We need the results of the following examinations of the woman (if available):

Blood hormone levels, gynecological ultrasound scan, any x-ray pictures of the uterus and fallopian tubes (hysterosalpingography / HSG), reports of any abdominal surgeries, laparoscopies and hysterocopies as well as any other medical test results.
From the male side we will need the following results: spermiogram results (semen examinations) which shouldn’t be older than 6 months and if possible results of an urologist’s examination
(this helps evaluate if and to what degree the mans fertility is reduced).
