This work is the result of many years of daily scientific and practical work aimed at improving diagnosis and finding new treatment options for patients with pregnancy loss, infertility and IVF failures. We have achieved good results in solving problems of reproductive disorders. And all this would not have been possible without our teachers, who have contributed enormously to our development as professionals, allowing us to engage in science and practice at the same time, which is very valuable and not accessible to everyone. Thank you to our teachers for instilling in us a love of our profession and our patients.
