Test Your Fertility Knowledge

Question: Fertilization via Intracytoplasmic Sperm Injection (ICSI) is performed when - 

  1. Sperm is placed with eggs in an incubator overnight
  2. A single sperm is injected into an egg
  3. Sperm is placed directly into the uterus

In the ICSI process, a tiny needle, called a micropipette, is used to inject a single sperm into the center of the egg. With either traditional IVF or ICSI, once fertilization occurs, the fertilized egg (now called an embryo) grows in a laboratory for 1 to 5 days before it is transferred to the woman’s uterus (womb).

ICSI helps to overcome fertility problems, such as:

  • The male partner produces too few sperm to do artificial insemination (intrauterine insemination [IUI]) or IVF.

  • The sperm may not move in a normal fashion.

  • The sperm may have trouble attaching to the egg.

  • A blockage in the male reproductive tract may keep sperm from getting out.

  • Eggs have not fertilized by traditional IVF, regardless of the condition of the sperm.

  • In vitro matured eggs are being used.

  • Previously frozen eggs are being used.
