The Negative Impact of Varicocele on Basic Semen Parameters, Sperm Nuclear DNA Dispersion and Oxidation-Reduction Potential in Semen.

Since varicocele is so common in infertile men, this study intends to analyse the relationships between varicocele and conventional semen characteristics, sperm nuclear DNA dispersion and oxidation-reduction potential (ORP) in semen. Varicocele-positive and varicocele-negative infertile men (study groups) showed significantly lower standard sperm parameters and higher sperm DNA fragmentation (SDF) and ORP in semen than healthy volunteers and subjects with proven fertility (control groups). A lower proportion of low SDF levels (0-15% SDF) and higher incidence of high SDF levels (>30% SDF), as well as a higher prevalence of high ORP values (>1.37 mV/106 sperm/mL), were found in the study groups vs. the control groups. Moreover, infertile men had significantly lower odds ratios (ORs) for low SDF levels and significantly higher ORs for high SDF levels and high ORP. SDF and ORP were negatively correlated with sperm number, morphology, motility and vitality. Furthermore, a significant positive correlation was found between SDF and ORP. The obtained results suggest that disorders of spermatogenesis may occur in varicocele-related infertility. These abnormalities are manifested not only by reduced standard semen parameters but also by decreased sperm DNA integrity and simultaneously increased oxidative stress in semen.

SARS-CoV-2: diagnostic and design conundrums in the context of male factor infertility.

The question of whether SARS-CoV-2 (severe acute respiratory syndrome-related coronavirus-2 [SARS-CoV-2], leading to the COVID-19 infection) can be harboured in the testes and/or semen is currently unanswered. It is essential to understand the limitations of both antibody and real-time PCR tests in interpreting SARS-CoV-2 data in relation to analyses of semen and testicular tissue without appropriate controls. This article critically analyses the evidence so far on this, and the possible implications. The limitations of diagnostic tests in both sampling and testing methodologies, their validation and their relevance in interpreting data are also highlighted.

Utility and Predictive Value of Human Standard Semen Parameters and Sperm DNA Dispersion for Fertility Potential.

Because the assessment of sperm DNA fragmentation (SDF) plays a key role in male fertility, our study was designed to find the relationships between SDF and standard semen parameters. The receiver operating characteristic (ROC) curve showed that 18% SDF is a prognostic parameter for discriminating between men with normal and abnormal standard semen parameters (n = 667). Men with > 18% SDF had significantly lower quality semen, a higher prevalence of abnormal semen characteristics, and a higher odds ratio for abnormal semen parameters compared to men with ≤ 18% SDF. An ROC analysis provided predictive values for age and semen parameters to distinguish between men with SDF > 18% and men with ≤ 18% SDF. SDF was positively correlated with male age and teratozoospermia index but negatively with sperm concentration, total number of spermatozoa, sperm morphology, progressive motility, and vitality. Our study shows that 18% SDF has a predictive value for distinguishing between men with normal and abnormal semen characteristics. Men with >18% SDF have a higher risk for abnormal semen parameters, while age and obtained semen parameters have a predictive value for SDF. There is a relationship between SDF and conventional sperm characteristics, and thus, SDF can be incorporated into male fertility assessment.

The higher risk for sperm DNA damage in infertile men.

OBJECTIVES: Supplementary assays are needed for determination of relationships between sperm biomarkers and fertility potential. Therefore, our research was designed to determine the extent of sperm DNA fragmentation (SDF) and establish a discriminating threshold of SDF for fertility potential. MATERIAL AND METHODS: Semen characteristics were evaluated according to World Health Organization recommendations, and SDF was assessed by sperm chromatin dispersion test on ejaculated spermatozoa from infertile and healthy normozoospermic men. RESULTS: A higher proportion of SDF was noted in infertile men (median 23.00%) than normozoospermic (median 14.00%). Significantly less subjects (17.03%) with low SDF level (≤ 15%) and more (35.17%) with high SDF level ( > 30%) were found for the infertile group vs the normooospermic (57.90% and 5.26%, respectively). Infertile group had significantly lower odds ratio (OR) for having a low SDF level (OR: 0.1493) and higher OR for having a high SDF level (OR: 9.7627). Receiver operating characteristic analysis [area under curve (AUC) = 0.785] revealed that 20% SDF is predictive value for discriminating between infertile and normozoospermic subjects. SDF was negatively correlated with the sperm number, morphology, progressive motility and vitality but positively with the teratozoospermia index. CONCLUSIONS: Our study demonstrates: (1) a significant difference in the extent of SDF and in the risk for having damaged sperm DNA between infertile and normozoospermic men, (2) > 20% SDF has negative predictive value for fertility potential, (3) coexistence of abnormal standard sperm parameters with sperm chromatin damages. Therefore, SDF should be considered as a highly valuable indicator of male fertility potential.

Long-term effect of thermoablative fractional CO2 laser treatment as a novel approach to urinary incontinence management in women with genitourinary syndrome of menopause.

INTRODUCTION AND HYPOTHESIS: The aim of this study was to evaluate the long-term effect of thermoablative fractional CO2 laser (TACO2L) as an alternative treatment for early stages of stress urinary incontinence (SUI) in postmenopausal women with genitourinary syndrome of menopause. METHODS: A total of 161 postmenopausal patients (age 53.38 ± 5.1 years, range 45-65 years) with a clinical diagnosis of mild SUI were prospectively enrolled in the study. Patients received one treatment with TACO2L every 30-45 days, each treatment comprising four sessions, followed in all patients by a yearly treatment session at 12, 24 and 36 months. SUI was evaluated using the International Continence Society 1-h pad test and the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF) before and after TACO2L treatment. RESULTS: TACO2L treatment was associated with a significant improvement in ICIQ-UI SF scores and 1-h pad weight test at 12 months (both p < 0.001), 24 months (both p < 0.001) and 36 months (both p < 0.001). Improvements were maintained for up to 36 months without the need for any further intervention. The results were confirmed by significant histological changes related to trophic restoration of the vagina, responsible for extrinsic and intrinsic mechanisms involved in urinary continence. CONCLUSIONS: Our results suggest that TACO2L is an efficient and safe novel treatment strategy in patients with mild SUI. Further investigation to confirm the long-term results presented here is still warranted.

Sperm parameters and DNA fragmentation of balanced chromosomal rearrangements carriers.

INTRODUCTION: Somatic chromosomal rearrangements that occur in infertile males are thought to be one of the major genetic factors influencing male infertility. The objective of this retrospective study was to evaluate sperm parameters in a group of patients with balanced translocations. MATERIAL AND METHODS: We analyzed semen of 84 balanced somatic translocation carriers [35 Robertsonian translocation (RT group) and 49 reciprocal translocation (RCT group)] and 57 men with normal karyotype (control group). Semen samples were evaluated for sperm concentration, its motion parameters and vitality, round cell number (CASA) and DNA fragmentation index (TUNEL). Cytogenetic evaluation was also performed for each study participant. RESULTS: Sperm concentrations were lower when comparing the RT group to the control (p < 0.001) and RCT groups (p < 0.05). Occurrence of abnormal sperm concentration was more common among RT carriers (74.3%) than in the other groups (42.9% in RCT group and 28.1% in control group). The sperm progressive motility and vitality in RT carriers (21.53% and 62.17%) were lower than in control group (39.77% and 77.47%, p < 0.001, respectively) and RCT carriers (31.47% and 76.17%, p < 0.001, respectively). The RCT carriers and the control group did not differ in regard to sperm concentration, progressive sperm motility, motility grade D and sperm vitality. There were no significant differences in DNA fragmentation in carriers of both studied structural chro­mosomal rearrangements in comparison to subjects with normal karyotype. CONCLUSIONS: RT carriers had significantly lower semen parameters in comparison to not only the subjects with normal karyotypes but also the RCT carriers.

First Pregnancy, Somatic and Psychological Status of a 4-Year-Old Child Born following Annexin V TESA Sperm Separation.

Introduction Sperm DNA integrity is a crucial paternal factor affecting fertilization and pregnancy rates, as well as embryo development. Case The present case report describes the successful pregnancy after testicular sperm aspiration (TESA) combined with intracytoplasmic sperm injection (ICSI) (TESA-ICSI) in a couple where the male presented high sperm DNA fragmentation. In order to sort damaged sperm presenting DNA fragmentation, magnetic activated cell sorting (MACS) with annexin V microbeads (MACS Miltenyi Biotec, Teterow, Germany) was used. Conclusion The authors present the first description of a successful medical case using TESA-ICSI annexin V sperm sorting. Additionally, a follow-up of the child at the age of 4 years old was done.

Prognostic value of elastography in predicting premature delivery.

OBJECTIVES: The aim of the study was to assess changes in the consistency of the uterine cervix and correlate the obtained results with the risk of premature delivery and time from examination to delivery MATERIAL AND METHODS: Elastographic images of the cervix in a group of 44 patients, admitted to the hospital due to uterine contractions before 37 weeks of gestation, were recorded and analyzed. Elastograms were assessed with the use of Elastography Index (El), a five-step (0-4) color scale, which visualizes tissue hardness by encoding numerical values in specific colors (0-violet/the hardest tissue; 4-red/the softest tissue). Correlation between El for different parts of the uterine cervix was evaluated and analyzed in relation to preterm delivery and time from examination to delivery. RESULTS: Twenty-one patients delivered before term and 23 at term. A strong correlation for El of the internal os and time from examination to delivery (Pearson test, p<0.001), and risk of preterm birth (Mann-Whitney-Wilcoxon test, p<0.001), was noted. We also found a strong correlation between cervical canal length and risk of preterm delivery (Anova test, p=0.001), and time from examination to delivery (Pearson test, p=0.006). CONCLUSIONS: Elastography may offer a chance for an objective assessment of elasticity of the uterine cervix and may become an alternative to vaginal examination and Bishop score. Proper selection of patients with high or low risk of preterm delivery may facilitate good management decisions and, consequently decrease the percentage of immature deliveries, unnecessary medical procedures, and hospitalization.

Use of ovarian reserve parameters for predicting live births in women undergoing in vitro fertilization.

OBJECTIVE: To examine common clinical determinants, including patient age; levels of anti-Müllerian hormone (AMH), inhibin B, and follicle-stimulating hormone (FSH); antral follicle count (AFC); and number of oocytes retrieved, to predict live births in women undergoing in vitro fertilization. STUDY DESIGN: Women undergoing cycles of intracytoplasmic sperm injection (ICSI) for the first time were reviewed retrospectively, and serum levels of AMH, inhibin B, and FSH, as well as AFC (days 1 and 4 of pre-ICSI menstrual period) and patient age were analyzed as determinants of live birth rates. RESULTS: Of the patients studied, 35.71% (891/2495) became pregnant, with live births achieved in 32.20% (806/2495) of cycles initiated and in 46.37% (806/1738) of embryo transfers. Clinical pregnancy rate was 35.71% (891/2495) for cycles initiated and 51.26% (891/2318) for embryo transfers. Univariate analysis revealed that the odds of live birth significantly decreased with increasing age, declining AMH or inhibin B concentrations, and fewer oocytes retrieved. At AMH levels greater than 5.7 ng/ml, the odds of live birth were 3.18 times greater than for AMH levels less than 1.9 ng/ml [95% confidence interval (CI), 1.89-5.43]. Using multivariate logistic regression, only AMH (OR = 1.89; 95% CI, 1.00-3.60; p < 0.05) and AFC (OR = 1.86; 95% CI, 1.02-3.40; p < 0.05) showed statistically significant associations with live birth. Area under the curve for ROC (ROC(AUC)) indicated that AMH (AUC = 0.60) surpassed AFC (AUC = 0.59), number of oocytes retrieved (AUC = 0.59), inhibin B (AUC = 0.55), FSH (ROC(AUC) = 0.54) and chronological age (ROC(AUC) = 0.53) in predicting live birth. CONCLUSIONS: In this assessment of various indices (i.e., age; levels of AMH, inhibin B, and FSH; AFC; and quantity of oocytes retrieved) for predicting live births for IVF patients, AMH, AFC and the quantity of oocytes retrieved constituted the most reliable determinants.

Predictive value of HPV DNA in lymph nodes in surgically treated cervical carcinoma patients--a prospective study.

OBJECTIVE: High-risk types of HPV are etiological factors in cervical cancer. Lymph node involvement in cervical cancer patients reduces 5-year survival rates by 25-60%. However, the influence on survival of HPV DNA positivity in histopathologically negative lymph nodes remains unresolved. METHODS: The study included 116 of 148 patients who underwent Piver type III radical hysterectomy and pelvic lymphadenectomy and who showed HPV DNA positivity in the primary lesion. Lymph node tissues were tested for the presence of HPV DNA, using a PCR technique. RESULTS: We found the presence of HPV DNA sequences in lymph nodes dissected intraoperatively in 81 (69.83%) cases. In analysis, we compared patients from 3 groups: HPV- and metastatic-negative (LN HPV-M-); HPV-positive metastatic-negative (LN HPV+M-); and metastatic-positive (LN M+). We discovered that survival in groups LN M+ and LN HPV+M- did not differ statistically (p=0.37). However, the survival periods in these two groups differed when compared with LN HPV-M- patients (p<0.001). Using Cox's proportional hazards model, we found that the presence of lymph node HPV DNA, and FIGO stage, and primary lesion volume were independent parameters correlating with survival and mortality risk. CONCLUSION: We conclude that the presence of HPV DNA in lymph nodes is an early sign of metastasis and should be treated as such in prognostic outlook and planning the therapeutic strategy.

Optimization of estradiol supplementation during the luteal phase improves the pregnancy rate in women undergoing in vitro fertilization-embryo transfer cycles.

OBJECTIVE: To evaluate the influence of different E2 supplementation doses during the luteal phase on implantation and pregnancy rates in women undergoing intracytoplasmic sperm injection (ICSI) cycles. DESIGN: Prospective, randomized study. SETTING: A private IVF unit. PATIENT(S): One hundred sixty-six women younger than 40 years who were undergoing IVF with long protocol controlled ovarian hyperstimulation (COH). A total of 231 cycles were investigated. Group 1 (P only) included 80 cycles, group 2 (P and 2 mg of E2) included 73 cycles, and group 3 (P and 6 mg of E2) included 78 cycles. INTERVENTION(S): Supplementation in the luteal phase with different doses of E2 (0, 2, or 6 mg/d). MAIN OUTCOME MEASURE(S): Serum E2 and P levels in the late luteal phase, and implantation rate and pregnancy rate (PR) were documented. The data were analyzed with regard to the entire study population and further stratified according to the E2 dose used. RESULT(S): Significantly higher implantation rate and PR were recorded in those who received low dose E2 supplementation compared with no substitution (PR 23.1% vs. 32.8%). The best implantation and pregnancy results were found significantly in the group with high dose E2 supplementation (PR 51.3%). CONCLUSION(S): For women treated with a long GnRH analogue protocol for COH, addition of a high dose of E2 to daily P supplementation significantly improved the IVF-embryo transfer results.
