Intracytoplasmic sperm injection (ICSI) is a highly sophisticated technique for injecting one single sperm into an egg using microscopic and micromanipulation instruments. In men with low sperm count, low motility or a high number of abnormal sperm, this technique has proven to be a highly successful remedy.

Combined with IVF or ZIFT, the procedure of ICSI is able to achieve a high rate of fertilization and normal embryo development. ICSI has even been successful in cases where sperm must be taken directly from the testes (testicular biopsy) due to the absence of sperm in the ejaculate or a previous vasectomy. ICSI is also the best choice when other andrology tests identify a possible problem with sperm function.

ICSI & IVF

ICSI is a more aggressive approach compared to traditional IVF. During a traditional cycle of IVF, the sperm and eggs are introduced together in a cultured medium, while the ICSI procedure takes an individual egg and microscopically inseminates it with an individual sperm. The successfully fertilized eggs are observed, graded for quality and reintroduced to the mother’s uterus.
