ICSI is the only hope for the patient-
- Who do not ejaculate any sperm (cryptozoospermia).

Steps involved in ICSI
- Women is stimulated for follicle production and egg recovery as in IVF.
- Single sperm is selected from the semen or directly from the testis/epididymis by TESA/PESA.
- This single sperm is injected into cytoplasm of egg and are left for fertilization in an incubator as in IVF
- Transfer of embryo to the uterus occurs in the same routine manner as that for IVF. ICSI can be used for all types of sperm problems-even those with extreme condition.
