Tunica vaginalis fluid (TVF): hormonal composition. Assessment of testosterone, 5 alpha-dihydrotestosterone, delta 4-androstenedione, dehydroepiandrosteronesulphate, estradiol, LH, FSH and PRL.

Up to now little or no attention has been paid to the tunica vaginalis fluid (TVF), that is usually found between the inner and outer layers of the tunica vaginalis of the testis. The aim of this work is to evaluate in 33 patients whether TVF may be considered to reflect to some extent male gametogenic function. Authors' data support the view that TVF is probably a transudate reflecting concentration of steroid hormone levels at the site of their action.
