AMH and Infertility: To analyze the effects of confounders on blastocyst collapse and embryo ploidy, we collected six patient and cycle characteristics (age,  body mass index (BMI), infertility duration for each female patient; level of follicle-stimulating hormone (FSH), level of anti-Müllerian hormone (AMH), and time of ovarian stimulation for each cycle) that might be associated with embryo ploidy.
