There was a significant relationship between HM and history of molar pregnancy and multiparity (OR: 2.1; CI: 1.77-2.48; p=0.01, OR: 1.85; CI: 1.07-3.6: p=0.04)<span dir="RTL">.</span><br> <strong><em>Conclusion:</em></strong> The present study also showed that HM was more likely to occur in multipara patients and patients with history of molar pregnancy.
