There is more (and new) evidence mounting to an already robust knowledge database that a man’s erectile dysfunction (ED) can be linked to a higher rate of cardiovascular (CV) events.

The latest work to be discussed here demonstrated such men had a “higher relative risk of myocardial infarction [or heart attack], total CV events, and all-cause mortality.” (1)

First, let’s review a few facts about ED and cardiovascular disease (CVD).

  • CVD is leading cause of death in men (with significant rates in young & old)
  • > 30 million men in U.S. are affected by ED
  • ED impacts > 50% of men aged 40-70 years...

This topic is somewhat off the beaten path, but when you delve a bit deeper a new research study on the penetration mechanics of the beetle penis- its bending stiffness gradient compounded by its soft tip (pictured below) – could actually hold some promise in the medical device realm.

In parts of Africa, it is common for older boys to undergo ritual circumcision as a passage into manhood. Unfortunately, the practice occasionally costs them their manhood.

The reason is that the person performing the circumcision is rarely medically trained. If the penis is improperly bandaged, it can become necrotic -- i.e., penile tissue can die. This leaves the man vulnerable to infections. If that occurs, the outcome could be very bad: Amputation or death from blood infection are possibilities.

If a man has his penis removed and wants a new one, there are two options available. The first is reconstructive surgery, often using an implant combined with tissue taken from his forearm to build a new penis. The problem is that the penis is hairy and ugly and doesn't...

Given the depth and breadth of penis articles recently, our editorial board thought not covering them would do the public a disservice. Since some in our office are gun shy about the topic (e.g. males), I was tasked with the assignment. 

No big deal. I got this junk. Being a medical doctor means being so used to penises and vaginas, to me they are interchangeable with any body part, from brain to anus. 

Some people will always test boundaries, that is why I wrote an entire series of articles on inanimate objects found in bodily orifices by doctors, and those covered the penis and urethra. Doctors are used to it, from general practitioners to surgeons.

So, let’s deep...

Humans have a much longer and wider penis than the other great apes. Even the largest of gorillas, more than twice as heavy as a human, will have a penis just two and half inches long when erect.

However our testicles are rather small. A chimpanzee’s testes weigh more than a third of its brain while ours weigh in at less than 3%. The relative size of our penis and testes is all down to our mating strategies, and can provide some surprising insights into early human culture.

Primates exhibit all sorts of mating behaviour, including monogamous, polygynous – where males have multiple mates – and multimale-multifemale. One indicator of which behaviour occurs in a species is the size difference between males and females. The greater this...

HPV—Human Papillomavirus— is a frequently overshadowed sexually transmitted infection when the topic of STDs hits the spotlight. This is unfortunate as HPV impacts an estimated 79 million Americans currently infected. (1) The Centers for Disease Control and Prevention (CDC) reports “every year approximately 17,600 women and 9,300 men are affected by cancers caused by HPV.” (2)

Due to the existence of many strains of HPV, the result of infection can lead to health issues like genital warts or an array of oropharyngeal (aka oral and throat) and anogenital (aka anus, vulva, cervical, vagina, penis) cancers. Many infected are unaware of their status and naturally clear the virus on...

Erectile Dysfunction (ED) adversely impacts over 30 million men in the United States to some extent.  Medical efforts to combat this considerable personal strain and relationship stressor are replete with various shortcomings.  

Depending upon the cause, treatment options can be limited.  Traditionally as a last resort when a man is ineligible or has failed less invasive alternatives, surgical insertion of a penile implant is considered.  

The common types that exist fall under the inflatable (IPP) or malleable (MPP) penile prosthetic umbrellas.  Innovation in this field has been relatively stagnant the last 40 years which is why a team of researchers —whose concept was recently patent-approved...

It isn’t hard to imagine that as our enlarging and ever-stiffening polarized political spheres come to a head, an article about what maintains the penis’ potency might be a kind of crowning glory.

To start, let’s give you a sturdy grasp of what prompts erectile dysfunction (ED) firming up any confusion.

More than 30 million men in the United States are affected by ED to some extent, so prevalence is certainly high (1).

The mechanism to control a man’s ability to get erect and maintain it is quite complex.  The point and shoot components are controlled by your sympathetic and parasympathetic nervous systems.  When there is impairment in either arena, there is a flawed rigidity or ejaculation.  

When nerves are firing and blood is flowing, this pleasurable...
