Intracytoplasmic Sperm Injection - ICSI
INTRACYTOPLASMIC SPERM INJECTION (ICSI) It is a process where in a sperm is injected via in vitro fertilization technique. This is required whence the sperm count in the male is very low. In ICSI a single sperm is injected in to the egg. If sperms are absent in ejaculate the extraction can take place directly from the testis. This is also known as testicular sperm extraction. It requires a micro manipulator which holds the egg by suction. Following this a sharp needle used to inject a single sperm to achieve fertilization. This technique is a boon for couples whence conventional IVF is not successful. This happens when the sperm count is very low or the sperms are non motile. HOW ICSI IS CARRIED IN OUR FERTILITY CLINIC? Like conventional IVF the stimulation protocol for the ICSI is similar. The egg removal is surgical as it is done in IVF. Normally eggs are covered by cell cluster referred to as cumulus corona cells. These cells must be removed completely before the sperm inj
