What is ICSI Treatment?
Just as IVF revolutionized the treatment of female-caused infertility, Intra-cytoplasmic sperm injection (ICSI) was introduced as a major breakthrough in the treatment of male-caused infertility in which a single sperm is directly injected into the body (cytoplasm) of the egg.
It is especially useful for patients where the male partner has a very low sperm count (oligozoospermia), poor sperm motility (asthenozoospermia) or too many abnormal sperms (teratozoospermia). Also, in men with obstructive azoospermia (zero sperm counts because of some obstruction in the ducts), sperm can be directly retrieved from the upper part of the testis called the epididymis (PESA-percutaneous epididymal sperm aspiration) and in cases of non-obstructive azoospermia, sperm can be retrieved directly from the testis (TESA – testicular sperm aspiration) and used for ICSI, thus helping them to have their own biological offspring without resort to a donor sperm.
More recently, we perform microsurgical testicular sperm aspiration using microscopes and multiple biopsies especially in cases of testicular failure with very small testes or high FSH levels (indicating testicular failure) and obtain sperm which are capable of fertilization
