What are the differences between artificial insemination and IVF? Which is better?

They are distinct techniques and each one is suitable for specific cases.

Artificial insemination is simpler and it consists of depositing spermatozoa, which have been previously selected and improved in the lab, into the woman’s uterus at the optimum point of ovulation.

IVF is more complex because it first requires an egg retrieval process to extract the woman’s oocytes. These are then fertilised with the spermatozoa in the lab and developed for 2 to 5 days in special incubators. The resulting embryos are then deposited in the uterus with the expectation that the natural pregnancy process will continue.
