Personally, as a nurse who has had patients with chronic and acute pain. Cancer patients, kidney stone, post-ops, laboring women. I don't see a big difference gender-wise. It is individual, everyone is so different. There are some interesting studies on pain thresholds and perceptions in males v females. Some varied results. *Any natural redheads, read the first link--very interesting stuff about opioids and anesthesia in redheads.*
" Jeffrey Mogil, Ph.D., is professor of pain studies at McGill University in Montreal, Canada. He explains that while not all studies have found sex differences, those which have all point in the same direction that contradicts conventional wisdom. "Females are more sensitive to pain, less tolerant and more able to discriminate different levels of pain than males," he says. This is true in studies of both humans and animals.
Women are also much more likely to suffer from chronic pain conditions than men. Researchers originally suspected that this was primarily due to the fact that they are more likely to seek medical care in general. But while women do indeed seek more care, they're also genuinely more likely to develop painful conditions like fibromyalgia, rheumatoid arthritis and migraines. For example, 80 to 90 percent of people with fibromyalgia are women, according to the National Institute of Arthritis and Musculoskeletal and Skin Diseases.
Pregnancy actually is the exception to the rule. While pregnant, women do become progressively less sensitive to pain as they get closer to giving birth. Natural painkillers like endorphins are elevated during pregnancy and labor, helping fight pain." (Continues here)

Yet this one says:
”The socialization of gender further muddies the waters. How do society’s expectations influence the way experimental subjects report pain?“This question is really key,” admits Graham. “Boys typically learn that they are expected to be tough and not complain about pain.
One study, conducted by researchers at the State University of New York at Stony Brook, found that men reported less pain in the presence of a female experimenter than they did in the presence of a male.
”But the most confounding problem may be the complex nature of pain itself.“Pain is inherently subjective,” says Graham. “We typically rely on self-report to know if someone is experiencing it.” And it’s tough to determine how much of pain is sensory and how much is influenced by psychological factors, she adds. “The limbic system of the brain, which is related to emotion, is typically active in response to physical pain for both men and women. In fact, looking at functional MRI, it can be difficult to distinguish psychological pain—such as that caused by social exclusion—from pain that is purely physical.
”Sociocultural and psychological influences seem to have a greater impact than any inherent biological factor, believes Graham. Pain lights up our nerves and our brains in ways that are more alike than different. “Overall, I think it’s important to know that men and women respond similarly to pain at a biological level.”How much it hurts may depend upon who’s asking.—Alexa StevensonJennifer Graham, Ph.
