ICSI
ICSI Fertilization Techniques
Intra cystoplamic sperm injection (ICSI): This is an advanced technique which has revolutionized the treatment of male infertility. It has raised the hopes of many men who previously had little or no chance of fathering their own children. The eggs are retrieved in the same way as in IVF but the sperm retrieved from the husband is injected directly into the center of the egg This effectively overcomes the final barrier to fertilization, which is the zoona pellucida or outer shell of the egg. It is usually recommended for men with only testicular sperms or extremely low counts or motility This procedure is also used in couples in whom fertilization in previous cycles was not successful.
At our centre ICSI is done with sperms which are obtained from any of the following sources:
(A) Ejaculated sample of semen
(B) From urine in case of retrograde ejaculation
(C) TESE: Testicular sperm extraction
(D) TESA: Testicular sperm aspiration
(E) PESA: Percutaneous epididymal sperm Aspiration
