For Whom is IVF Recommended?
Normally the egg that is released by the ovary it is ‘caught’ by one of the fimbriae and transported along the fallopian tube to the uterus. Fertilization usually ocurrs in the tubes and then the developing embryo implants in the uterus about one week after ovulation. When the egg is fertilized and cultured outside the body, this is called In Vitro Fertilization (IVF). The most common reasons for IVF are:
- Blocked tubes
- If sperm count is too low to fertilize the egg in vivo or if the quality is poor
- When there’s no sperm in the ejaculate, in which case a tissue sample is taken from the testes and sperm from the sample, if found, is used for microinjection into the egg.
- Immunological problems
- Unexplained factors causing difficulty to conceive even after artificial Insemination or ovarian stimulation.
