Intra Cytoplasmic Sperm Injection (ICSI)

Intra Cytoplasmic Sperm Injection (ICSI) is most commonly performed for male factor infertility. This involves injecting single sperm into the cytoplasm of an egg with the help of a special instrument called micromanipulator.

ICSI Improves fertilization rate and offers scope to patients with:

Very few or no sperm in the ejaculate
Poor or no motility
Decrease in the number of normal looking sperms
Woman with less number of eggs
Older woman
History of failed fertilization in previous IVF cycles

The ovarian stimulation for ICSI remains same as an IVF cycle.

Surgical sperm retrieval techniques

If there are extremely few or no sperm found in the ejaculate (Azoospermia) we advise for sperm aspiration. Sperm aspiration is a procedure used to obtain viable sperm from a testicle which can be used later for ICSI.

Testicular biopsy is performed as an in-office surgical procedure in which several small pieces of testicular tissue are removed and examined for sperm which can be used in fertility procedures.

Testicular Sperm Aspiration (TESA) - A TESA procedure involves a needle biopsy of the testicle in which a sample of tissue is taken directly from the testis and used to extract sperm for ICSI.

Percutaneous Sperm Aspiration (PESA) - PESA is a procedure involving a needle inserted into the epididymis in an effort to locate and aspirate a pocket of sperms.

The extra sperms and testicular tissues obtained by TESA / PESA can be cryopreserved for future use.
