Obstetric outcome after prenatal diagnosis in pregnancies obtained after intracytoplasmic sperm injection.
In this study we compared the pregnancy outcome of 576 pregnancies after prenatal diagnosis with that of 540 pregnancies without prenatal diagnosis in our microinjection programme. Amniocentesis was suggested for singleton pregnancies (n = 465) and chorionic villus sampling (CVS) was proposed for twin pregnancies (n = 111 pregnancies, 222 fetuses). A total of 365 patients with singleton pregnan...
متن کاملFailed fertilization after clinical intracytoplasmic sperm injection.
Intracytoplasmic sperm injection (ICSI) has resulted in pregnancy and birth for many couples, including those with severe male factor infertility. However, even after ICSI, complete failure of fertilization occurs in 1-3% of cycles. Most cases occur due to low number of mature oocytes, failure of oocyte activation or non-availability of appropriate spermatozoa for injection. Given the significa...
متن کاملMultiple pregnancies obtained by testicular spermatid injection in combination with intracytoplasmic sperm injection.
Recent studies have shown that the injection of spermatid cells into the human oocyte can result in normal fertilization, embryo development and even delivery of live, healthy offspring. In our study, 23 azoospermic cases with severe spermatogenetic defects in their testicular biopsy are presented. The serum follicle stimulating hormone (FSH) concentrations and histopathological results of thes...
متن کاملUltrastructure of gametes after intracytoplasmic sperm injection.
The ultrastructure of 18 metaphase-II oocytes after intracytoplasmic sperm injection (ICSI) was analysed from 30 min to 8 h following the microinjection. Three control metaphase-II oocytes were not injected. The 21 oocytes were embedded individually and examined in serial pole-to-pole sections. Seventeen oocytes had been matured in vitro from the germinal vesicle stage and showed ultrastructura...
متن کاملIntracytoplasmic sperm injection outcome versus intracytoplasmic morphologically selected sperm injection outcome: a meta-analysis.
The development of a modified intracytoplasmic sperm injection (ICSI), called intracytoplasmic morphologically selected sperm injection (IMSI), demonstrated that a profound morphological investigation of the spermatozoon, under the magnification of 6600 x, enables outcome improvement. The aim of this study was to compare ICSI outcome with IMSI outcome. The meta-analysis results demonstrated no ...
