Table 1. The results of ROSI with spermatids from males with a single or no Y-chromosome genes.
Column heads 2 to 4: Males with round spermatids identifiable in live testicular cell suspension out of males examined. Males yielding progeny out of the number of males that yielded embryos used for embryo transfer and induced pregnancy. Live offspring as a percentage of embryos transferred.
| Male genotype | Y gene contribution | Males with round spermatids (%) (no.) |
Males yielding progeny | Live offspring (%) (no.) |
|---|---|---|---|---|
| XEOSox9 | Eif2s3y | 80 (8/10) | 7/8 | 15.7 (18/115) |
| XOSry,Eif2s3x | Sry | 55 (17/31) | 16/17 | 22.5 (57/253) |
| XOSox9,Eif2s3x | None | 27 (13/48)a | 9/10 | 20.7 (46/222) |
| XY control | Intact Y | 100 (6/6) | 6/6 | 25.0 (22/88) |
Statistical significance (Fisher’s exact test, P < 0.05):
