Anti-Mullerian hormone (AMH) is a marker for ovarian reserve. There are many studies about AMH changes in ovarian surgery, but little is known for other surgeries. We seek to investigate the hormone variations before and after uterine artey ligation for postpartum hemorrage (PPH)

All patients belong to the same group. The blood samples will be collected at the time of surgery and 3 months after surgery from the patients who need uterine artery ligation for PPH. The blood samples will be centrifuged within 2 hours after being obtained and assessed on the same day. AMH concentrations will be measured with an enzymatically amplified two-sided immunoassay

Inclusion Criteria:

• age 18- 40 years
• no systemic or endocrine diseases
• patients who had uterine artery ligation due to PPH

Exclusion Criteria:

• Pregnancy with IVF or oosit donation
• Patients with endocrinopathy, diseases which require radiotherapy and chemotherapy etc.
• Patients with BMI >40

Patients who need artery ligation for PPH during C-section.
