Because HIV virus will not affect the quality of eggs, female AIDS patients must have a physical examination and determine the viral load before the test tube cycle. In the process of assisting pregnancy, they will adopt "egg washing", that is, they will treat female eggs in order to obtain healthy eggs (virus-free) for use in test tubes in Thailand.

However, because egg washing is different from sperm washing in men, it may cause follicular rupture in the process of egg washing, destroy the quality of eggs, and often lead to no eggs available, so it is generally difficult for female patients to become Thai IVF. However, due to the technical differences between countries, it is also possible to achieve this in the United States.
