Table 1.
Comparison between fertilization rate, cleavage rate following IVF and ICSI procedures in oocytes containing different sizes of refractile/lipofuscin bodies and recovered from three stimulation protocols
| The size of the largest refractile/lipofuscin bodies (μm) | CC-antagonist | FSH/HMG-antagonist | Long protocol | ||||||
|---|---|---|---|---|---|---|---|---|---|
| <3 | 3–5 | >5 | <3 | 3–5 | >5 | <3 | 3–5 | >5 | |
| IVF fertilization rate | 86.4% (127/147) | 68.8% (8/11) | 66.6% (2/3) | 66.8% (193/289) | 47.4% (9/19) | 53.3% (8/15) | 84.5% (212/251) | 82.8% (24/29) | 68.0% (15/22) |
| Cleavage rate | 86.4% (127/147) | 68.8% (8/11) | 66.6% (2/3) | 66.1% (191/289) | 47.4% (9/19) | 46.7% (7/15) | 84.5% (212/251) | 82.8% (24/29) | 59.1% (13/22) |
| ICSI fertilization rate | 70.6% (48/68) | 60.0% (3/5) | 0% (0/1) | 69.1% (85/123) | 60.0% (9/15) | 87.5% (7/8) | 64.8% (46/71) | 66.7% (12/18) | 80.0% (4/5) |
| Cleavage rate | 69.1% (47/68) | 60.0% (3/5) | 0% (0/1) | 69.1% (85/123) | 60.0% (9/15) | 87.5% (7/8) | 64.8% (46/71) | 66.7% (12/18) | 80.0% (4/5) |
The size of the largest refractile/lipofuscin bodies in each of the oocytes/embryos were used to classify them into the three groups of <3, 3–5 and >5 μm.
