Ovarian torsion is a rare entity and the diagnosis is commonly missed. Here we present a series of two cases of ovarian torsion. First case followed the in vitro fertilization treatment, along with ovarian hyperstimulation syndrome, where even with timely intervention and laparoscopy, we had to compromise one ovary. Second case followed the ovulation induction and intrauterine insemination - where timely intervention helped us to save the ovary.
