A 31-year-old woman with primary infertility has successfully delivered  a baby after undergoing a novel Transvaginal Sonography in Mumbai recently. She visited Wockhardt Hospitals, Mumbai Central presenting with primary infertility of seven years due to polycystic ovaries and her husband`s oligoasthenozoospermia (OATS). 

Under Dr Rana Choudhary, consultant obstetrician, gynecologist & fertility specialist, the patient conceived via in-vitro fertilization (IVF), and all embryos were frozen. In a subsequent cycle, she underwent frozen embryo transfer (FET) and conceived a singleton. Her antenatal course was uneventful, but at 26 weeks, she reported heaviness and discomfort in the lower abdomen and vulva. Examination revealed a 26-week-sized uterus with no uterine contractions and a foetal heart rate of 140 beats per minute. A transvaginal sonography (TVS) revealed a short cervix (2.3 cm) with a closed internal Os.
