Do men get PMS? and how often?

Yes, Permanent Male Syndrome

As men get older and their hormones change (that is, less testosterone), it's possible for them to have emotional issues and mood swings similar (but FAR from the same thing) to a woman experiencing menopause. They couldnt handle the cramps.

No, but they get IMS.

1) "Irritable male syndrome (IMS) is a recently-coined term for a set of symptoms thought to be caused by a drop in testosterone levels in male mammals. It is a striking feature in male seasonally breeding mammals associated with the end of the mating season. These symptoms are similar to those of the so-called male menopause (also known as viropause or andropause).
In humans IMS is defined as involving the hormonal, physiological, and chemical changes that occur in all men. These changes are considered to affect hormonal, physical, psychological, interpersonal, sexual, and nutritional aspects of men's health. Stress tends to be a common trigger especially when combined with rapid hormone changes during young adulthood and later in life.
One of the most consistent symptoms is anger and sullen withdrawal present in men between the ages of 40 and 60."

2) "Male PMS: Irritable Male Syndrome

When most people think of PMS they think of women. However, researchers recently discovered that many men suffer from a condition similar to PMS called irritable male syndrome (IMS). Men with IMS often experience mood swings, stomach cramps and even hot flashes. These symptoms and others are caused by a drop in the male hormone testosterone.

IMS can manifest at any time because, unlike women who experience monthly hormone cycles, men experience a daily hormone cycle. Males' levels of testosterone are highest after waking and fall throughout the day.

Irritable Male Syndrome Symptoms
A variety of symptoms are linked to irritable male syndrome. A man experiencing IMS may experience the following symptoms:
anger
anxiety
hypersensitivity
irritability.
Changes in the male hormone cycle can also cause males to experience the following:
a lack of arousal
backaches
headaches
hot flashes
sexual dysfunction
stomach cramps.
The male version of PMS can cause men to feel antisocial and depressed and can leave them unable to concentrate."

Once a month by proxy... Everyone in my house gets it when I have it vagina or not!

Yes. PMs. Private Messages. I get them all the time.

We always tell my dad to take some midol and get over his manPMS. lol always makes him laugh.

Men do not get PMS as men do not menstruate.

Men do, however exhibit cyclical behavior similar to what women experience. This phenomenon is not yet well characterized by science, at least that I have encountered, but I have also not really researched this topic.

Personally. I seem to have a seasonal cycle, at least to some degree.
