Intracytoplasmic Sperm Injection (ICSI)
The conventional IVF requires a critical number of motile sperm to achieve fertilisation. When the normal sperm number required is not enough for IVF, our embryologists can inject a single sperm into an egg cytoplasm, i.e. intracytoplasmic sperm injection (ICSI).
Sperms can be extracted for ICSI procedure from the testis or its appendages (vas or epididymis) of male patients with few or no sperm in their ejaculate (azoospermia). The technical terms for these procedures are testicular sperm extraction (TESE) or microsurgical epididymal sperm aspiration (MESA). After achieving fertilisation the procedure of embryo transfer is the same as IVF.
