Table of Contents
An international research team from China, Japan, and the United States has achieved a important breakthrough in biomedical engineering. Using cutting-edge 3D printing technology, they successfully reconstructed penis tissue and restored both erectile and reproductive functions in animal experiments. This innovative approach offers new hope for treating conditions like erectile dysfunction and Peyronie’s disease, and could potentially revolutionize gender confirmation surgery for trans men. The team used hydrogel to print penis models containing sponges, white membranes, and urethral sponges in the laboratory.
The ability to 3D print organs represents one of the most promising, yet challenging, frontiers in biomedical engineering.A critical aspect of any organ is its blood vessel network, wich is essential for delivering oxygen and nutrients to maintain cell survival. In the context of the penis, erectile function is especially dependent on blood filling the cavernosum, while the white membrane provides structural support and stability.
Replicating Key Structures with Hydrogel
According to a report, the research team utilized hydrogel to meticulously recreate key components of the penis, including the sponge-like tissue, the white membrane, and the urethral sponge. This allowed them to simulate the process of blood flowing into the sponge and cavernous sinus valves, effectively mimicking the physiological mechanisms behind an erection. This in vitro model enables scientists to conduct in-depth studies of normal and abnormal penis function without relying on animal or human subjects.
The team’s approach involved accurately reproducing these key parts and simulating the effect of blood flowing into the sponge and cavernous sinus valves, so that the model can achieve the process of congestion and maintaining an erection. This in vitro model allows scientists to explore in-depth the normal and abnormal states of penis function without relying on animal or human experiments.
Restoring Function in Animal Models
Building upon their in vitro success, the research team moved towards creating dynamic models suitable for implantation in animals. They implanted endothelial cells, a crucial component of the inner lining of blood vessels, into the 3D-printed cavernosum. These constructs were then transplanted into rabbits and pigs with penis defects. Remarkably, after several weeks, the animals experienced a return to normal erectile function, and were even able to mate and reproduce.
The research paper highlights that this biomimetic corpus Cavernosum (BCC) demonstrates clinical potential for treating penile injuries and promotes the practicality of 3D printing of artificial tissues. More importantly, this technology has broad request prospects.
Implications for Human Health
The potential implications of this research for human health are significant. According to the Massachusetts Male Aging Study, more than half of cis-sex men aged 40 to 70 may experience mild to moderate erectile dysfunction.Furthermore, the prevalence of Peyronie’s disease, characterized by fibrotic plaques on the white membrane of the penis cavernosum leading to bending, deformity, and erectile pain, ranges from 1% to 13%.
In the future, this technology is expected to develop a version suitable for humans, treating related diseases, and even applying it to gender confirmation surgery in trans men. The prosperous experience of previous rabbit experiments has now been verified in pigs, showing the possibility of its cross-species application.
A Promising Future for 3D-Printed Organs
The research team emphasized that this is not only a technological breakthrough, but also brings hope to patients with penis-related diseases.From laboratory models to animal testing, this 3D printing technology is gradually moving towards clinical applications and is expected to change the future medical landscape.
the findings have been published in the journal *Nature Biomedical Engineering*, marking a significant milestone in the field. the successful replication of results from rabbit experiments in pigs further underscores the potential for cross-species application and eventual translation to human clinical trials.

Dr.Sharma: “The core breakthrough lies in our ability to successfully 3D print functional penis tissue, restoring both erectile and reproductive function in animal models. This addresses a major challenge in regenerative medicine: the precise replication of complex organ structures, including the intricate vascular network crucial for organ viability. In this case, we focused on replicating the corpus cavernosum – the spongy tissue responsible for penile erection – along with the tunica albuginea (the white membrane providing structural support) and the urethra. We used a biocompatible hydrogel as the scaffold for the 3D printing process to form the complex, tissue-like structure.”
WTN: The article mentions the use of hydrogel.can you elaborate on the material’s role in recreating the penis’s key components?
Dr. Sharma: “Absolutely. We chose hydrogel for its biocompatibility and ability to support cell growth. Hydrogel’s properties allow for the precise deposition of cells during the 3D printing process, essentially mimicking the natural extracellular matrix of the penis. This is crucial as the hydrogel supports the cells’ growth, creating structures like the cavernosal spaces that are essential for filling with blood, thus leading to an erection. This in vitro model allowed us to meticulously study the physiological process of penile erection under controlled conditions before proceeding to in vivo experiments.Its versatility makes it an ideal scaffold for tissue engineering and regenerative medicine applications, not just limited to the penis.”
