Abstract

Subzonal insemination (SUZI) and intracytoplasmic sperm injection (ICSI) were carried out in 300 treatment cycles in couples unable to be helped by conventional in-vitro fertilization treatment. More oocytes were damaged by ICSI (13.5%) than by SUZI (7.1%). The normal fertilization rate was substantially higher after ICSI (51.0%) than after SUZI (14.3%) and was related to the semen characteristics. The cleavage rate was similar for both procedures (77%). After 217 embryo transfers (72.3% of the treatment cycles) 66 pregnancies were established, i.e. pregnancy rates of 22.0% per started cycle and 30.4% per embryo transfer. So far, pregnancy loss has occurred in 27.3% of the pregnancies, nine healthy children have been born after eight deliveries and 41 clinical pregnancies are progressing uneventfully. Chorionic villus sampling or amniocentesis have been performed in 35 pregnancies and 39 normal fetal karyotypes have been obtained after cytogenetic analysis.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
