HMN 2025: Hernias groin drugs reverses in male mice without surgery, it shows a promise in humans

Using a newcomer, based on medicines, a new Northwestern medicine study was successfully reversed in existing male mice and made their normal restoration completely without surgery. Even more promising, the scientists also examined human hernia tissue and found the identical molecular markers as in the mouse model. More than a million Inguinal Hernia Repair Surers per year are made under general anesthesia in the United States

“This is a major publication under the first medical treatment associated with inguinal hernias,” said the senior author, Dr. SERDAR BULUN, Chairman of the Department of Obstetrics and Gynecology at Feinberg Medical School Northwestern University and Northwestern medical doctor. “Our results strongly suggest that men would also respond to this medication as the male mice did, so if male patients are high for surgery, we can repair the hernias to medicine.”

Finally, the study found the most likely cause of inguinal hernias: estrogen-alpha receptor (ESR1), which plays a key role in the growth of certain tissue support cells and stimulating fiber tissue buildup, thus developing inguinal hernias .

The study was published today, February 4, in the Journal of Clinical Investigation.

How did the study work:

The study was broken into two experiments: one using modified male mouse models and one that examined human tissue.

In the mouse experiment, scientists introduced the anti-estrogen drug collision, which is currently permitted to treat some types of breast cancer, in a humanitarian mouse model designed to the higher estrogen levels found in men going in to recite age. When scientists blocked ESR1 in these supporting tissue cells, it prevented muscle damage and hernia formation. The use of Fulvestrant in the study banned the ESR1 in the mice, which helped to reduce large hernias and restore the mice to the healthy anatomy.

In the human hand of the study, the scientists made biops on each participant twice – one from the hernia site and another from a healthy muscle nearby – and they found the same biological markers and were in the mouse model. Further analysis showed that estrogen and ESR1 acts a series of genes linked to excessive tissue scarring, matching patterns seen in hernia tissue from human patients.

“We expect estrogen/ESR1 is a promising molecular goal to develop pharmaceutical treatments for inguinal hernia in men.” The corresponding author said. Hong Zhao, Professor of Midwifery and Gynecology Research (Reproductive Science in Medicine) by Feinberg.

More about inguinal hernias

Inguinal hernias also occur in women but often much less (one woman for every 34 men). They return to more than 10% of elderly male patients after attempting to surgical repair, which is about 100,000 elderly men per year, Bulun said. Although these hernias are not usually painful, patients can be very tunnel or even die if their bowel gets trapped and the hernia becomes strangulated.
