Abstract

Unexplained recurrent pregnancy (uRPL) loss is a devastating and challenging condition for couples as well as clinicians. One of the greatest challenges is not being able to identify the baseline etiology of recurrent pregnancy losses (RPL) when all the routine and recommended investigations return normal or negative. Pregnancy losses that are not seen on the ultrasound or are confirmed only based on decreasing urine or serum beta-hCG’s are termed as non-visualized pregnancy losses (NVPLs).

The three different types of miscarriages include visualized pregnancy losses (VPL), NVPL, and a combination of both (mixed). The second objective was to assess the idea of stratifying uRPL women into Type 1 (age ≥35, NVPL) and Type 2 (age
