To establish sperm penetrating assay (SPA) with using cryopreserved hamster oocyte,
we performed the stepwise SPA with 1) fresh hamster oocyte and hamster sperm, 2)
cryopreserved hamster oocyte and hamster sperm, 3) fresh hamster oocyte and human
sperm, and 4) cryopreserved hamster oocyte and human sperm, in 4 cases of male
hamster and 12 cases of fertile human.
In SPA of hamster sperm with fresh hamster oocyte, the oocyte penetration rate (PR)
were 100¡¾0%, and the penetration index(mean penetration per oocyte, PI) was 22.4¡¾
1.8. In SPA of hamster sperm with cryopreserved hamster oocyte, the PR were 100¡¾
0%, and the PI was 14.1¡¾2.9 (p<0.01).
When the oocytes were examined at 1, 2, 3, and 6 hour post insemination, hamster
sperm penetration was 1 hour slower in cryopreserved oocytes than in fresh ones.
In SPA of human sperm with fresh hamster oocyte, the PR was 79.5¡¾10%, and the
PI was 2.78¡¾2.6. In SPA of hamster sperm with cryopreserved hamster oocyte, the PR
was 73.9¡¾ 16%, and the PI was 2.82 ¡¾ 2.7. There's no significant difference in SPA
using human sperm.
These results suggest that there may be some functional damages on cryopreserved
oocyte, because PI of fresh oocytes is higher than that of cryopreserved oocytes.
However in sperm of human, it dose not make significant difference in PI between fresh
and cryopreseNed oocytes. The SPA using cryopreserved hamster oocyte would appear
to have wide application of the evaluation of infertility, the assessment of the treatment
of infertility and the experiment in infertility field.
