Research question: What is the psychological impact of the COVID-19 pandemic on infertility patients?Design: An anonymous cross-sectional online survey was sent to patients who attended a large university-affiliated infertility practice in the USA between 1 January 2019 and 1 April 2020. At three different time-points respondents were asked to note their top three stressors, from a list of 10 commonly reported life stressors. Results:The questionnaire was sent to 10,481 patients, with 3604 responses (response rate 34%) received. A total of 2202 non-pregnant female respondents were included in the final analysis. One-third of respondents had a prior diagnosis of an anxiety disorder, and 11% reported taking anxiolytic medications; over one-quarter had a prior diagnosis of a depressive disorder and 11% reported taking antidepressant medications. At all three time-points, infertility was noted to be the most frequent top stressor. Coronavirus was noted to be the third most common stressor among the respondents in early March but, at the time of writing, is similar to that of infertility (63% and 66%, respectively). A total of 6% of patients stated that infertility treatment, including IVF, should not be offered during the COVID-19 pandemic. Conclusion:Despite the unprecedented global pandemic of COVID-19, causing economic and societal uncertainty, the stress of infertility remains significant and is comparable a stressor to the pandemic itself.
STUDY QUESTION What is the relationship between sperm DNA fragmentation and oxidative stress (OS) with increasing male age? SUMMARY ANSWER Sperm DNA fragmentation increases with age and is likely related to both defective spermatogenesis and increasing OS levels. WHAT IS KNOWN ALREADY Sperm quality declines with age. The presence of DNA damage in a high fraction of spermatozoa from a raw semen sample is associated with lower male fertility in natural conception and intrauterine insemination. STUDY DESIGN, SIZE, DURATION A retrospective cohort study of 16 945 semen samples analysed at a single reference laboratory between January 2010 and December 2018. PARTICIPANTS/MATERIALS, SETTING, METHODS All males were undergoing an infertility evaluation. The cohort was divided into seven age categories: <30, 30–34, 35–39, 40–44, 45–49, 50 to <54 and ≥55 years. The mean age was 37.6 years (SD 6.8). Sperm DNA fragmentation index (DFI) and high DNA stainability (HDS) were calculated using flow cytometry. OS levels were measured using the oxidative stress adducts (OSA) test, by spectrophotometry. ANOVA with weighted polynomial contrast analysis was used to evaluate trends for DFI, OSA and HDS values across age categories. MAIN RESULTS AND THE ROLE OF CHANCE Mean DFI significantly increased across all age groups (Ptrend < 0.001). OSA was lowest in patients <30 years old (mean 3.6, SD 1.0) and also increased as age increased (Ptrend < 0.001). There was a statistically significant difference between age groups for each of the three parameters (P < 0.001). There was a significant linear trend for DFI, OSA and HDS across the seven age categories (P < 0.001). Among patients with high DFI, there was a decreasing age-dependent trend in the patients observed with high OSA (P < 0.001). LIMITATIONS, REASONS FOR CAUTION This is a retrospective study. All males included in the study were undergoing a work-up for infertility and may not be representative of a fertile population. Additional patient demographics and clinical data were not available. WIDER IMPLICATIONS OF THE FINDINGS DNA and/or oxidative damage in sperm may be just as important to understand as the chromosomal aberrations that are carried in the oocyte. Further studies are needed to evaluate the effect of advancing paternal age on the male genome and, ultimately, on the health of the offspring.
