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...

IVF has become a well-established treatment for certain types of infertility, including long-standing infertility due to tubal disease, endometriosis, unexplained infertility or infertility involving a male factor. Soon it became clear that certain couples with severe male-factor infertility could not be helped by conventional IVF. Extremely low sperm counts, impaired motility and/or abnormal m...
متن کاملEffects of Sperm Chromatin Integrity on Fertilization Rate and Embryo Quality Following Intracytoplasmic Sperm Injection
Sperm chromatin integrity has been being recognized as an important factor in male fertility. During normal fertilization, high quality sperm with intact chromatin are selected through natural selection in journey from vagina to fallopian tube. However, using Assisted Reproductive Techniques, particularly ICSI, the natural selection is bypassed. Therefore sperm with DNA breakage have the opport...
متن کاملIndications for intracytoplasmic sperm injection.
Intracytoplasmic sperm injection (ICSI) is the latest of several microfertilization techniques that have been utilized predominantly to overcome severe male subfertility, giving fertilization and term pregnancy rates similar to conventional in-vitro fertilization (IVF) (but for other indications). Even though available data on children born after ICSI are very encouraging, the procedure must st...
