Miscarriage and clinical correlates of leukocyte count in patients with ovarian hyperstimulation syndrome.

This study was conducted to determine the pregnancy outcome in women with ovarian hyperstimulation syndrome and leukocytosis. From a total of 944 women who underwent IVF-ET, 89 (9.4%) developed OHSS, of whom 67 underwent embryo transfer. The criteria of the study were met by 53 women and underwent WBC count and haematological, hormonal and biochemical tests were performed on the day of HCG administration. Statistical comparison was made between women with a WBC count of >15,000 and those with a WBC count of <15,000. Patients with WBC count of >15,000 at the time of HCG administration (n = 24) had significantly increased rate of early pregnancy loss than women who had WBC count of <15,000 (n = 29). No other blood, chemical and hormonal parameters were different between the two groups. It is concluded that women with ovarian hyperstimulation syndrome in an IVF-ET cycle are more likely to miscarry if they have a WBC count of >15,000 on the day of HCG administration.
