In Vitro Fertilization (IVF) is a fertility treatment used to help couples conceive a child. In this procedure, an egg (from the female partner or from a female donor) and a sperm (from the male partner or from a male donor) are combined together in the laboratory. In IVF with Intracytoplasmic Morphologically-selected Sperm Injection (IMSI), sperm cells from the male are examined, and one healthy, normal sperm cell is selected in the laboratory to be injected directly into each egg. This selection process decreases the chances that an abnormal sperm cell will fertilize the egg. The combination of egg and sperm forms an embryo that can be implanted into the uterus of the female partner or a gestational carrier (another woman who will carry the baby).
