High quality RNA in semen and sperm: isolation, analysis and potential application in clinical testing.

Purpose: Male infertility is a complex health condition. To our knowledge there are no molecular biomarkers of male infertility. Sperm RNA is a potential biomarker for detecting sperm abnormalities and viability at infertility clinics.

Testicular touch preparation cytology in the evaluation of male infertility.

Background: Male infertility is traditionally evaluated by tissue core biopsies of the testes. Touch preparations (TP) of these biopsies have been infrequently used. The aim of this study is to report our experience with using testicular biopsy TP for the evaluation of male infertility.
