title: Response to controlled ovarian stimulation and oocyte quality in women with myotonic dystrophy type I.
abstract: OBJECTIVE
  In women the relationship between myotonic dystrophy type I and fertility remains controversial. The objective of this study was to evaluate the ovarian reserve, ovarian response to stimulation and oocyte quality in these patients.
  
  
  METHODS
  We compared 15 myotonic dystrophy type I patients with 39 age matched controls with isolated male factor infertility necessitating ICSI.
  
  
  RESULTS
  All parameters of ovarian reserve (day 3 FSH and E2, antral follicle count and delta E2) were significantly better in the controls. Despite having significantly lower doses of gonadotrophin, the control group attained a higher number of retrieved oocyte-cumulus complexes (p < 0.04). Analysis of cytoplasmic and extracytoplasmic dysmorphism did not reveal any difference between the two groups. Fertilisation rate and top grade embryos on day 3 were similar in both groups.
  
  
  CONCLUSIONS
  The present study suggests that though women with myotonic dystrophy type I have a reduced ovarian reserve and respond poorly to controlled ovarian stimulation, there is no impact on oocyte and embryo quality. Hence suggesting that successful ART is feasible with appropriate selection in women with mild myotonic dystrophy.
