Impact of Paternal Age on Seminal Parameters and Reproductive Outcome of Intracytoplasmatic Sperm Injection in Infertile Italian Women. Front Endocrinol (Lausanne) 2019; 10:35.

Abstract
Background: We conducted a retrospective study on a cohort of couples attending the Department of Andrology and Reproductive Physiopathology at Sandro Pertini Hospital in Rome for Intracytoplasmatic Sperm Injection (ICSI)-assisted reproduction programs. Some of the couples included in the study underwent more than one ICSI cycle. Between January 2015 and April 2017. Objective: To evaluate whether the advancing of the paternal age may have effect on the seminal parameters, thus negatively affecting the embryo formation, development and quality, as well as the pregnancy rate. Materials and Methods: Five hundred and forty three ICSI cycles were performed on 439 couples undergoing Assisted Reproductive Technologies (ART). Patients were subdivided into three male and three female age groups having similar size: Men: ≤38 years (MI), 39-43 years (MII), ≥44 years (MIII). Women: ≤35 years (FI), 36-40 years (FII),≥41 years (FIII). Discussion and Conclusion: Male age groups did not reveal any statistical significant differences in any age-related semen parameters. We also confirmed a statistical significant increase in the pregnancy rate of couples with older partner age difference and younger female. We found that the advanced male age increases the probability of obtaining one or no type A embryo (NA≤1), which was almost doubled in the MIII group in comparison with MI, suggesting a negative effect of male age on the efficacy of the reproductive outcome in terms of a reduced number of type A embryos. Such an effect does not seem related to semen parameters and may deserve further investigations.

Abstract
BACKGROUND A family history of cancer is a marker of familially shared genetic and environmental risk factors for cancer but is subject to inaccurate and biased reporting. METHODS In a case-control study of adult acute leukemia, we examined the accuracy of cancer reports in deceased first-degree relatives using death certificates and the National Death Index (NDI). We submitted information on 1058 deceased relatives to the NDI or civil vital statistics registries. Social security numbers were not available and identifying information was incomplete. RESULTS A death certificate was located for 70% of records sent to state registries but for only 32% of records submitted to the NDI. Death certificates confirmed 95% of relatives reported to be cancer-free and 83% of those reported to have any form of cancer. Confirmation of cancer of specific sites ranged from 50% for breast cancer and 54% for leukemia to 86% for prostate cancer. CONCLUSIONS State searches may be preferable to the NDI when identifying information is incomplete.
