Definition - What does Conventional IVF mean?
Conventional IVF is one of two possible techniques used to achieve fertilization during an IVF cycle. It refers to a process where mature eggs and sperm and mixed together in a dish in a laboratory setting and fertilization occurs 'naturally.'
For this process to be successful, a large number of motile sperm are required; convention IVF is not effective in cases of severe male factor infertility.
FertilitySmarts explains Conventional IVF
From a patient perspective, the basic steps in an IVF cycle are the same regardless of how fertilization occurs. The basic steps include:
- Ovarian stimulation to bring about the development and maturation of eggs
- Surgical retrieval of eggs
- Fertilization of eggs
- Culture of embryos
- Embryo transfer back into a uterus
With issues like previous fertilization failure, low sperm count or motility, or when sperm have been surgically retrieved, conventional IVF may not be appropriate.
Intracytoplasmic sperm injection (ICSI) is an additional method to achieve fertilization by injecting a single sperm directly into the cytoplasm of an egg. This procedure requires few sperm and eliminates the need for the sperm to penetrate the egg independently.
