Is sperm head morphology related to high deoxyribonucleic acid stainability assessed by sperm chromatin structure assay?
The observed relationship between sperm head defects and %HDS suggests that sperm head abnormalities may, in part, be due to incomplete sperm chromatin condensation.
The present study revealed an unexpectedly high prevalence of optic nerve atrophy in homeless people. The prevalence for cataract and legal blindness was slightly higher than in representative epidemiological investigations. Thus, homelessness seems to be correlated with an increased ocular morbidity. As best-corrected visual acuity differed significantly between eyes with and those without eye disease, the assessment of this parameter may serve as a cost-effective first-stage screening method.
