Table I.

Detection of mRNA for the prostate and testis expression (PATE)-like genes by RT–PCR in 95 human testicular biopsies, categorized according to histological pattern.

Gene	Pathology
	Obstructive (normal) (n = 17, %)	Focal spermatogenesis (n = 36, %)	Maturation arrest (n = 8, %)	Sertoli cell only (n = 34, %)
PATE	100	78	100	3
PATE-M	100	72	100	9
aPATE-B	33a	0a	Not tested	0a

The percentage of biopsies expressing the PATE-like genes was calculated for each category.

n, number of specimens.

^aTested in 6 obstructive, 23 focal spermatogenesis and 2 Sertoli cell-only specimens.
