ABSTRACT
To define the different causes of recurrent pregnancy loss [RPL] among Omani women. This retrospective study included all women with RPL seen between June 2006 and March 2012 in the RPL outpatient clinic in Sultan Qaboos University hospital, Muscat, Oman. The data were collected from the Hospital Information System by screening the electronic records of these patients. The sample size gathered during the study period was 290 women. One hundred and forty [48%] of the examined patients had an identifiable cause for RPL, while in 150 [52%], no cause was identified. The most common causes were immunological factors [35.4%] and the least common were environmental factors [1.7%]. Other causes implicated included: chromosomal abnormalities [8%], anatomical factors [9.4%], endocrine disorders [29.8%], infectious causes [3%], and thrombotic causes [12.7%]. Recurrent pregnancy loss is prevalent among Omani women. The etiological profile of RPL in Omani women is consistent with that reported elsewhere according to previously published studies, with minor variations
