Intracytoplasmic Sperm Injection (ICSI)
Ovarian stimulation and egg collection in ICSI (intracytoplasmic sperm injection) and IVF are exactly the same. However, in an ICSI cycle each suitable mature egg is injected with a single prepared sperm cell. This is obtained from the partner or from a donor sperm sample.
ICSI was developed to treat cases of male infertility in which too few (or only poor quality) sperms were available in the ejaculate for in vitro fertilisation.
