ICSI may be performed due to failed fertilization with IVF or male infertility such as low count, low motility and poor quality of sperm. In cases with no sperm in the ejaculate due to a blockage, sperm aspiration or testicular biopsy may be performed to retrieve the sperm for ICSI.
ICSI is currently the most successful form of micro manipulative assisted fertilization available for male factor infertility.
