IntraCytoplasmic Sperm Injection (ICSI)
Intracytoplasmic sperm injection (ICSI) is procedure in which the sperm of your partner is injected directly into your egg. It is different from the traditional vitro fertilization (IVF) procedure. This procedure is required when there are very few sperm available. In ICSI, the sperm need not to travel to the egg to penetrate it.
Your doctor will recommend ICSI if:
- There is a very low sperm count
- The sperm have other problems like abnormal shape (poor morphology) or abnormal motility.
- The previous IVF has failed
- If the production of the sperm is also low or you had vasectomy, so the sperm are collected surgically from the testicles.
- Your frozen sperm are not of good quality
- There is any blockage or anatomical abnormality reproductive tract of a man and the sperms cannot be produced or ejaculated.
How Does ICSI Work?
The ICSI procedure involves the following:
The ovaries of women are stimulated through fertility drugs to increase the production of eggs. The eggs are then collected and then the sperm is injected in each egg. The rest of the procedure is similar to the IVF. There are chances of having multiple pregnancies as a result of this procedure. But the doctor will transfer the single embryo if you don’t want to have multiple pregnancies.
You are able to provide the sperm only if you can make fresh sample of sperm on the day the eggs of your partner are collected. Also if it is possible to collect the sperm from epididymis with the help of fine syringe, and you are willing for testicular sperm aspiration then you can provide the sperm. There is one more possibility of collecting the sperm. It is that a tiny quantity of the testicular tissue is removed and the sperm are extracted from that tissue.
After the collection of the sperm, a single sperm is then injected in each egg so that the egg may get fertilized. This procedure is effective but there is no guarantee of its success.
When there is a successful fertilization, the embryo is cultured in laboratory for 6 days minimum. The best quality embryo is then transferred to the womb.
This is the best treatment of infertility of men. But it is not the solution to all types of infertility problems.
Success Rates Of ICSI
This procedure is more successful than IVF. But the success mainly depends on the type of infertility the man has and his age. If a woman is younger, her eggs are of good quality so the chances of success are also more.
The success percentage of cycles using ICSI is:
- 35 percent – under 35 years’ age
- 29 percent- between 35 to 37years
- 21 percent – between 38 and 39
- 14 percent – between 40 and 42
- 6 percent between 43 and 44
- 5 percent – over 44
This is the best procedure to have a genetic child if you don’t have any other option of becoming parent.
