title: Real and expected delivery rates of patients with myotonic dystrophy undergoing intracytoplasmic sperm injection and preimplantation genetic diagnosis.
abstract: BACKGROUND
  This study aimed to analyse the reproductive outcome of a large cohort of myotonic dystrophy type 1 (DM1) patients undergoing ICSI and PGD. The secondary outcome parameter of this study was ovarian response as a way to express gonadal function in female DM1 patients.
  
  
  METHODS
  Prospective cohort study. Real and expected cumulative delivery rates are descriptive. The reproductive outcome per cycle was compared with that of a control group of patients with X-linked recessive disorders. The comparative analysis of ovarian stimulation parameters in the study group versus the control group was carried out using both bivariate (crude) and multivariate (linear regression) analysis.
  
  
  RESULTS
  Between 1995 and 2005, 205 cycles of ICSI and PGD were carried out for DM1 in 78 couples. The real cumulative delivery rate (max 6 cycles) overall was 46%. The expected overall cumulative delivery rate was 72%. Multivariate analysis did not show a significant difference in total dose of gonadotrophins used for ovarian stimulation between Group A (in which the female partner was affected) and a control group.
  
  
  CONCLUSIONS
  This study shows that ICSI and PGD for DM1 offer good reproductive outcome, both in cumulative terms and per treatment cycle. There is no evidence of impaired gonadal function in female DM1 patients.
