Reproductive hormone reference intervals for healthy fertile young men: evaluation of automated platform assays.

Context: Management of male infertility and/or androgen deficiency requires accurate hormonal measurements with valid reference intervals.

Objective: The objective of this study was to develop a valid reference panel of blood samples from healthy eugonadal young men with verified normal reproductive function and to use this panel to evaluate the performance of seven fully automated, commercial multiplex immunoassay platforms used to measure serum total testosterone (T), LH, and FSH.

Design: This was an observational study of consistency among seven different automated immunoassays for each of total T, LH, and FSH.

Oral medicine and oral pathology--the impact of electronic information.

This paper discusses recent advances in electronic information, with particular reference to Oral Medicine and Oral Pathology. Email has become the norm for professional communication; Medline is freely accessible; content alerts can be established to alert the subscriber to new publications; evidence-based practice is emerging with the development of the Cochrane library and numerous other databases are also available for a variety of purposes. Conferences are moving to use electronic information as the medium for dissemination of proceedings.
