It is more common in assisted reproductive techniques. Delay in diagnosis and treatment results in functional loss of ovary as well as termination of pregnancy. In this report, we are presenting a case of 27 years female with subfertility who conceived after ovulation induction presented at 7 weeks 6 days period of gestation with ovarian hyperstimulation associated with adnexal torsion. Later, she was treated with laparoscopic salpingo-oophorectomy.
