To increase the frequency of pregnancy, various methods of genetic research are carried out:
- pre-implantation genetic testing of embryos by NGS and CGH;
- a study of a couple to bear monogenic diseases;
- a molecular genetic endometrial study to determine the level of receptivity and optimal period for embryo transfer;
- non-invasive prenatal test for detection of fetal chromosomal disorders;
- medical and genetic counselling of a married couple.
