For a variety of reasons, sometimes the sperm cannot penetrate the outer layer of the egg. The egg’s outer layer may be thick or hard to penetrate or the sperm may be unable to swim. In these cases, a procedure called intracytoplasmic sperm injection (ICSI) can be done along with IVF to help fertilize the egg. In the ICSI process, a tiny needle is used to inject a single sperm into the center of the egg. See Figure 6.2 ICSI.
CARE Fertility is a leader in ICSI. Our clinic had the first baby born from ICSI in North Texas. We also had the first local use of ICSI for the treatment of male factor infertility.
