title: [Prolonged desensitization pretreatment for in vitro fertilization in women with polycystic ovary].
abstract: OBJECTIVE
  To analyse the outcome of intracytoplasmic sperm injection (ICSI) in women with severe polycystic ovary disease (PCD), stimulated after prolonged pituitary desensitization in comparison with regular long protocol therapy.
  
  
  METHODS
  The results of controlled ovarian hyperstimulation (COH), fertilization rate, early embryo development parameters and clinical pregnancy rates were compared depending on the duration of pituitary desensitization before gonadotropin administration. A total of 60 patients with severe PCOD were desensitized with GnRH agonist up to 30 days before COH. The results were compared with the group of 213 patients with mild PCOD treated with regular long protocol (control).
  
  
  RESULTS
  We observed a slightly higher rate of mature oocytes MII as well as the number of embryos obtained in the control group, however the pregnancy rate in the group with prolonged desensitization was significantly higher (50%) in comparison to the control group (33.8%).
  
  
  CONCLUSIONS
  The prolonged pituitary desensitization before controlled ovarian hyperstimulation gives better chance for obtaining pregnancy in patients with severe PCOD. It could be recommended facing previous treatment failure.
