title: Surrogate in vitro fertilization outcome in typical and atypical forms of Mayer-Rokitansky-Kuster-Hauser syndrome.
abstract: BACKGROUND
  The genital malformations in Mayer-Rokitansky-Küster-Hauser syndrome (MRKH) are frequently accompanied by associated malformations whose forms were recently classified as typical (isolated uterovaginal aplasia/hypoplasia) and atypical (the addition of malformations in the ovary or renal system). The aim of this study was to compare the surrogate IVF performance of women with typical and atypical forms including their chances of achieving pregnancy.
  
  
  METHODS
  The follow-up data on a total of 102 cycles of surrogate IVF in 27 MRKH patients treated in our department between 2000 and 2010 were analysed. Twenty patients with the typical form who underwent 72 IVF cycles were compared with seven patients with the atypical form who underwent 30 IVF cycles. The various examined parameters of these intended mothers were age, hormonal profile during controlled ovarian hyperstimulation and laboratory outcome.
  
  
  RESULTS
  The mean number of gonadotrophin ampoules needed for stimulation and treatment duration was significantly higher in the atypical form (3600 ± 1297IU for 13 ± 2.3 days versus 2975 ± 967 IU for 11.6 ± 1.6 days, P≤ 0.01). Serum estradiol and progesterone levels measured on the hCG administration day were similar. A significantly higher mean number of follicles 12.6 ± 6 versus 8.9 ± 5.4, P≤ 0.03, metaphase II (MII) oocytes 8.7 ± 5.1 versus 6.7 ± 4.8, P≤ 0.05, fertilizations 6 ± 3.6 versus 4.4 ± 3.3, P≤ 0.03 and cleaving embryos 5.7 ± 3.8 versus 4.1 ± 3.3, P≤ 0.01 were available in patients with the typical form compared with those with the atypical form, respectively. There was no significant difference in fertilization rate, cleavage rate or the mean number of transferred embryos. Embryo quality of the transferred ones and pregnancy rate per cycle were also similar between the two groups.
  
  
  CONCLUSIONS
  Women with the typical form of MRKH needed fewer gonadotrophins and for a shorter duration for ovarian hyperstimulation. The mean number of follicles, oocytes, MII oocytes, fertilizations and cleaving embryos was higher among women with the typical form. Pregnancy rates were similar since the available number and quality of transferred embryos to the surrogate mother were not affected.
