From patient charts we will review patients who had undergone cesarean section within the last 6 months and identify those who received a The Hayman uterine compression suture for uterine atony. We will also select patients who delivered a baby without recieving a Hayman suture to create a control group. Patietns will be grouped as Hayman Group if they recevied a Hayman suture during C/S and control group if thay had not recevied a Hayman suture. We will then check patient charts for post-cesarean outpatient clinic visit and select those who received ovarian reserve evaluation via hormones and antral follicle count during the visits. Finally, we are planning to investigate any correlation between Hayman suture and ovarian dysfunction.

Hayman suture is a common technique for uterine compression to stop bleeding due to uterine atony. Hayman described placement of two to four vertical compression sutures from the anterior to posterior uterine wall without hysterectomy. It is usually employed to overcome uterine atoy dıring cesarean section. However, since the technique is relatively new, data on its safety and efficacy arelimited to a few case reports. several complications including cavity obliteration, blood entrapment and infections have been described. However, data regarding the ovarioan function is lacking.
