The intracytoplasmic sperm microinjection (ICSI) is a process of fertility assisted that closely resembles the conventional in vitro fertilization or IVF but the difference is that the insemination of the eggs is done by introducing a sperm with a microneedle.
This technique is one type of artificial insemination and much more complex that in vitro fertilization IVF is so much more expensive and more range of effectiveness in special cases.
The procedure in this treatment is similar to in vitro fertilization IVF, but in this case the oocytes are inseminated artificially by introducing a micromanipulator to insert a sperm into each mature egg. Complications that can result in this method are the same as those of conventional IVF.
Intracytoplasmic sperm microinjection is recommended in cases of:
Infertility of male: in cases of men who have Cryptozoospermia, oligozoospermia, asthenozoospermia, azoospermia, teratozoospermia, and oligoasthenoteratozoospermia oligoasthenozoospermia. Also in cases of men who underwent vasectomy or who have an infectious disease, who have frozen semen or who can not get an ejaculation.
Women infertility: ICSI is used in women with a low number of oocytes, oocytes obtained with thickened zona pellucida or have poor quality oocytes.
Pregnancy failures in previous attempts with conventional IVF
Failures in fertilization of the oocytes with conventional IVF
In vitro maturation of cases of immature oocytes
Microinjection of oocytes fertilized with conventional IVF
In cases where you need a preimplantation genetic diagnosis (PGD) because of genetic problems or parents to know that embryos are genetically normal.
In cases of immune infertility by low anti-sperm antibodies and previous failures in artificial insemination cycles, as well as in situations of immune infertility with lots of anti-sperm antibodies.
