I will likely need to be there near retreival , but the donor has to be there for about 10 days . My clinic is very rigid about this . They repeat every single test themselves , including infectious disease testing , hysteroscopy etc . They are actually going to repeat all of my workup saying that it has expired . I asked them why I am repeating a hysteroscopy for instance and the answer was that I could have developed a fibroid or polyp in the two years time that has lapsed since my last hysteroscopy . They are very thorough and rigid , which is painful but worth it in the long run ( I hope ).
