| ICSI is a treatment for male factor infertility. Male factor infertility is characterized by low sperm numbers, abnormally shaped sperm, and/or compromised sperm swimming ability (low motility). In addition, ICSI may be used for patients who have experienced failed fertilization in a previous IVF cycle. Even when no sperm are present in the ejaculate, sperm can be retrieved from the testis by a urologist and ICSI performed to achieve fertilization.
ICSI is a sophisticated microscopic surgical technique performed by an experienced embryologist. Eggs are first retrieved and placed in a tiny drop in a dish. While viewing the egg and sperm through a microscope, a single sperm is captured in a fine glass needle and injected through the eggshell and into the center of the egg (cytoplasm). Successful fertilization is evaluated the following day. Three to five days after ICSI, the physician transfers embryos into the woman’s uterus.
