Table 1. Development of oocytes fertilized with rat epididymal or testicular sperm after freeze-drying.^a .

Sperm collected from	Diamide treatment	No. of oocytes transferred	No. (%) of oocytes implanted^b	No. (%) of offspring^b
Epididymis	−	54	15 (28)^a	6 (11)
Testis	−	36	0 (0)^b	0 (0)
Testis	+	50	4 (8)^b	4 (8)

Freeze-dried ampoules were stored for less than 1 month.

Percentages calculated from the number of oocytes transferred.

Within columns, percentages with different letters were significantly different (P<0.05) by analysis of χ² tests with Yates correction for continuity.
