Use of Male Mice Skews Drug Research Against Women, Study Finds (theguardian.com) 157

An anonymous reader quotes a report from The Guardian: The male mind is rational and orderly while the female one is complicated and hormonal. It is a stereotype that has skewed decades of neuroscience research towards using almost exclusively male mice and other laboratory animals, according to a new study. Scientists have typically justified excluding female animals from experiments -- even when studying conditions that are more likely to affect women -- on the basis that fluctuating hormones would render the results uninterpretable. However, according to Rebecca Shansky, a neuroscientist at Northeastern University, in Boston, it is entirely unjustified by scientific evidence, which shows that, if anything, the hormones and behavior of male rodents are less stable than those of females. Shansky is calling for stricter requirements to include animals of both sexes in research, saying the failure to do so has led to the development of drugs that work less well in women. One example that the report mentions is with the sleeping drug Ambien, which had been tested in male animals and then men in clinical trials. It "was later shown to be far more potent in women because it was metabolized more slowly in the female body," the report says. "Across all drugs, women tended to suffer more adverse side effects and overdoses."

      Yes the lab mice used have to be the same as used globally so everyone can see the results and then peer review.
      Who wants to find out that the "mice" are now "different" and the lab can do the review?

          Except that female mice are primarily used for breeding and have this pesky little thing called hormones. They go in heat every 4-5 days. But I'm sure the entire field of biology is going to be overturned by a neuroscientist SJW opinion paper.

        • The common standard is not based on gender, it's based on genetic line. Using female mice would not be an issue in this respect for most trials.

          Of course, using up your female mice to do lab studies is a great way to limit the supply of mice. Remember, one male mouse can knock up a whole bunch of female mice. The reverse, not so much.

          Basically, same reasoning as to why farmers keep one bull and a lot of cows - it makes the bull happy, and lets you have the maximum possible number of calves....

          • Mice are known for their fecundity, I doubt that this would be such a problem. It does put an additional burden on testing though: you either need more mice to reach the same confidence, given that you now have an additional variable, or you'd need to do an additional experiment after all other testing was done to see if male and female mice responded to the drug differently.
      • by malkavian ( 9512 )

        That's the problem with that kind of testing. It applies only for the conditions that it's tested in.
        If you take a male mouse from an identified genetic line as the control, then you need to run comparisons against various other genetic lines and especially across sex.
        That'll give an idea of what kind of variability you'd expect in the human trials, or whether there are other confounding factors that simply don't show up in a single strain experiment.

      • by ceoyoyo ( 59147 )

        Yes... that gets at an issue that a lot of people seem to have trouble with. It's fine to use a very carefully controlled standard (e.g. male, genetically identical mice) so that your work can be easily replicated in another lab. *But* in order to make any kind of general statements about your findings its necessary to actually show that they hold in other populations.

      The thing is, while a mouse's metabolism isn't QUITE human, it's close enough that, to a clinical researcher, you're essentially a 75 kilogram rat.

    • Indeed. Without checking wikipedia, I'm gonna go out on a limb here and say that mice, like most mammals, experience seasonal estrous. That's quite a bit different than homo sapien's monthly hormonal cycle.

      All drugs go through human testing anyway. So this is likely to be a complete non-issue but, you know. Teh sexisms.

    because its retarded to additional variables to your billion dollar study just to please feminists (female mice on top of being an additional factor in themselves go through cycles like human women). Drug studies have several stages with additional human trials at the end with both men and women for drugs that will be for both sexes as standard anyway (if you didn't include women by this point you'd likely be in trouble) so there is no point in throwing in female mice for giggles.

The natural sympathy of juries to any problems with children, even if they aren't provably harmed by the drug under test, is a lose lose situation.

    1) males in a population are generally expendable, females less so until part reproductive age.

    2) at least in humans, the changes in bodily systems linked to hormonal/reproductive cycles are profound in females, far simpler in males. If you're doing an experiment, you want to control for as many variables as possible to make your results clearer. Using women - where your results could vary wildly depending on whether it's the 14th of the month or the 20th of the month, whether she might actually be pregnant or not, etc would increase the costs, complexity, and length of drug trials exponentially.

    3) let's not forget that women do get pregnant and don't realize it. If the new cold and flu medicine you're testing turns out to be the next thalidomide, how horrific would that be? (Setting aside entirely the likely financial liability.)

    I know that the consequences of male-dominated testing are negative for women, but at a certain point even 21st century "woke" hand wringing and implications of institutional sexism runs into the hard, cold fact of the innate biological differences between people with xx chromosomes and people with xy.

  • Is there anyone else from an industry lab here who thought we were reading a paper from the 1980s?

    Why do NIH researchers still do this? It's been the law in drug development since 1993 to have gender balanced studies. (The exceptions since '93 are very rare... Ambien was passed in '92).

    Why are they dragging drug development into this? This simply isn't true for commercial efforts. In addition to being illegal, OF COURSE it would be incredibly stupid to ignore half the population.
