Human Sperm Morphology as a Marker of Its Nuclear Quality and Epigenetic Pattern.

Background: Human sperm chromatin condensation is a sum of epigenetic events that allows for the near-complete replacement of histones with protamines. Under high-magnification microscopy, nuclear vacuoles have been described as thumbprints with poor chromatin condensation. The objective of this study is to examine whether vacuolated spermatozoa carry specific epigenetic marks, which may influence embryo development.

For patients with non-obstructive azoospermia, the outcome of testicular sperm extraction correlates with self-esteem, sexual health and the quality of the couple's relationship.

Background: A very small number of studies have indicated that azoospermia or negative testicular sperm extraction (TESE) outcomes are linked to depression or erectile dysfunction. However, the data are often weak, conflicting and gathered with non-validated questionnaires. Hence, we performed a cross-sectional study of 44 men with non-obstructive azoospermia.

Place of patient-reported outcomes & experiences measurements (PROMS/PREMS) in the assessment and pricing of Health technologies in France.

In the context of health technologies assessment, patient-reported outcome measures (PROMs) have become assessment criteria that are expected by evaluation agencies along with the other usual clinical criteria. PROMs instruments measure all aspects of patient experience in connection with their health: symptoms, activities of daily living (physical function, sleep, etc.), various aspects of health-related quality of life (QoL), compliance, global impression of change in wellbeing.
