Clinical Study on the Effect of Bilateral Ligation of the Ascending Uterine Artery on Ovarian Function in Patients with Postpartum Hemorrhage
This two-year clinical study demonstrates that bilateral ligation of the ascending uterine artery effectively controls postpartum hemorrhage during cesarean sections without significantly impairing maternal menstrual recovery, ovarian function, reserve, or blood perfusion, establishing it as a safe and effective treatment for refractory hemorrhage.

Imagine your body as a bustling city with a complex network of roads delivering fuel (blood) to every neighborhood. Some neighborhoods, like the ovaries, are the city's power plants, producing the hormones that keep the reproductive system running. Usually, these power plants have a main highway (the ovarian artery) and a smaller, helpful side street (a branch from the uterine artery) that brings extra fuel. Now, imagine a crisis: a massive flood (postpartum hemorrhage) is threatening to wash away the city after a baby is born. To stop the flood, doctors sometimes have to close off a major road leading to the uterus. But here's the big worry: if we block that road, will the power plants run out of fuel? Will the city's energy production crash? This is the question doctors have been debating. If the "side street" is the only thing keeping the power plant alive, closing it could be a disaster for a woman's future ability to have more children. But if the main highway is strong enough to handle the load on its own, then closing the side street might be a safe, life-saving move.
This study set out to settle that debate by watching what happened to 100 women who had just given birth via C-section and were bleeding too much. Half of them had the "side street" (the ascending branch of the uterine artery) tied off to stop the bleeding, while the other half had their bleeding stopped using traditional methods like packing the uterus with gauze or inflating a balloon. The researchers didn't just check if the bleeding stopped; they followed these women for two years, acting like detectives looking for any signs that the power plants were struggling. They checked the women's monthly cycles, measured the size of their ovaries, counted the tiny eggs waiting to be released, and even looked at how fast blood was flowing through the ovarian roads using ultrasound. They wanted to see if the women who had the artery tied off ended up with "power outages" (hormone imbalances, irregular periods, or reduced egg supply) compared to the women who didn't.
The results were a huge relief for the doctors and the women. After two years of careful watching, the study found that the women who had the artery tied off were doing just as well as the women in the control group. Their periods returned on time, their flow was normal, and they ovulated (released eggs) at the same rate. When the researchers looked at the "power plants" themselves, the ovaries were the same size, held the same number of waiting eggs, and produced the exact same levels of hormones like AMH, FSH, LH, and E2. Even the blood flow measurements showed that the ovaries were getting plenty of fuel, proving that the main highway was more than enough to keep the power plants running smoothly even after the side street was closed.
The study suggests that tying off this specific artery is a safe and effective way to stop dangerous bleeding without hurting a woman's future fertility or hormonal health. The researchers found no evidence that the procedure caused the ovaries to shrink, run out of eggs, or stop working. While the study had some limits—like being done at just one hospital and having a relatively small group of people—the data collected over two years points to a clear conclusion: the body has a clever backup system. The ovaries can reroute their fuel supply through other connections, meaning that this surgical trick to stop a flood doesn't have to cost a woman her power plant. It's a win for saving lives today without sacrificing the ability to grow a family tomorrow.
