ICSI stands for Intracytoplasmic Sperm Injection. It is a specialized form of in vitro fertilization (IVF) used to treat male infertility issues. In traditional IVF, the sperm and egg are combined in a laboratory dish, and fertilization occurs naturally. However, in cases where the male partner has low sperm count, poor sperm motility, or abnormal sperm shape, ICSI is performed.
During ICSI, a single sperm is directly injected into the cytoplasm of an egg using a fine glass needle. This procedure bypasses the need for the sperm to naturally penetrate the egg's outer layer. The selected sperm is typically chosen based on its morphology and motility. The injected egg is then incubated in the laboratory, and if fertilization is successful, it develops into an embryo.
ICSI is a highly effective technique that allows couples with severe male infertility to achieve pregnancy. It is often recommended when other fertility treatments have failed or when there are significant male factor issues. ICSI can also be used in cases where the female partner has certain fertility problems, such as low egg quality or previous failed fertilization attempts.
Overall, ICSI has revolutionized the treatment of male infertility and has significantly improved the chances of conception for couples facing such challenges.
