The birth of quail chicks after intracytoplasmic sperm injection

Ultrastructure 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...

Failed 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...

The Effects of Maternal and Paternal Body Mass Index on Live Birth Rate after Intracytoplasmic Sperm Injection Cycles

Objective The present study was designed to evaluate the effect of couple`s obesity simultaneously on in-vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) outcomes. MaterialsAndMethods This cross-sectional study was performed in Royan institute between January 2013 and January 2014. The recorded data of all patients during this time period were evaluated. The study population was ...

Intracytoplasmic Sperm Injection

Intracytoplasmic Sperm Injection (ICSI) is an assisted reproductive technique [4] (ART) initially developed by Dr. Gianpiero D. Palermo [5] in 1993 to treat male infertility [6]. It is most commonly used in conjunction with in vitro [7] fertilization [8] (IVF) or a less commonly used technique called zygote intrafallopian transfer [9] (ZIFT). In natural fertilization [8], the sperm [10] must pe...
