| What are the advanced treatment options? |
|
|
Advanced treatment options are offered depending on the nature and complexity of the problem - if the doctors feel it is essential. |
|
|
ICSI & ET |
|
|
These are offered if the patient has |
 |
Obstuctive Azoospermia & Severe Oligospermia |
 |
Undergone a failed IVF |
|
Unexplained infertility |
|
|
| Sperms are recovered from ejaculation or collected by |
|
TESE (Testicular Sperm Extraction) |
|
MESA (Microsurgical Epididymal Sperm Aspiration) |
|
PESA (Percutaneous Epididymal Sperm Aspiration) |
|
|
| Procedure: A single sperm is injected directly into the cytoplasm of the egg by micropuncture of the egg shell. Fertilization rate is 60-70% and pregnancy rate is 20-40%. Then the embryo is replaced in a procedure similar to IVF/ ET. |
|
| Cryopreservation |
|
| Usually in IVF/ ICSI cycles more embryos are produced but only 3-4 are transferred into the uterus. The other embryos are frozen and can be used at a later date if the cycle fails. |
|
| Assisted hatching |
|
| Hatching of the blastocyst from the egg shell is required for implantation. In assisted hatching the egg shell is artificially thinned / opened with laser or acid tyrode solution. It improves the implantation rate. |
