The tests that need to be done for the first transplantation failure include chromosome karyotype analysis, endocrine examination, hysteroscopy and immunological examination.
1. Chromosomal karyotype analysis: the possible reason for the failure of fertilized egg transplantation is the chromosomal abnormality of sperm and egg, which leads to the failure of normal development of the fertilized egg generated by the combination, so it is necessary to check the chromosomal karyotype analysis.
2. Endocrine examination: mainly to check the endocrine level of the female partner, such as the level of estrogen and progesterone.
3. Hysteroscopy: Hysteroscopy is used to check whether the endometrium of the female uterus is normal or not, and whether there are any abnormal factors that prevent the fertilization of the egg.
4. Immunity test: If the patient has a history of recurrent influenza, it is recommended to check whether there are anti-sperm antibodies in the patient’s body.
