Abstract:
The hypo-osmotic sperm swelling (HOSS) test was performed on semen samples of five normospermic men from couples with prolonged infertility. Previously, the men had negative results of the zona-free hamster oocyte (ZFHO) test on two different ejaculates and the wives subsequently had become pregnant by donor insemination. A high swelling percentage (at least 60%) was found in all five men. It would appear that the HOSS test does not assess fertilizing capacity.
