Can stem cells help men with erectile dysfunction (ED) or Peyronie’s disease? Scientists have been investigating the use of one particular type of stem cell, but the data for these purposes are “deficient” according to a new study in Sexual Medicine Reviews.
The authors analyzed several medical studies on the subject.
There are over 200 types of cells in the human body. What distinguishes stem cells is their ability to develop into other types of cells. One common example of stem cell therapy is bone marrow transplantation, but scientists are looking for ways that stems cells might treat illnesses like diabetes and heart disease.
In time, ED and Peyronie’s disease might also be treated with stem cells. In the study, researchers focused on stromal vascular faction (SVF), described as “the heterogenous mixture” that forms adipose-derived stem cells. (Adipose is another term for fat. These stem cells come from fat tissue.)
SVF is “ideal” for the formation of new blood vessels, the authors noted, making them particularly interesting for ED therapies. Often, erection problems occur because blocked blood vessels can’t allow enough blood to flow into the penis.
Scientists also think that SVF might regenerate damaged tissue.
Still, there is more work to be done. The study authors explained that research on SVF for the treatment of men’s sexual problems is “limited” and that “a substantial number” of studies will need to be completed before clinical trials or practice on humans can be considered.
They suggested several areas for future researchers to consider:
- If SVF is deemed viable, at what point should a doctor suggest it?
- Can SVF treat severe ED?
- Can SVF help men who develop ED after prostate cancer surgery?
- How much will SVF cost?
- How long does it take to complete SVF treatment?
- Should any other treatments be done at the same time as SVF?
- What else can we learn about how SVF works?
“Quality basic science, translational work, and clinical trials will facilitate appropriate standardization of SVF treatment and accelerate approval by regulatory agencies,” the authors concluded.

What Is Jelqing, and Does It Actually Work?
The term “jelqing” refers to a set of penis stretching exercises that some believe can make the penis bigger. Although the practice has gained attention and popularity in blogs and internet forums in recent years, there is no scientific evidence that it is an effective way to permanently increase the size of one’s penis. In fact, in some cases, jelqing may actually cause damage to the penis, so it is a good idea to get all the facts before setting off to try it.
What Is Sensate Focus and How Does It Work?
Sensate focus is a technique used to improve intimacy and communication between partners around sex, reduce sexual performance anxiety, and shift away from ingrained, goal-oriented sexual patterns that may not be serving a couple.
What Is the Average Penis Size?
If you have ever wondered how your penis compares to others in terms of size, you are not alone. Many men are curious to know how their penises stack up compared to the average. Unfortunately, general curiosity can sometimes give way to full-on obsession and anxiety about penis size. This can be an unhealthy and often unnecessary fixation, especially because most men who think their penises are too small have perfectly normal-sized penises.
What Is Edging and Why Do People Do It?
Edging is the practice of stopping sexual stimulation before reaching orgasm to prolong a sexual experience. The term stems from the concept of approaching the metaphorical “edge” of orgasm but stopping before going over the edge.
