  • Males having a low sperm count.
  • Woman who have under gone IVF treatment before and none or only a few eggs fertilized.

No doubt, ICSI technique increases the success rate of the procedure but you should also be aware of the risk associated with this treatment.

Given below are some of the risk related with ICSI

The success rate of ICSI is high i.e around 50 to 80 percent but it is not necessary that all the fertilized eggs will get developed into healthy embryos. Also, this technique helps in fertilizing egg even if the sperm is not healthy enough which could result in defective embryos.

Further, the risk associated with ICSI is the same as that of children conceived naturally. But the child conceived by ICSI would have very low birth defects, less than 1%. According to researchers, the birth defects can be because of sex chromosome abnormalities, urinary system or genitals defects and lower quality sperm. But there are rare chances that this will happen.

However, the main risk associated with ICSI is actually a risk of IVF itself because of an increased chance of multiple births. This risk can be minimized by cautiously and attentively controlling the number of embryos that are to be transferred in the female's uterus. Multiple births i.e twins, triplets or more than that results in a high rate of risk and complications to both mother and babies.


Precautions to be taken after an ICSI treatment are :

  • Smoking should be avoided along with the consumption of alcohol.
  • Before taking any medication always consult your doctor.
  • Exercises like jogging, aerobics and weight lifting are strictly prohibited.
