ICSI is a process of egg fertilization by selecting a single sperm on a high magnification machine and injecting in an egg in order to bring fertilization. ICSI is offered to couples with severe male factor infertility, unexplained infertility, with poor fertilization in prior cycles, and entering treatment following failed insemination cycles. All surgically retrieved sperms from epididymis/testes in males with azoospermia (TESE: testicular sperm extraction) will be subjected to ICSI for fertilization.
Note: This is a lab procedure and for patients there is no difference in IVF procedure. At Sir Ganga Ram hospital there are no separate charges for ICSI. About 70 % of IVF cycles undergo ICSI.
Failure of fertilization or failure to form an embryo can occur in both IVF or ICSI cycles, though seen in very few cases. This is more seen in patients with advanced female partner age/extreme male factor infertility with abnormal sperms.
