients who were treated with radiotherapy (16.9% range 11.5-39.9) compared with that in patients treated with chemotherapy (CT) alone (10.9% range 5.5-39.9) (P = 0.037). In HL patients, the type of treatment or number of CT cycles was not associated with DFI. Overall, post-treatment DFI in cancer patients was not significantly different from that of proven fertile controls. CONCLUSIONS In this study, the presence of cancer does not seem to negatively affect the sperm DNA integrity in TGCT and HL patients; only NHL patients showed increased DFI at the time of diagnosis compared with healthy controls. Our results confirm previous reports that DFI decreases significantly following various anti-cancer treatments. In contrast, radiotherapy in TGCT patients is associated with an increase in DFI compared with CT treatment alone.

Abstract
PURPOSE Report the characteristics of cryopreserved semen from a cohort of male cancer patients, attitudes towards cryopreservation and outcomes of semen samples based on a 12-year cryopreservation program. MATERIAL AND METHODS Data from 98 male cancer patients whose sperm samples were banked were evaluated. Demographic parameters, semen characteristics, destination of sperm banked samples and questionnaires answered by the patients regarding cryopreservation time were evaluated. RESULTS The cancer diagnoses were testicle (56.1%), prostate (15.3%), Hodgkin's lymphomas (9.2%), non-Hodgkin's lymphomas (7.1%), leukemia (3.1%) and other malignancies (9.2%). The patients with testicular cancer presented lower sperm concentration (p < 0.001); however, there were no differences with the percentage of normozoospermic patients among cancer type groups (p = 0.185). A shorter time between cancer diagnosis and sperm banking was observed for testicular and prostate cancer patients (p < 0.001). Most of the patients (89.5%) favored sperm banking as a fertility preservation method. CONCLUSIONS Although less than 20% of banked sperm samples were disposed of, the majority of patients related sperm banking with safe for fertility preservation. Our results show that all male cancer patients of reproductive age facing cancer treatment could be offered sperm banking.
